As said above, I think the Grand Am run the 4-piston in front so I think I should be good for 6-8 DEs / year.

ST60 with 380mm rotors will clear most true 18" wheel designs. The stock 18" don't offer the same clearance.

Thanks

Im actually one of the few who likes the OEM 18" rim and for now wanted to stick with it. Even if I bought a larger 19" for daily use, I'd still use the OEM 18 for the track. At least for now...
