98+ TA wheels on lt1? I've seen numerious lt1 body cars with the 5 spoke ls1 style wheels on them. I got a set of those from a friend and tried putting them on my 93 camaro. When they are on the lug nuts only catch 2 threads or so and then they are bottomed out. Obviously that wheel is thicker than my stock wheel .. but how do people take care of this? I'm assuming longer wheel studs? Or do they have the bottom of the wheel shaved down 1/2" or so ( where it sits against the hub ) to bolt them up?

They do bolt right on but it seems like the lug nuts don't screw down far enough to be safe. With my stock wheels the studs almost come all the way through the lug nuts. With the LS1 wheels not even 1/2 way.

The hubs on the rear are different for 93-96 cars. They are a little larger then the 97-02 rears. What you need to do is grind a little to make room for the wheel to fit. It's only for the rear, the front should be fine. If you do a search, you should be able to find out how to fix the problem.

I found this on another forum.
WHY WON'T MY NEW WHEELS FIT OVER THE REAR HUBS ON MY 4TH GEN?
The 1993 to "late" 1996 4th Gen F-Bodies have a larger hub on the rear axle than on the front spindles. The rear axle hubs are about 0.03" larger in diameter than the front hubs. This problem was corrected in late 1996 model year or possibly in early 1997.
As a result, if you buy C4 or C5 wheels, or if you buy 1997 or newer F-Body wheels, they may not fit on the rear hubs of your 1993-1996 F-Body.
The solution is very simple. First, DO NOT FORCE THEM ON WITH THE LUGS! Very dangerous, and you may not be able to get them off. You need to lightly sand or grind (e.g. - Dremel) the inside diameter of the hub hole in the back of the wheel. Don't go nuts.... just remove enough metal so the wheel cleanly fits over the rear hubs, with no interference.
Think about doing this to all 4 wheels, so you can "rotate" the tires in the future.
This will not harm the wheels.... you are taking off the thickness of a sheet of paper. Just be sure you do a neat, smooth job. This will also NOT affect the centering of the wheels on the hubs. The 4th Gen wheels are "lug-centric" - they are centered by the conical lugs, not by the hubs.

I did this recently, but I ground on the hub. This way I only had to grind on two things, but I can rotate my wheels. Also, if I have a problem with any of my wheels, they are still under warranty. I didn't have to grind much off, just enough to get to clean metal.
