If you do your brakes in on the Ring, you're doing it very wrong!
They're the way forward, I'm done modding cars forever. This and the Pork will remain untouched.
All I've done is swap the fluid (I did the pads too although it isn't necessary) and buy a spare set of rims with semi-slicks on. Job done, it'll ruin 80% of your average track day turn out. When it breaks, I take it back on warranty and no questions asked.
Sure it isn't German build quality, sure it depreciates like a rotting peach (although factor in wasted modding money and it isn't that bad) - but it costs 1/2 the price of VAG in consumables and I haven't had a car that makes me laugh out loud this much for a very long time!
