MRE for adjustable lock up ( centrifugal ) clutch.
Dyna for 2 stage limiter. ( got one new in box I may sell if suitable )
As for air shifter. Plenty of options. You can get just an up shift type so you can still ride back to the pits.

Oh. From what I've heard the Busa Clutch is not great for drag launches. Think its like a 2 stage thing or something ??
