whats the biggest spacer i can run without needing to use extended studs?
is 10-15mm to big?

 

I wouldn't do it, but I say 5mm at most.

 

wow only 5mm damn u have any pics of ur 25mm??

 

25mm installed in the rear:

 

i got 25mm h&rs i would stick with them

 

5mm is the most on stock studs. i got about 6 turns of the lugnut before it stopped.
i suggest putting longer studs in. u should get the longest they have, in case u wanna go bigger spacer later on.
i just did all 4 corners on mine and its really easy

 

Anything past 5mm you should definitely get the extended studs. 10-15mm spacers without extended studs is way too risky.

 

I would say dangerous. Imagine how much weight the each wheel has to carry and apply the physics on turns etc... Plus, you'll notice that these nuts do not actually lock.

 

is there a diy on how to change the studs?

 

What size is your rims?

 

^^ Those are the stock 17x8s

 

I think there are a few threads for this so you may want to do a search. Otherwise, you can just buy spacers with new studs already built in. This is what I'm running. 15mm front/20 mm rear Ichiba v2 spacers with built-in studs.

 

My spacers have the studs already built in too. I wasn't gonna deal with extended the stock studs.

 

bolt on spacers make life easy, and def don't run more than a 5mm on a stock stud without going extended.

 

5mm max on stock studs....any higher, you will need extended studs.
