Back story: I needed new tires on my red 1999. It was hard to find the sizes I needed, especially the rears, 345/30/19. Well, Nitto had that size but that's what was currently on the car and my opinion of those was that they kind of sucked. So I got my favorite brand of tire, The Michelin Pilot Super Sports (Gawd, they were expensive). So as I'm putting the now mounted tires on the C5, I noticed they are wider than the Nitto tires were even though they were both 345/30/19s. Wider enough that they would easily hit the inner liner of the wheel well. So I ordered 1/4" wheel spacers and now I "think" the tires won't rub on the inner wheel well. But, when I put the spacer and the lug nuts on, I noticed that I'm only getting 4.5 turns on the lug nuts. I have read in a few places that they need at least 6-8 turns strong. So there lies my problem:
I've did some research but come up with conflicting answers.
Does anyone know the length of the stock wheel studs? I need a set that are a 1/4" or 3/8" longer. Place to get them? Part number? Any help would be appreciated.
. I forgot to add that I did raise the rear end of the C5 on the stock bolts another 1/4" to be safe. I'd HATE to crack a rear fender.
Big THANKs guys. You provided me exactly what I needed.
I've read the front studs are easy to swap but the rears are a PITA to do so taking it to a mechanic.

The rears are a lot easier to do if you cut a hole on the backing plate/dust plate. There's video and texts showing just what to do. Yes, the fronts are easier no matter what. Bit after that hole is made in the rear, the rears will be just as easy as the fronts from that point on. Hope this helps you out.
I'm pretty certain those are just "re-branded" Dorman studs. They're identical to the ones I bought for much less at Rock Auto.
Knewblew, have you considered trying a 3mm or 5mm spacer instead? Poke less and might give enough tub clearance without going through the expense of having a mechanic swap out studs? I ran 5mm spacers on stock studs with my 19x13 345/30/19 R888s to get them to clear the tub as well. Got me enough turns and I'll just say they were put to an extreme test and had no issues at all
