I've searched and searched and couldn't find my answer, so here it goes. what's the biggest spacer I can run on the front and back without extending my lugs? thx

 

None, unless you buy the 25mm spacers with the built in studs. I wouldn't run anything less than 25mm with that style spacers, so if you want 5, 10 , 15, or 20mm spacers you need to install the extended studs.

 

I would say a 5mm is the biggest you can run with stock studs(others will disagree and other will agree)... If your gonna use bolt-on type, the min. is 25mm... If you plan on using bolt-on type under 25mm you will have to shave the studs if you don't have "gaps" between you lug holes on the back of your wheels... or replace them with extended studs if your gonna use 10mm+ slip-on type

 

i doubt that (sticky at the top of the page)

5mm is the largest, and even that up front takes away valuable threads and is borderline unsafe, though out back it is fine
