Looking for some advice.
I have a B5 S4 and have been planning a brake upgrade for a while, the rear callipers are starting to need attention so that will be happening soon. I live in rural Scotland and regularly get the opportunity to run out of brakes (deserted twisty open roads), I already tried an upgrade to EBC disks and pads, and have stainless steel braided flexible brake lines. But the standard size disks just cannot take the heat and fade, there just isn’t enough material for the weight of car. I am planning some engine upgrades in the future and really need better brakes prior to that.
I already upgraded to some S8 18 inch wheels to take bigger diameter disks, and have pretty much decided on the RS4 B7 setup for the fronts. Does anyone have a recommendation for the rear to go with that? Are the RS4 B7 rears a straight fit? Would some S8 rears and callipers be a viable (certainly cheaper) option? Will the standard master cylinder be OK?
Thanks in advance,
