mild street suspension question

For a everyday useable street car suspension, I would certainly use better shocks. than standard off the shelf units. Even a set of cheap KBY's is a nice thing to do and worth it. I do like mine on my Magnum. (1979 Magnum)

Anti sway bars are a great idea. The T-bar, if upgraded should be up one size from standard at max. Going up two sizes creates a bit of a stiff ride most do not like for an everyday use car, even if only used on weekends.
In example, the car is a /6, use 318 T bars. Gong to a 318, go up one size. etc....

Wider tires are allways done on my cars. It not only improves grip in trun handling very well, but overall, IMO, a nicer ride feel than skinny's all around. Car feels more stable on uneven roads.

After all those major upgrade parts are done, new bushings and worn out parts should be replaced. I did a PST suspension and loved that new and tight feeling all over. No squeaks! Gotta love it.
