Default Which wheel studs

I have a set of 15x10 Prostars... and will be running a spacer. What wheels studs should I get for this? I still want to be able to run my Z06 rims and a closed end lug. Can some one point me in the right direction

When we put in longer studs, we had to run open lugs on my stock Z/28 wheels.

Maybe someone else can help ya out.

due to the thick center section of a prostar not to mention the added spacer will make those 2.5 ARP studs a bit short...I don't believe they will pass tech...You REALLY need 3 inch studs to pass correctly

1.5 studs are WAY too short...not to mention VERY unsafe. The stocker are way to short as well as not strong. I see guys using them, but they are crazy doing so...I know my life and my car is worth more then a few bucks for the correct parts:-)

More then likely, your not going to get the closed lugs and the longer studs on with your z06 rims.

Those longer arp (2.5 inch studs)actually have a thread of 2.03 inches.

Here's what those studs will look like on stock sized rims...not much else you can do with them.

Thanks for the info Steve... I was using Draglites to do the fitting. Maybe with the prostars I will not have to use a spacer. And as said before the tires were rubbing the bumpstop with out the spacer

Try cutting the bumpstops if all else clears or (if you've clearanced the rotors already)...that should be a pretty simple solution instead of using the super long studs with the spacer. You probably can just trim the corners of the bumpstop a bit, you still will need longer studs though.

if its rubbing, then you got the wrong backspacing on the rim. all i can say is that i have ground 3 or 4 sets of calipers down for 10 inch prostars and draglights and never had to take the bumpstop off.

do you have 7.5 inch backspacing on the wheel?

Here's an oddball question, could he run spacers on his rear Z06 wheels so that the studs don't protrude as far out? I'm not sure how that would affect handling and the like...
