I have a TD on a Ford frame and the springs are too hard for me. The front weight is 850 pounds on the double wishbone setup. The original was probably around 1050 pounds. Any idea what the rating should be to soften these a bit?
I built my FiberFab Ford kit on the FiberFab frame about 7 years ago. The ride height in the front was too low with the original Ford coils that had two coil turns removed. I replaced with 275 lb Heidts springs from Summit Racing shortened by 1 1/4 coil turns. If I had it to do over, I would shorten the coils an additional 1/4 to 1/2 turn to set the ride height lower by about 3/4″. The ride is great for normal street use, I don’t do hill climes or autocross.
