STi Group-N Strut Top Mounts - 04+ WRX / 04+ STi
-Stronger version of the stock style upper mounts. Hardened material increases suspension response by reducing flexing and camber changes.

Random Items:

Helix Endlinks (Full Pillowball)
Helix Solid Endlinks are CNC machined from high strength aluminum. This makes an excellent replacement for your factory plastic endlinks which tend to twist and bend upon corner-loading. The addition of Helix Solid Endlinks significantly increases cornering response and tightness, regardless of the use of an aftermarket sway bar or not. The use of spherical bearings allows for a much wider range of angular movement and eliminates the squeaking and creaking associated with the deterioration of rubber or urethane bushings. The spherical bearings are teflon coated to prevent dirt and debris from fouling movement.

Suspension upgrades such as high performance springs, shocks and tires can add additional stress to the chassis resulting in additional chassis flex. These STi Replica Strutbars improve chassis rigidity and reduce this flex. By using a monocoque aluminum tube shaft, high strength and rigidity are obtained without unnecessary weight gain.

The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort. The R4-S compound also has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brakes material.
Good for autocrossing, drivers schools, weekend track sessions, solo events, and rallys.
