Wheel spin

What is the best combo/adjustments to get the most traction at the rear tires for a launch. Right now I have hotchkis adjustable shock in the rear and non adjustable up front. The hotchkis sway bars front and rear. Soon will be getting the hotchkis leaf springs. This my first front engine rear wheel drive car all my other cars have been awd.

90/10 front shocks
50/50 rear
/6 bars
cut rear clamps off leafs
make sure it has front clamps on
Poly bushings in leafs
sticky tires and at least 275's.
Take say bars off

Pinion snubbers can help at the track. They will not help you o the street.
