im looking to replace my front wheel studs with longer ones because i want to run a non-staggered setup using ap1 rear wheels all around. i would lose half a cm of thread length by putting rears in the front leaving only half a cm of threads for the bolt to hold onto. i was looking at the arp extended wheel studs but they are 2.850" length and i am thinking they would be too long and my oem lug nuts will not tighten down.
standard size arp studs have a 1.850" underhead length but idk if they will be long enough?
does anyone know what size i need for this setup?

 

Have you had the centers of the rims bored out? I am o
Pretty sure the reason you do not have enough stud length is because the rears have a smaller center bore than the fronts, so when they are put on the fronts the rims don't actually fit- they are held off of the hub/rotor by a few mm which is very dangerous. only way the rear wheels will fit is if you have the centers bored out to proper specs or run a spacer. If you run a spacer you would need to get one with built in studs or replace the stock ones with longer.
Don't quote me on this but I think the front wheels have a center bore around 70mm while the rears are 64mm ( these are not precise measurements just estimates)

 

I was just about to post the same, since I don't think the front studs are any shorter than the rear studs.

 

thanks for the replies. didnt know this was the case with ap1 wheels as well
