Hey guys tried googling/search real quick but couldnt find the answer i was looking for but i know this has to have been answered countless times.
I'm going 5 lug and getting a set of 5zigen GN+, my current wheels are 17x9+12, the 5zigens are 17x9.5 +12.
My question is do i need a 10mm(or what size?) spacer in the front to clear my megan coils on my S13? I have 20mm overs up front.
EDIT: I crunched the numbers, if im correct, the wheel should be 6.35mm closer to the coil.
a 9j with +12 offset has 126.3mm behind the hub
a 9.5j +12 has 132.65mm behind the hub
(132.65-126.3) = 6.35mm spacer to have the "same offset/wheel position"
