Spacers questions..Pls help.

yah, kics, H&R, Eibach all make the ones with studs built-in.

for the Z's factory wheels you want to get the ones that have the centring ring lip built-in (eibach's for example). the 10mm from kics do not have this lip so dont use it unless you have aftermarket wheels that are lug-centric.

15mm-25mm will fit the rear.
20mm-25mm will fit the front.

on the front though if you use 20mm you will need to grind the back of your wheel a little bit (like less than 2mm on an angle off the ledge) otherwise it will not clear the factory stud that protrudes past the spacer. you'll know wat i mean when you place the wheel over the 20mm, torque down the lug lightly. the factory stud will make indents on the back of the wheel. grind it off.

if you know you will be using the factory wheels for a long time i suggest you use the 20mm with new studs.
