Looking at a Road Race application on a 1968 Barracuda.…

Spring package:

350 lbs/in calculated at the ball joint wheel rate front springs (1.14” t-bars). 1.25” hollow sway bar

140 lbs/in rear leaf springs (sort of guessing at that +/-10 lbs). 3/4 “ sway bar that is adjustable

Computer wheel weight scale sheet as follows:

LF..987 RF..924
LR..731 RR..770

56% front weight bias

3412 lbs total weight

108 wheel base

**************************************************

Should I be looking at progressive, digressive, or linear shocks?

What kind of shock rates should I be looking at to control those springs in this application?

Do I need to get more info to make a better choice? If so what?
