what size weld wheels?
Hey all,
I have a 96 LT4 (see sig below) and I am considering purchasing the following from a board member:
Rears (15x9) (Weld XP Prostars) (5.5 backspacing)
Fronts (15x5) (Weld Prostars) (3.5 backspacing)
He had them on his 87 C4 and had no problems with fit. I'm pretty sure the rears will clear (and I don't mind grinding the caliper a bit if I have to) but my concerrn is is the 15" clearing the front brakes.
Any thoughts or experiences?
Thanks!

I'm not positive, but I think you'll need more back spacing. I have 15 x 10 with 7.5 backspacing. This is on my '93 and what most of the others are using. Also some guys are using a 5/16 spacer as well.
The fronts should be OK, I have 15 x 3.5

Mad,
on my 89 I use 7.5" back spacing + 5/16 spacer and had to grind the calipers.
On fronts I have the J55 bigger 13" brakes/calipers and used also a 7/16" spacer + ground the calipers.
But I don't use the XP's. Maybe they are different.
I think I saw Beachbum Todd use XP's at the track one time. Maybe he will chime in here.

The fronts are fine with a 5/16" spacer for the larger 13" brakes. I think I an using a 7/16" spacer on mine with planty of extra clearance.

Re: what size weld wheels? (Vette92)
are you guys using longer studs? I have a pair of 15x10x6.5 draglites with 325-50-15 BFG's on my drag radial car....what are the chances they'll fit on my 90? Slim??

Use to have this same set up on the rear of my '94. Did have the longer studs in the back also.

Re: what size weld wheels? (AS84)
oh yeah. I forgot about those. I am using the ARP's. The nuts that were included with my chrome 5 spokes are open ended acorn. They just had a chrome plastic cap covering the end. I didn't know this till I bolted them on and bottomed them out on the rim. The stud came poking out. The lock nuts I had a machine shop lathe off the ends so I could still have that security feature.
Use GM perf part # 22551491 studs. They are the longest.
also, the spacers do need to be 7/16" as Chris mentions above. I will edit my previous post.

Paul- so your studs are cut off at the " just right" length that allows you to bolt your street wheels on, with the theft preventative locks, yet long enough to give the support that the weld wheel needs? I would really hate to change out studs and then have to do some funky mods in order to get my other wheels back on.
BTW- thanks for the info
