Saleen414 is right. Look at team z or baseline suspensions for help. Personally, Kevin from baseline helped me tremendously.
Stiffening the chassis and reinforcing the torque boxes is a great start. You need some adjustable shocks and struts, springs up front, stock v8 springs will work in the rear, upper and lower control arms with adjustability in the rear, and some way to adjust ride height. An anti roll bar is a good addition as well.
