Chris Think aluminum flywheel and Centeforce clutch. I just saw another shredded Spec clutch at ASW. It was their toughest but the ASW 1.8t Challenge Avant left it in 4 pieces. My Centerforce has been on my car for about 4 years and 50,000 miles with no issues. Hap, wit no da kine issues on da clutch in Evahboost, Maguire
