I’d hold off on torsion bars, shocks, and any other peripherals etc, and focus swinging for a set of Mickey Thompson ET Street S/S’s. Or similar. Blowing money on all the suspension parts before having tires that can dead hook is putting the cart before the horse. Get it to hook, have someone slo-mo video using their phone, then you (and if you post the video here, others) can decipher what the car is doing and you can start systematically, methodically start working on all the chassis stuff.
