I have seen both kits but I have personally tried the StopTech kit. Both kits are really nice. There is probably no really big differences between the two with the exception that the StopTech kit comes with front Stainless Steel brake lines. I would go with the StopTech kit because it will be easier to get tech support and the rotors are cheaper to replace. I am told that replacement parts for the Prodrive kit are really expensive.

I know that replacement rotors for the Prodrive kit are definitely not cheap. The StopTech calipers are pretty light for their size but their rotors are pretty heavy compared to stock rotors. But then again the roto is bigger. The StopTech rotors are also machined and can come either x-drilled or slotted.

Stoptech rotors are actually lighter than the stock WRX rotors.

Prodrive kit vs Stoptech....

Both kits are great and obviously function well on track and on the street. If I had to choose between the two, it would Prodrive , because they are made by Alcon,who is owned by the same guy who started and is repsonsible for AP racing calipers.
Yep,.....

The Prodrive piston quality and seals is superior, the clamping force(something I NEVER hear anyone on hear ever talk about) is much better with the Prodrive. How relative is all this,..well that depends again on its intended usage. I know one of the Speedvision teams at Road Atlanta when I was there testing had some Stoptech brakes that saw 3 sets of front calipers lock up and fail in 1 day, they went back to a regular M3 caliper and actually saw the lap time drop 3 tenths,..does that mean they are junk,..nope-nope-nope. I have heard that under extreme usage they fail. I know some teams were offered free Stoptech brakes if they just run em' and give feedback, but they dont last through practixe, NOW IN ALL FAIRNESS,..this was at Elkhart Lake where the touring car class in Speed World Challenge brake from like 140 mph and the laps are 4 miles long.

One the other end of the spectrum, closer to home I know a guy very fast I might, add with a black WRX wagon who is a regular at Summit Point and he brakes hard and throws as much abuse at his Stoptechs as anyone I see in Driver-ed events and Seat-time type events and he hasnt had any problems to my knowledge,......Mavic could verify this part.

The third example is key,.....the very popular "Brembo" Gran Turismo kits are not the same quality caliper as the "Big Reds" that comes on some Porsche's.

The best value is $ 259.00 each for Big reds,..and these have 52mm and 56mm piston diameter and are rebuildable,...made by Brembo and have been used on alot of cars at Daytona 24hrs in the mid nineties,.........
(mine lasted 4 years braking from 150mph in turn one @ Summit Point) Colemans rotors in Menominee,Michigan 906-863-8945, makes custom rotors, they supply alot of Nascar and Arca teams.
So you're saying " I dont want any Nascar rotors on my car,.."
Why not, those cars weigh 3600 lbs and brake hard twice a lap,.the rotors last me a full season. They have aluminum hats and are floating rotors and you can order whatever size you want. ..Total kit, calipers, rotors, hats and PFC pads,( and brackets, $ 900.00 . ALOT of RX-7 guys go this route and never look back. You can waiste money on pre-fab kits and never learn brakes or you can brake with the best on em'

All in all, again,.either Stoptech or Prodrive are great, as far as the comment about the customer service from Stoptech being real good,..thats great, but somethings you dont need customer service for ,...should I say,...somethings are proven.

P.s the Big Reds are at any Porsche dealer and are radius mount calipers, they dont fail.Period. if anyone wants help with this, I would gladly do all the ground work for you.

Talking got Bobby a little worked up..?

Sorry if I offended your product Mr Lee, I am just going on what I know and have witnessed, not to imply that you know off Everyone using your product, and that's not to say that eveyone using your product would let you know about it either !! As this be the case,..IMO , lord knows I better put that in there,..I would 'nt want anymore feathers on the ground.......

As I stated in my reply, StopTech has a great product, my opinion leans towards Brembo and AP brakes, and certainly now that I pissed Bobby off !

I dont think anyone would challenge you on knowing brakes Bob,.and I would hope that since you're in the business of making brakes for the world that you have had some success,..but dont think there arent some PRO TEAMS out there who have had problems, that maybe are outside of the scope of your brake crystal ball either.

As for Redline Motorsports, for you to imply that Tom Stewart's success at VIR was as a result of your brakes,..........well I guess your entitled to feel that way,.yes his performance was great, but Tom knows VIR better than a lot of guys in TC...

Road ATlanta test took place last (2002) year and I will get the specific date, and E-mail you.

Coleman floating rotor part # d30-137-200 ( DV30)
1.25 thick 13.5 o.d 12 slot .

I noticed you didnt respond to having any brake problems at Elkhart Lark last year,....maybe I will put it in question form as not to **** anyone off,...

I guess we could go on and on,..that would be a waste of time,..I apologize if I said something that ruffled your feathers, but hey this is a forum right?

Hey maybe I shold have said this,....I live in a cloud and I like my brakes on my car, and that's all I know,..forget what I have witnessed or what really goes on out there.

Oh and wow,..I guess you were reading thru the forum and got offended or a loyal customer said some guy on I-club is bashing STOPTECH?...again I apologize if my original comments got you all worked up.

P.S Bob,,whats the minimum buy in to become a Stoptech distrubutor?

We have run the Stoptech big brake kit on our USTCC racecar for a full season. These brakes have performed flawlessly and allow me to brake right alongside the USTCC BMW, which is 700 POUNDS LIGHTER THAN OUR CAR.

We have not had a single failure. The only issues we had were the proper pad selection at the beginning of the seaons, which you would have to do for any new set-up. We found the proper temperature pad on the second try. Our brakes generate an enormous amount of heat (surprising even the Stoptech guys). The Stoptech's take them in stride and I have as much braking performance in the last corner of the last lap as I do in the first practice session of the weekend. I have complete confidence in these brakes based on my experience with them and I KNOW, based on how these brakes have performed in the past that they would have no problem at Elkart Lake braking my 3,300lb car from 135mph lap after lap.

You surprise me with your comments because in the past you have shown that you understand braking theory. You should know that in a well balanced braking system, adding clamping force will reduce braking performance because you change the brake bias and cause premature lockup.

In what way are the pistons and seals of the Prodrive kit superior? I'm curious to know exactly how their better.

GARY...

Gary I thought I understood brakes before Bob got a' whole of me !! Prodrive is just MY preference, for no other reason than I drove a student's car at Summit Point at a SEATtime event and were very impressed with them,..that's it,..

The car I drove had ABS disabled and I could go deeper and deeper and it just took it, the car stopped. I was obviously impressed. Granted if you weed through all the sarcasm, I did apologize to Bob Lee,..but the second I start naming names on who has had problems, then its alot of crap. So I only named one person who has had great results.

The pair of calipers from Prodrive that I saw off a car once were in very good shape, and I had just rebuilt my Brembo's and know that , that person had been at the track with me 90% of the time I was there,..so it left me with a strong impression about the quality of the product.Granted they dont brake from 150 mph at 200 ft either,..so it's all relative.

My initial reply should have been kept to a minimum and explained in a way as to suggest , " if you want an inexpensive way of building a kit piece by piece that will work well for a long time,....then try this." Instead I did like I am guilty of doing on here, which is bringing racing into it, and I obviously offended ole' Bob Lee. His response just sounded like,.. hey Stoptech is changing there name to WORLDBRAKES, 'cause there are no other,.." there will always be someone with a second opinion and someone who has witnessed some things that seem impossible, especially the way Bob made it seem like, they (STOPTECH) have no problems.

I am a driver first, then an instructor, beyond that I know somethings based on my experience. I have built some great cars, and helped customer's ( wealthy Benz customers who race all other makes) build racecars that have won races,.on all levels.
And this is not directed at you G.S., but I am opinionated about certain products and will continue to use those,........NOW,...would I let my PRODRIVE impression sway my choice in brakes for a racecar,..( this is the part I dont think BOBBY understood, he just got torqued up so quick) If I were , and really should I say, when I build another customer car, I will use whatever manurfactors products are winning and last the longest, regardless of price,..so if Mr LEE lives up to his claim,..I might need a pair of the WORLDBRAKES,..I mean STOPTECHS, it'sjust now,...he problably would nt sell them to me !!!

Hope I answered your question. As always, it's good to hear from you, just not under these circumstances.

Yes. I am MORE than happy with the performance of my Stoptech Brakes. I run the Stoptech Club Race pads at the track and have never experienced any fade or problems. The brakes are consistent from the first lap of the first session, to the last lap of the last session. Given, I know this isn't at the race level, but I do know that I am A LOT harder on the brakes than a lot of people because I am so confident of their performance. I have a lot of in-car footage of me passing cars that are faster on paper, but I catch them and get waved by (a nice thing about track days vs racing ), and I'd say it's 90% under braking. I make 2-3 car lengths in some of the hard brake zones at Summit. I also run the bigger Legacy rear rotors, stainless lines all around, ATE Super Blue or Type 200, and Axxis Ultimates in the rear. All those things help a little too, but I know that 80% of the braking in the WRX is up front, and that's why am so glad I have the Stoptech kit to take care of it.

where my heart is,.....

Let me be clear, and not misunderstood. I am not " the type of person" who,......"only buys name brand,.."

I am however, the type of person who buys the brand that is winning in either the top level of motorsports or the closest comparable level to where I am. What I do see when I walk through a ALMS "hot pit" or Grand -Am pit, is the brands I mentioned. So I look forward to a day in the very near future that I see an affordable brake manurfacture supplying the top teams with a winning combination, if that happens to be STOPTECH, then that's when I'll make the switch. And I only hope the affordable part stays the same.

I certainly dont anyone to think I'm a POLO shirt, ROLEX watch, PORSCHE driving kinda guy. If that combination makes the determining difference when making deals on the golf course,...
( not that I would deal with the kind of person that, that would make or break a deal) then that'll be the combo for making deals.

Brakes are a little different, they do this small part in the whole equation called stopping mass. And since I was at the track the day one of my fellow instructors lost his life in turn one,( not from brake caliper failure) from a brake issue, I take brakes very seriously. So I'll stick with what I know works for 97% of the teams in the sports car racing in the US.

Who knows what the future holds,..right?
