What is a good drag racing suspension setup?
Not too much here for specifics, but basic ideas: • Rear ladder bar suspension (do NOT use if you plan to autox, road race, or even drive hard on the street–major oversteer) • Box the lower (and upper if you have them) control arms to prevent wheel hop • Use stiff rear springs and soft front springs for better front-to-rear weight transfer • Use an airbag on the right rear spring to keep it stiffer (on solid rear axle cars, the right side tends to lift more than the left due to driveshaft rotation) • Polyurethane bushings on panhard rod (or upper control arms) and lower control arms. NOTE: Using poly bushings on both ends of the control arm will cuase binding–use regular rubber on one end. • Motion makes traction bars that bolt to new lower control arms.
