rims dont fit?
i had ordered some c6 z06 rims from fast toys performance, they were o e concept rims. they are all 17x9.5. The fronts were extremely tight to whatever arm comes like almost straight up, like i couldnt even fit a finger between the rim and that, which idk if thats normal or not. but my main problem is when i put the rims on the back, the hub that actually protrudes through the center of the rim when put on seems to big for the rim. Fast toys says that from 93-96 the hubs were bigger then later years and i should try and grind the center of the wheels bigger to fit, and if it didnt work they would take the wheels back. wtf? why would they take them back after i grinded on them? anyone ever heard of this? sorry for the long post

Yes, LT1 cars have different sized hubs vs the LS1 cars and vise versa, but I thought that they were all built for the larger hub diameter?

haha yeah i ran into the same thing. i just took a die grinder to the center of my rim till it fit. the lug nuts center the wheel so no worries. watch out for the bump stop though, i had to cut it off with my 10.5" rears.
98-02 fbody wheels are the same when installing on the rear of 93-97 cars.
i wanna see them!!!
btw

I would not suggest "grinding" a wheel to make the hub fit. That requires actual machine work to be done properly and ensure that the wheel sits properly.

no, the inner diameter of the wheel hub is small for ls1 rear end application. lt1's need to open the center up just a little bit for the wheel to fit on and come off easily. the lug nuts center the wheel on the axle. no worries whatsoever.

Hence lug centric wheels

Street or track, having the wheel supported by both the lugs and the hub is vastly safer than just laying it on the lugs and hoping it is sitting properly. Hub centric also keeps the wheel centered properly in case a lug falls off.

Send them back and order the correct size for your hub. If they don't take them back then have them machined.

Early 4th gens larger slightly larger hubs, and 93's and early 94s are even a bit larger. When I put the SS wheels on my 93 I had to do some gringing. You're talking very slight! Nothing that is going to result in the strength of the rim. Just take your time and take off only what is needed to get the rim to sit flush on the hub.
I've run my SS rims for over 10 years with drag radials, broke all kinds of driveline parts, and the rims are still good! I just bought 17x11s and they will need to be tweaked as well.

i took my drummel with a sanding drum, and just went around the inside real quickly. nothing major like Pampered said.
Funny thing is ... the 01-02 speedline rims fit on my LT1 no problem. The 93-02 WS6 rims needed grinding. Go figure...
