does anyone know the diameter of the knurled part of the wheel stud? i want to upgrade to 2.5" studs. the ones im looking at are .690" o.d.

thanks for any help

 

I just did this last summer, got them from summit. let me see if I can find the exact part for you.

ARP-100-7712

I added S5 TII wheels to my vert with 225/50 sumitomo tires. Needed a 7/32" spacer, so I needed the longer studs to make it work.

 

thanks. i thought the .690 was huge and it is. the summit pieces are .485 so thats where i will be going.

thanks again

 

No problem. Now I need to slighly roll my front fenders for a little extra clearance. I get occasional light rubbing.

 

im running 17x9 -6 offset so i rolled with the eastbear unit. i just want longer studs for the sake of having them

 

then just make sure that your Lug nuts are open end,or they will "bottom out".

 

yup.

 

THOSE ARE THE WRONG STUDS!

These are the ones you want, in either 2.5" or 3.25" lengths. With 3.25" in front and 2.5" in the back it ends up being ~1" longer all around, with the front being slightly longer than the rear.

Sez you, Stud.

 

Hmmm... that was supposed to be funny, but now looks kinda rude. I didn't mean it to come out that way, Black91n/a.
