Spring diameter is 3 1/4 inches in the front, I can only assume it's the same on the rear.. What is that of the raceland or equivalent? I'm running a 37 offset on a 7.5 inch rim. Well, I was until I realized I had clearance issues. Back to stock wheels until I find a solution.

Since I'm doing the rear disk brake swap through your group buy, I'm hoping to use that as my 'spacer' to get the clearance I need.
