capri_83

I was at the track last night(friday) and with street tires on(first 2-3 runs) everything was ok...........but whenI put on my slicks and tried to dip into the bottle, major clutch slip...... so let the car and clutch cool down.... about an hour.... made another run with slicks and no bottle and no slip......the car has had the same Center Force D/F in it for 3 years..........should I upgrade to a new style flywheel and a 10.5" clutch(still has old 83' flywheel and 10" clutch).......and if so any clutch ideas "Ram", "C/F", "Cobra".....car has tranny can and drive shaft loop.....should I go with twin plate?????? thanks guys...
