Wow you're right. Would on of those hub centric rings help?

You can get them here ....custom cut from billet aluminum.

I checked that out. A lot of bad reviews on his service. Nobody complained about the product just his service. I live in Sacramento and visit Reno often. If I can get there on a weekday, I will stop in and see about getting some in person. Unless I can find them elsewhere.

How thick of a spacer can I go with before I have to change the studs? Thinking of adding a spacer to the stock wheels to get them out a little more. Maybe a 1/3inch.

I was told no more than 3mm

I had no problems. If he says 4-6 weeks, just dont expect 1-2 weeks. He makes them on order so you get in line. I had my hub spacers in a few weeks but the custom made hub rings took a few weeks more. I didnt trust the plastic hub eccentric rings that came with my new rims.

fyi ... industry std calc for required lug tightning length for 14mm x1.5 = 21mm Make sure you have at least 21mm of stud left after mounting the spacer in order to fully tighten the lug 6/7 turns .
If you don't have a least 21mm of stud length with a spacer you'll either have to add longer studs or go with an adaptor instead of spacers

Our std thread length is 28mm, our stud size is 14mm x 1.50. I was able to get around 9 turns of the lug with a 3mm spacer I used ( I could have gone up to a 5mm if I wanted). 100% of the torque is achieved at the 6th turn, the extra turns don't add anymore tighting/torquing

After you place the order call and ask for Lenny ( the prop) and ask him if he can expedite your order. I got mine in about 5 days.

You would actually want about 9 full turns to be safest, the nut should have the same number of threads as equal to stud diameter which with a 14mm stud comes out to about 9 full turns or so.

I ran a 5mm on the street with stock studs, but put longer ones in before I hit the track since I only got 7 full turns. It might be possible though with a 3mm spacer and the longer truck studs the stock lug nuts won't work. With a 5mm I suspect the oem lug nuts are very close to bottoming out on the stud.
