Spring rate Question

[CA B4C]

The spring rate of the coils springs only effects the sprung rate. With a heavier rear axle you can increase the compression on the rear shocks, however, I don't think the Koni's you are running allow this adjustment. If you lowered your Panhard Bar with the new rear axle you should increase the rear spring rate. I'm running 300# springs with the Panhard Bar about 2" below the axle centerline. Hope this helps.

"On the money" answer! Don't fool with your springs! Chances are, you don't have to do anything. If you really feel a change is necessary, save your pennies for adjustable shocks. Don't waste them on other springs.

Chances are...I HAVE to do something.....the car rides too soft in the rear. So by saying I won't have to do anything, you mean get a better shock with compression adjustablility?

What i don't understand is the car rode fine before all the unsprung weight was added to it. That's why i thought I needed a new spring...nothing else changed.
