Alreet, someone call me?
I had a hybrid AP Racing set up with a 360mm disc, also known as a truck load of fail, as they were like 1mm off the lower ball joint with no dust shield = sent back.
The Alcons I have now, there's loads of room behind an ET42 wheel and they are a phenominal, albiet expensive set up - progressive, super powerful and I cannot get them to fade!
GTIJames has the Stoptech set up, think he paid around £1200 from Balance and he needed a minimum 8mm spacer behind an ED30 Pescara (ET50?) which is essentially a CH. So, I'd imagine you want to be looking for an 18x8 ET40-42 wheel - which will be fine as long as you run a 225.
