I wouldn't try making a radial tires work well on a stick shift car at the track, none of the NHRA stick shift cars are running them as far as I know
NHRA's A/S at last year's US Nationals was won on radials
I've got many NMRA customers in the 10.0@132 zone that are required to run diaphragm clutch and bias slicks in class, but switch to radials for non-class events. Since they are already dead hooking a 10.5 bias tire with a ClutchTamer, radials for them is usually as easy as just switching tires.
