Any good drag race leaf spring should NOT squat tsk
You want the springs tp press the rear end and tires into the ground for maximum traction up work
If you decide to go with leaf springs only, they will work fine, contact Greg Luneack at Tri City Competion in San Carllos(I think that is the correct town near San Diego) CA for a custom made set that will hook your car very well scope
