We are using OE C5 Z06 wheels in the back with a Mickey Thompson Drag radial P305/45R18 tire.
To save the CV's first and foremost you have to make sure there is ZERO wheel-hop. Wheel-hop, even if you don't feel it, will rape your CV's without any warning. Some shear the shaft at it's narrowest point while others destroy the joint itself. On most cars wheel-hop can be cured by simply upgrading the
Trailing Arms but some require cradle and differential bushings as well.
You can't dump the clutch much over 2800-3000 rpm on a drag radial if you expect the CV's to survive. Unfortunately it needs to be around 4000-4300 rpm to be in the
torque curve of the motor and keep it from bogging. It will take some practice but you have to bring the car up to 2500 rpm or so and on the last yellow begin slipping the clutch. It takes a little finesse because you have to allow the clutch to slip just enough for the rpm's to rise to the torque curve but not enough to glaze the clutch. This will progressively load the CV's instead of shock load them.
