the collector

I know this has been asked 100 times. I cant find any thing on them and the sticky wasnt really helping me. I know people hate spacers. But my wheels are almost rubbing as is on the inside. And they are the 10 inch wide wheels. I want them to stick out alittle on the out side but not past the rear quarter panel. Who has this set up with wheels an what are you running for tires. And what are you running for spacers 1.5 or 1.25 inch spacers? They are 18s in the rear 17s in the front.
Thanks

Are the OEM/factory C5 wheels? Or aftermarket repro's? If repro, what is the offset of each size?

Odd thing is there were no factory 10.0" wide C5 wheels. 2000-2002 were 17x8.5 or 17x9.5 front; 18x9.5 or 18x10.5 rear. Z06 were similar sizes.
