vgo, it'll likely shift the brake bias forward some but street cars are heavily front-biased anyhow and at this level of vehicle I'm pretty sure that the gains you make in stopping power (which are readily noticeable) more than offset any detrimental effect of shifting the bias forward a little more.

 

oh ok...im not really sure. I just remember now reading it off the stoptech website. It was very technical.

IMO, i would find an S4 part out and grab the whole rear brake assembly. I think its a direct bolt on. Not only that, but your rear rotors will look a lot bigger. It kinda looks funny seeing 18" wheels and those tiny A4 rear brakes lol.

 

Lol my A8 brakes look like DVDs behind my 19" wheels.

 

Okay. We really need to set some stuff straight... again.

If you can lock up your tires or make ABS kick in while braking, upgrading WILL NOT do ANYTHING except make your brakes run cooler and add mass where it counts in a bad way.
