1972 Dodge Colt

All the stick racers(Coyote Stock & Pro Stick guys) I 've spoke with do not use clutch when shifting.They either lift momentarily or use a strain gauge to interrupt load off lugs.G-Force tells them shift it like its not yours, don't have to use the clutch. I would think all faceplated/dog ring trannys are similar.
A true clutchless never crosses neutral. Its always in a gear.
