Seconded for AP. I came the same way, through S3 fronts. Car and I out grew them on track and I have 6 pot AP's with floating rotors. Staggeringly good brakes whose residual value should they be removed is high. They'll also upgrade newer vehicles such Mk7 Golf R etc. Road only use I'd suggest a neat light weight 4 pot kit from them. If cost is an issue then the S3 kit front and rear is a very good upgrade, particularly if you won't be doing track days. On the road they are easily good enough for 350bhp with the right pads and fluid.
