Posted on 246 as well. I'm still unsure, i think despite heading down to see MRC on Saturday i'm going to have to leave the brakes until i do some more research. Most people seem to say the B5 rs4 are "okay" but they're fitted to a car with 380 as standard so they have to do their job. I'm hopefully uprating to 330hp on saturday so was concerned my S4 brakes might be on the weak side. My reasoning was why pay £300 for ok (B5 Rs4) brakes when you still have to pay £400 for discs. Everytime they'd worn out i'd be gritting my teeth thinking if i'd put that initial outlay i would be spending this £400 on B7 discs.
I have to say though, the more i think about it the more i really can't justifly £1500 or 25% of the value of the car on brakes! I may just go for the B5 setup and keep my eye out for part warn discs etc...
