Are they a direct fit cause i can get a complete set of rims and tires for $200

 

Exactly what size C5 wheels? Standard or Z06? OEM or aftermarket?

The bolt circle is the same and they will bolt on, but the offset/backspace of the wheels determines whether they rub on anything, or sit too deep in the wheel well. The 18x10.5's are the most likely to be a problem.

We have a "Wheel and Tire" forum. I'll move this thread there.

 

Standard I Think 17 Front And 18 Rear

 

yes. have them on both of my cars 17 x 8.5 with 255/45-17 front and 18 x 9.5 285/35-18 rear.

 

how big of spacer would i need for the 18" 10.5 C5 Y2K rims to fit on a 00 camaro?

 

The only factory 18x10.5" C5 wheels were the Z06 wheels, with a 58mm offset. That's about an 8" backspace, and puts the inside edge of a large tire into the inner fender liner on many cars, and may require cutting the edges of the jounce bumper bracket, or recentering the body over the axle assembly with an adjustable panhard rod to fit them without a spacer. You could use a spacer, but anything over 1/2" would put the outside edge of the tire outside the fender. And it requires longer studs, unless you find an "adapter/spacer" that bolts to the stock studs, and provides a new set of studs for attaching your wheel.

There are replicas of the 2000 C5 wheels that are made in various offsets. A 50mm offset would be the best solution, since it would be under the fender and not too close to the inner fender liner.
