WHITELINE
Whiteline Anti-Lift Kit – Race, Standard and Comfort
Suitable for MY01 - onwards WRX and STi Model Impreza. The Anti-lift Kit (ALK) is designed to add 0.5 deg static positive castor to both front wheels while introducing a substantial amount of front anti-lift. With the ALK fitted to the WRX a softer suspension will be present during braking and acceleration, this will help traction, as the wheel will be able to track the ground more precisely. Also in terms of balance the front end will have proportionally lower roll resistance during traction or braking, aiding in reducing the power understeer that is present in these cars.
The ALK is available in 3 different options, Comfort, Sports and Motorsport. Most people prefer the Comfort or Sports with the Race version being a little to stiff for certain people.


Whiteline Steering Rack Bushing
These bushings are direct replacements for the softer stock steering rack bushings. Made of high-quality polyurethane, they will firm up the steering feel. The Whiteline steering rack bushings greatly improve the turning of your vehicle. The stock bushings will flex allowing the steering rack to move slightly. This causes you to loose the feeling of the road. These are a great piece for anyone wanting to be more in touch with thier vehicle. Removal Tool is included with this kit.


Whiteline Spherical/Adjustable Endlink
Endlinks attach your swaybars to your control arms. These endlinks makes an excellent replacement for your factory plastic endlinks which tend to twist and bend upon corner-loading. The addition of aftermarket endlinks significantly increases cornering response and tightness, regardless of the use of an aftermarket sway bar or not. Whiteline Endlinks are available in two varieties: 1) Bushing Type Endlinks: The use of bushings allow for a more compliant endlink than the spherical bearing type. These enlinks will be quieter and less harsh feeling than spherical type endlinks. 2) Spherical Bearing (Pillowball) Endlinks: The use of spherical bearings allows for a much wider range of angular movement than stock while improving response by eliminating suspension compliance. The spherical bearings are teflon coated to prevent dirt and debris from fouling movement.


Whiteline Bushing Endlink
These kits utilise a high strength alloy link filled with ultra low compliance polyurethane bushes. Critical hardware is replaced with high tensile components to match the higher loads. The endlinks performance low compliance sway bar link kits are designed to replace the high compliance original original equipment versions on most Impreza, WRX.



Whiteline Front Roll Center Adjustment Kit
The Front Roll Center Adjustment Kit from Whiteline is designed to raise front roll-centre geometry by using new special ball-joints, while maintaining original bump-steer by using new tie-rod ends. Changing front suspension geometry by raising roll-centre, results in substantial increase to roll resistance and significant reduction of suspension compression of outside front wheel during cornering through improved weight transfer distribution. During cornering, this leads to significantly reduced understeer through reduced front wheel compression, as well as improved steering feel and precision and vehicle stability.


Whiteline Diff. Bushings
This kit is designed to lock the front of the rear diff support outriggers where they mount to the body. Fitting this kit will reduce rear-end float under acceleration and drivetrain "thump" under hard gear changes.


Whiteline Diff. Lock Bolts
This kit is designed to lock the rear-subframe on the Impreze, WRX, STI and some Legacy models. Locking the subframe limits the amount of movement under hard cornering, thus improving handling.


We have plenty more Whiteline products, sway bars and packages so please PM or call to inquire about other items or packages.

Type OS Cusco Strut Bar

The most popular of the Cusco bars is the Type OS. The classic design features a tubular aluminum oval shaft with a high polish finish. The aluminum bar possesses high rigidity due to the two different designs available. The Type 1 is pressed ribbed while the Type 2 is sectioned. Cusco has already chosen the ideal design for each application. The end plates are painted the traditional Cusco blue and come with all the required hardware for installation. It bolts on in minutes using normal hand tools.


Cusco Type I Lower Arm Bar
The Type I lower arm bar features a tubular high-tension lightweight aluminum design, coated in anti-corrosive paint for protection against the elements. This bar improves body rigidity by connecting the lower arm points, thus preventing body flex and therefore dramatically improving steering rigidity, response and traction. The Type I bar is a 2-point setup and includes all the required hardware for installation. It bolts on easily using normal hand tools.


Cusco Type II Lower Arm Bar
The Type II lower arm bar features the same tubular high-tension lightweight aluminum design and anti-corrosion paint as the Type I. The difference though, is that this bar improves body rigidity by connecting the lower arm mounts in multiple positions rather than just two, thus greatly increasing the rigidity over the Type I style. Body rigidity is maintained on even the hardest of cornering and dramatically improves steering rigidity, response and traction. The Type II bar is a multi-point setup and includes all the required hardware for installation. It bolts on easily using normal hand tools.

COBB

Cobb Tuning Sport Springs
Direct replacement for the factory springs, and designed to work with the factory struts, the COBB Sports Springs reduce the ride height by 2.0" Front and 1.5" Rear. The result is improved road handling and reduced body roll. Precision CNC cold wound high quality Chrome Silicon steel construction. The springs are powdercoated COBB Blue in a unique process for protectionagainst the elements.

Spring rates are increased approximately 25% over stock which results in a sporty feel without being unnecessarily harsh or bouncy. The factory springs are actually too soft for the stock struts, much less uprated aftermarket replacements, to work optimally. Our final spring rates are the result of extensive real-world testing and consumer feedback.


Cobb Tuning Tubular Sway Bar Set
Cobb's sway bars are designed to greatly reduce body roll and provide a much more predictable handling characteristic without decreasing the ride quality. Our bars have been carefully balanced and when used as a system, understeer is a thing of the past. To allow the driver to cater the system to their tastes, the rear bar is adjustable which can provide more or less oversteer for given conditions.
What makes these bars unique is their hollow (tubular) construction which results in a much lighter and technically superior design compared to the lesser solid bar design. This is the very reason why you'll find tubular sway bars used on high-end performance vehicles and race cars. The tubular design is more expensive and more difficult to manufacturer but that should not be any excuse for not offering the best solution possible. From even a purely aesthetic point of view, the style of the thick, aggressive 25mm diameter sway bar easily visible from behind the car screams that you're serious about performance!!


Cobb Tuning Endlinks
CAD designed and CNC machined from 0.5" thick billet 6061-T6 and hard anodized for a long lasting finish, Cobb's Rear Swaybar endlinks were shaped specifically in Cobb's in-house Finite Element Analysis (FEA) software for optimal strength, weight and durability. Sold as a pair complete with zinc plated heat treated steel spacers. Direct bolt-in replacement for the factory links.
To improve the feel of your upgraded sway bar, Cobb uses Teflon coated spherical bearings which are precision installed, mechanically retained and chemically bonded with ultra-tight clearances to eliminate "rattles" that may occur due to loose bearing fitment tolerance occasionally found in other endlinks.
The aerospace-quality spherical bearings are utilized at all connection points and are constructed from heat treated, hardened stainless steel and are rated with a static radial load resistance of 17,900 lbs (over 3 times the load resistance of bearings used by some competitors).
Cobb's kit also includes rubber isolators designed to eliminate any unwanted noises associated with using racing spherical bearings.
Compatible with Cobb's sway bars, stock sway bars, and most all other aftermarket swaybars designed to replace the factory units.



Cobb Tuning Adjustable Rear Sway Bar Mounts
These mounts are designed to allow for proper end-link alignment when using Cobb's adjustable Tubular Rear Swaybar. As you use the stiffer sway bar settings, the rear endlink is placed at a compromised angle which reduces effectiveness and increases the chance of the endlink bending. Changing the sway bar design would only change what positions compromise the rear end link angle. With the COBB Adjustable Slider Mounts in place, you can now adjust the sway bar's position with relation to the end link. This allows you to keep the end link in the most effective position relative to its pickup point on the sway bar.
Not for use with the STOCK rear swaybar.

PORTERFIELD

Porterfield R4S Brake Pads
R4S pads are for high performance and heavy-duty street conditions. Perfect for prolonged everyday street use while also being capable of tolerating the most severe street use without any fade. Rotor friendly of course. The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort. R4-S compound has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brake material. Good for autocrossing, some drivers' schools, and rallies. The R4-S compound is available for virtually any vehicle sold in the US. We also offer the R4-S in pad sizes for competition type calipers that are used under street driven conditions.


Porterfield R4 Brake Pads
R-4 Full Race Compound Designed specifically for heavy-duty motorsports. The carbon based semi-metallic R-4 materials allow the pad to absorb tremendous amounts of heat and dissipate it at very even rate. Carbon Kevlar material warms up to race temperature quickly, which is quite helpful during restarts, and when track time is limited. When used with cast iron and steel alloy rotors, the R-4 compound requires minimal bed-in period. Throughout the entire heat range, the carbon kevlar material will give extremely consistent modulation and predictably. This is truly the most rotor friendly racing brake pad material ever. Good for road courses, oval track, rally, vintage racing, autocross, club events or professional racing events.


Motul RBF600 Brake Fluid
RBF600’s very high wet boiling point (421F) superior to conventional DOT 5.1 non silicone base fluid (356F min) and DOT 4 (311F min) assures efficient braking even under humid and moist conditions. Indeed, DOT 3, DOT 4, and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling points and increases the risk of boiling the fluid. RBF 600 Super Hi-Temp racing brake fluid was developed for high heat and the extreme pressure demands of professional racing. RBF 600 has a low viscosity blended with unmatched performance in the most extreme conditions for minimal hydroscopic effect and very low compressibility. The RBF 600 will give solid pedal feel, great response, super high heat protection and maximum life.

Swift Performance Springs
These performance lowering springs are made with H5S.TW material.

These springs are designed uniquely for each application. The goal for these springs is to maximize the handling performance. The center of gravity is lowered but not to the point where it causes a negative effect with the stock geometry of the suspension. While some spring are designed to lower the car, Swift's are designed to maximize the performance without sacrificing the comfort.

Many believe that the better performance requires less comfort. The fact is that the harder the ride comfort the less the suspension is doing its job of absorbing the irregularities in the road itself. The suspension needs to freely compress and expand while limiting the movement of the sprung chassis weight that rides on it.

With these concepts in mind, the Sport Mach Springs are designed to maximize all aspects of spring performance.
Available for:
02+ WRX, 02+ WRX Wagon, 04+ STi, 05+ LGT Sedan/Wagon and 04+ Forester XT.

ENDLESS

Endless Vita Nuova Brake Pads
Vita Nuova is Endless' most popular, entry level compound for the everyday sports-minded, city driver concerned especially with safety. For the spirited driver, factory brake pads may feel stressful at times. If so, this compound will appeal to you. This pad focuses on safety and stopping power. First impact, controllability, pedal feeling, noise level, and pad life are all stable for safer driving within the street stage. We produce this compound for most Japanese-make vehicles. We want to produce a safe feeling for all spirited drivers. This is what Vita Nuova is all about. A typical factory brake pad's life and noise level are crucial factors during development. Its potential is lost and the average coefficient of friction is low. Many have probably experienced scary braking situations. Vita Nuova increases the level of the average cofficient of friction. This is necessary for safe stopping power.

Non-Asbestos
Driving Field : City - Street
Recommended Tire Use : Radial Tires
Appropriate Rotor Temperature : 0-570 Degrees F
Average Coefficient of Friction : 0.30 - 0.35


Endless Super Street Sports S
Endless has researched the correct rotor temperature ranges for the spirited street driver. The rotor temperature range for this compound is wide and mu-level is consistently stable. Thus, brake pedal force does not change considerably at different rotor temperature ranges and braking performance levels maintain consistency on the street given most situations.

This is a very controllable compound that is set at a high mu-level. After fade, recovery is achieved while brake performance does not worsen, returning to the mu-levels achieved before fade, right away.

Part of the Non-Steel Series, Endless uses a Non-Steel Developmental Process using a new, mild ceramic material to increase rotor friendliness. With no steel materials, dust is minimal and rusting is prevented, enabling ease of cleaning wheels (even with water).


Endless Type CC-X Compound
Proven to perform well on both street and track conditions, this original formula, ceramic carbon metal base compound has the ability to perform for a wider range of users.

For the street where low temperatures are frequent, this pad performs well causing less damage than most semi-metallic pads. Usually, semi-metallic pads sacrifice initial response to perform better at higher temperatures, but the CC-X is able to do well at initial response as well.

At higher temperatures, pedal feeling responds well while maintaining controllability with a stable coefficient of friction. Please call before ordering to verify correct part number due to differences between years.


Endless CC-A Brake Pads
The emergence of heavier and more powerful vehicles has led to the development of the ultimate semi-metallic, street compound with impressive pedal feel and the lowest levels of disc rotor abrasion, noise, and dust levels amongst the CC line-up. Perfect within the street temperature and speed range with a high level of braking force and controllability.

Ceramic Carbon Metal Series
Driving Field : Street

Endless Stainless Steel Swivel Brake Lines
The fitment portion of the Endless Swivel Steel Brake Line includes an original swivel mechanism that allows for spinning to reduce tangling and decrease chances of breakage. This swivel mechanism can also be securely locked into place as well. Brake hose material is made out of a teflon tubing covered with SUS 304 stainless steel finely knit meshed blades. Additional black clear coating finish for protection against mud, gravel, cracking, and debris. Suitable for all seasons. Match and fitment test performed on each vehicle application to determine optimal hose layout for easy to use, correct installation. Produced only for specific vehicles.


Endless RF-650 Brake Fluid
The RF-650 is used in F1, WRC and Paris Dakar Rally, yet is still available for the end-user desiring the highest performing brake fluid. Within the circuit stages where the braking temperatures reach extremely high heat situations not encountered on the street, extremely stable performance characteristics can be achieved. The RF-650 is slowly being recognized as the highest-spec brake fluid around the world. Endless continues its 4th year partnering with the Honda Racing F1 Team and is both currently supplying and testing with a handful of other F1 teams. This fluid is also used in the Porsche 911 GT3 Cup (997) cars. Unlike many other fluids that uses a recycled material in its formula, Endless uses a pure material in its original formula. Exceeds DOT 5 Standard...Dry Boiling Point: 323 Celsius (613 Fahrenheit) Wet Boiling Point: 218 Celsius (424 Fahrenheit)


ZEAL

Zeal Function X
The Function X is similar to the Function XS but features more aggressive valving and is 30 way damping adjustable. For the next generation hard user, we’ve developed the Function-X Series. The Function-X is now born. With advanced damping capabilities in effect, our efforts have recently focused towards our new “X-Coil Hyper Spring”. Through consistent and progressive research and experience, we’ve improved spring quality to achieve an even smoother and more responsive feel and ride. The ability to grasp precise road data has improved. The X-Coil spring achieves exactly this. Our Dynamometer Data proves this with stable rebound and compression levels (within a 0.1 Meter Per Second range) for level travel at very low speeds, very high speeds, and everything in between. By keeping very detailed, precision spring motion in mind, we are able to set the shock’s piston valving to superior levels. The combination of the shock and spring is superior. Our Linear Spring Motion with no Friction Loss is superior and the shock can be adjusted very precisely (Function-X includes 30-Way Damping Adjustability), thus the setting levels have broadened and can be fine-tuned with advanced precision and feel. Lightweight aluminum upper mounts, spring seat preload and spring seat locks, height-adjustable lower brackets and lock seats (for non-strut type applications) include a durable, Alumite finish for rust proof characteristics. Steel shell casing includes a special chromate plating for rust proof characteristics also. Adjustable brackets are newly designed and slender. Driving feel is amazing for the hard-user. MacPherson Strut-Type systems are specifically produced as an inverted-monotube type. Hard Spring Rate: FT: 10kg/mm RR: 8kg/mm *Custom spring rates available at no additional cost.
