in here.

Here is a photo of a stock A4 rotor and bracket and the A8/TT parts.

I dont plan to install these until sometime this spring but I did fit one up to be sure it is usable. Goes in easy and does clear the 16" A4 stock sport wheel. The FAQ says this also works on the A6.

FYI, the A8 rotor weighs 2.5 pounds more than the A4.

Have been using it for 3 months now. I am using EBC greens but will be changing to Porterfield R4s because the grees squeel way to much no matter what "fix" if applied. They stop great however both in the dry and in the wet. I have not, nor do I plan to do any "serious" track work.

BTW, don't forget to install stainless brake lines. Worth the money.

Please don't take offense. I'm just wondering why someone would want to spend the money on this when to me doesn't seem to be worth the price in performance?

Hate is too strong. The Greens just annoy me.

I saw about 5ft 60-0 reduction using my G-Tech with my G-Force tires. Your mileage may vary.<ul><li><a href="http://pictureposter.audiworld.com/AudiWorldPics/leszekm/brakefaq.html">My brake FAQ</a></li></ul>

I guess it depends on your definition of performance. If you need more braking for racing, then you should spend the 3-5 times this "kit" for multi-piston calipers, drilled/slotted rotors.

If you just want to take advantage of the potential braking improvements that come with bigger rubber (I use 225/40x18 Pilot Sports except in winter) then the added leverage of the larger rotor is the least expensive way to get there. I found that on a clean dry road, even with the EBC Greens (mine have never rattled or squealed by the way) I do not have enough brake power to lock up these tires in a straight line stop. That means I am leaving a few feet of stopping distance behind me in a panic situation. Some day I may wish I had it.

Did you crosshatch the rotors before installing them?

I noticed they do not come that way. Both EBC and Audi recommends this to improve pad seating and reduce the tendency for (any) pads to squeal.

This setup (with the stock A4 rear) is similar to the TT 180Q and A8 setups.
