Stoptech big brake kit. review
« on: April 27, 2006, 12:02:19 AM »
After much debate and frustration with my OEM brakes i finally broke down and had Randy get me some Stoptechs. I was also looking at the STaSIS/Alcon system, but i could not justify the extra $700.

The stoptech boxes are well packed and organized and everything needed was included in the kit. The kit consists of Calipers, mounting bracket, 332mm Aerorotors, stainless steel lines and brake pads. Each kit is designed and proper piston sizes are spec'd based on the vehicle weight and dynamics. Many of the 4-piston kits run the same ST40 caliper but each kit is spec'd with a combination of the 9 different pistons avaliable.  After talking with the folks at STaSIS and the folks at Stoptech both preached brake balance and brake bias. Each company had a marketing spin on why one was better than the other. To be honest i am not sure how much is truly hype and how much is fact.  I did know that with either kit i would be happy and my OEM brake woes would be gone. Both companies recommended upgading the rear rotors and pads while i was at to make sure proper balance was maintained.

The install was a breeze. I was really suprized how easy it was. Up until this point i had not taken apart an Audi brake system.  With the exception of the hub corrosion and a pre-stripped brake line fitting everything came off the car without a problem.  The Stoptech mounting bracket slipped right into place and the calipers slipped right on. The pads were easy to install and can be easily repaced by removing a re-enforcement brace in the back of the caliper. Take the brace out and slip new pads in. Nice and easy.

While we were at it i had Randy get me some Stoptech Slotted rotors for the rear along with some new pads.

Pad selection took me some time. Again i consulted many people and talked with both Stoptech & STaSIS about it and i determined the following. For my car and my driving style the Axxis Ultimates (all 4 corners) would provide me the best balance of performance and solid predictable bite for street use year around. I can also keep these pads in the rear brakes for track days. For the front during track school (june at juanta) i will install a set of Ferrodo DS3000's and maintain the Axxis pads in the rear.  The Axxis pads has very good cold temp friction and maintains it predictable/constant friction to about 950 degrees. Which is about 50-100 degrees lower MOT (max operating temp) than the Ferrodo DS2500. But the Axxis have better cold friction properties.  So it is a good combo for day to day use.

I was able to bed the pads last week and have been driving them for several days. All i can say is i am very, very pleased. The overall stopping power is amazing. The car brakes more evenly. Now that the pads are bedded i do not have the huge front end dive that traditionally happens. It is more of a central braking. The car just hunkers down and scrubs speed quick. The back brakes are definitly doing more work now and i am glad i upgraded the pads and rotors back there.

Brake fluid was selected by Randy and he installed the Pentosin Super DOT4. It has a slightly lower wet & dry boiling temp than the Motul RBF 600 but about the same as the Motul syn  5.1. But is fully compatable with any remaining fluid in the system.

the only thing i want to do is re-bleed the system 1 more time now that everything has been bedded and heat cycled.

Here are a couple quick pics. My wheels and car are dirty but oh well. The wheels are 17x8 OZ SL's (16lbs) and there is about .25" between the caliper and the inside of the wheels barrel. They are very low key and do not stand out at all. I like the fact that they are black and blend in with the car.:



This pic shows the caliper clearance near the wheel barrel:


Here is a pic of the back setup:



Lastly and most importantly, MANY THANKS to RANDY! He spent his friday night hanging out in the shop installing these with me and he also gave me a great deal on the package.

Great write-up!! You sold me; I'll have to pick up a set for myself :wink:  :lol:  Seriously though, very nice review.  I couldn't add a single thing, except for those thinking about picking up a set of these, CHECK YOUR WHEEL FITMENT AGAINST THE TEMPLATE FIRST!!  As I have found out, some 17's will fit where some 18's won't.

And I too owe many thanks to Randy for his help with my set!! :beermug:

Beautiful. If you can, cut, paste and add this to the "Reviews" section of the site. That'd be awesome. It might also be a nice addition to the Tech Guides.

If you could add it to the reviews like JR said that would rock!

Great writeup.

It would be nice have these, but since Ian proved that my RC's won't work, I would have to find another solution.
If it ain't broke, take it apart and fix it!

As I was thinking about this the other night, Dave, I think they may have worked with a 5mm spacer.  I forget that the stock wheel is a +38 offset, so the wheel will tuck a little further under the fender than the +35 of the Centerlines.  I think that the +33 combination of the stock offset and spacer would still keep the wheel under the fender, and maybe clear the brakes.

If the brakes are for the 337.  I have the GLI wheels (same as 337, but painted) and I ran 8mm spacers front and rear.  The wheels on the front looked amazing... and I didn't hit the fenders.  The rears, I wouldn't do 8mm again... they are "big enough" according to H&R, but I would use 10mm because I had a couple of the 8mm ones that the hub flange broke off on.

Pictures are in this thread so you can see:

you can run even bigger spacers in the back than that. on my 17x8 w/ 35mm offset i ran 15mm spacers and never rubbed. i tried to find a pic, but i can't.

I need to get some spacers for the Jetta...the rears are so tucked then put a 235 on it. And just so you know Eric, I've written 3 or 4 reviews, but then Jay lost them when he upgraded the site :?
Love you Jay ;) :D

Jack -

Have or had the GLI wheels?

I don't think they are lost, they are in a backup file somwehere I need to find. We had like 20 reviews, they were great.

They are relaly beneficial because they help answer users questions and can save them time from posting for feedback. Not to mention users can comment on the reviews it is nice added content.

Unfortunately, things do get lost, so I hope I can find them and jam  them out there again.

yes you can, but having wider in the back hurts cornering performance, but does increase straight line stability.   doing a 10mm and 8 fronts won't hurt performance.



And Ian... Had...  34k rocks them for his winter wheels now.
