Stud kit Sizing for a spacer

[Jake.s54]

Hey guys I am interested in getting a stud conversion kit and im not sure on the length. I have a 20mm spacer in the rear and no spacer in the front. I want the length to match on both the front and rear, is there anyway i can run shorter in the front and longer in the rear to match, or is that a bad thing. Just lmk what some of you guys have and recommend some sizing thanks, Jake

There's generally a 75mm and 90mm option, though I've also seen 63mm, but I think that was in reference to the threaded part for the wheels, total should still be 75mm.

I believe 75mm is good till about 15mm, then you need 90mm for 18/20mm spacers.

Thank you, I think I will be going for 90mm in the rear, and 75mm in the front.
