I always talk to a guy at the track who is a stick shift racer. He runs in a heads up crate engine class with a clutch setup just like madscientist said.
When I first met him he ran a tremec but now runs a G-force G101A. He always tuning his clutch for the track. He run high 9s at legal weight in a fox body.
I was thinking of putting a stick in my car since we have a group that bracket races them but too much money and work for me.
You will have to hack the TB cross member to get a Gforce in an e-body
