I knew this in advance and it was not a major issue for me. I have the 19's and like running road tyres on track and even if I want a track tyre, toyo now do a 19" R888 and theres always michelin psc's. I just thought I would mention it as a lot of people prefer 18's for the greater range and expense factor.
I would not have posted at all however, if it werent for the caliper issue. That is the biggest problem for me, and personally, if I could choose again, I would have gone for the stoptech kit, even though the Brembo looks sexier.
