The Centerforce clutch is just not cutting it for me anymore. I get about 15 minutes of hard driving before it starts slipping like crazy now. I ordered a Exedy Stg2 this morning It was recommended to me by a friend with a turbo Teg. He's making a lil over 300whp and said even his Exedy stg1 held on for quite awhile. Did I make the right choice? Do I need a different flywheel? Do they have different surfaces on them that provide more grip?
