While I may wait another year before doing so, I believe I am ready to go to a welded or spooled diff in my 84 GTI. I am currently running open with 650# front and 350# rear springs and Bilstein HD's (not yet re-valved). With "correct" tire pressures (Hankook 211's), the car is just a bit loose and I am starting to learn how to take advantage of that.

Two questions:
How much will I need to change spring rates (no front bar, 2 rear bars) to take best advantage of the welded (or spooled) diff?

How will driving style need to adjust? I am not worried about the paddock or street as I spend very little time there!

Thanks all!

P.S. I have searched the archives and will try to compile all the tidbits I am finding as well.
