would s8 brakes be a bolt on upgrade for a s4? im pretty sure the only difference is the diameter of the rotors.

I vaugely remember a few people doing this as a rear brake upgrade, but it's a been a long time. STFA at audiwolrld.com, you may find something. Everyone goes aftermarket these days. If you're looking to save some $, I'd look at some high quality pads on your stock brakes.

so its pretty much just the rears that ever get upgraded?

you do have the RS4 calbers on there are those the same size an all as the R8?????

i dont know...i know that they fit the stock s4 rotors no problem and they are 321mm guess ill look into it....

hmmmmm i did see something lke that eather online or in a magazine but i am not sure tho... arnt R8s rotors drilled?

just found some O.E. s8 rotors and they are 345x30 and the rears are 280x22. think i would need any adapters for that?

i have no clue on that one.......most like i would think tho......

hmmmm.....wonder if i would just need spacers for it? ill just have to ask around....see if you can get some of the bozeman guys to respond about that gtg

I would question if they would clear your wheels, and I believe you would need carrier adapters (034 has them), but that would also depend on the generation of S8 you are getting the calipers from. S4 calipers are already pretty beefy, and I agree with Rammy - new rotors and Hawk pads would be worth the cash. Plus, it would be more beneficial to upgrade the front brakes because that's where the most braking force is applied.
