1. Remove front sway bar
2. Box rear lower control arms.
3. Add stiffer bushings to the arms, and torque arm bracket.
4. Install Spohn antisquat brackets. (weld on)
5. C/E adjustable drag shocks.
6. Tubular panhard rod.
7. Sticky tires.
This is all I have done to my car. 1.57 60' times with ET streets. I still do not see the need for the expensive TQ arm. I just added a looser converter, so I am hoping the 60's improve. The Spohn brackets will help the rear lift. Just transfering the weight only, will cause the car to squat. When this happens the traction hindered. I dont have alot of money in my suspension, and it works well.

I'd start off with just no front sway bar, slicks, and some frame connectors. 425hp isn't a whole lot you'll easily be able to hook that on the factory suspension ...so long as its all in good shape.
