So the standard front spring is 0600.250.0275, while the standard rear spring is 0700.250.0350. Swapping them at a given collar height will result in the front going up an inch, and the rear going down an inch, so depending on the desired ride height you may not be successful in swapping them from one end to another. If you are at a specific height, you could lower the collar 1" in the front (plus/minus whatever threads to get the same end height due to the change in spring rate) and raise the rear 1" (plus/minus again).
Your car must have been slammed initially! I'm planning on (more or less) lowering my car as close to 0" as possible.
Mark's a great guy, another ITR friend  He believes I shouldn't have to lower the car at all but I'll probably lower it half an inch or so. We'll see.
Did you keep the factory rake? I plan to initially.. need to measure it before install. |
So can we confirm that the fronts should take 6'' and the rears should take 7''? No matter what rates we choose to go with?
