I am looking to do a few upgrades to the suspension of my car. The car is a fully restored 68 charger, 470 stroker, 4 spd 4:10 gears with a 325/50/15 rear tire and stock size front tire. I have disc brakes in front and power steering.
I am not trying to make this an autocross car by any means, just upgrade the ride. All the steering linkage, ball joints, shocks etc. are new. A few problems I see are stock small block 40 year old torsion bars and sway bar coupled with new super stock springs in the rear.
My thinking was new torsion bars, a new sway bar, Hellwig? Also new shocks all around, QA1 or Bilsteins maybe.
Any recommendations for the torsion bars, shocks and sway bar?
Will the super stock springs hurt me? They are in the upper hole allowing the car to sit as low as it can with them.

Thanks!
