Tire options are limited with 17. 18 is much better.
I totally agree that I will have a much better tire option with 18 inch wheels, and brake upgrade options too, but for my own personal taste I don't really like an 18 inch wheel on a 1st gen Camaro, (no offense anyone, that's just me), and I especially don't like the look of an 18 inch rally, especially for this particular car. I think the 17's don't look too different from the 15's, especially if I go with the Wheel Vintiques rallys, and I want as much sidewall height that I reasonably go with.
Yes a 245 tire will fit if you get the backspacing right and run a little negative camber.
Awesome. Don, if I stayed with my 15 inch rally's and put 245's on them, instead of going with 17 inch wheels, do you think that will fit up front, say a 245 60 15? That would give me an approximately 26.6 inch tall tire in front. Any rubbing or clearance issues with that? Or would I have to go with a 225 60 15 up front instead that is approximately 25.6 inches tall? (hope my math is correct on those sizes!)
I agree that 215-60-15's look too small. I had 15" rallys (7" front, 8" rear) and ran 225-60-15 front and 255-60-15 rear with no rubbing so I'd definately step up in size. Staggered fit looks good unless you want to rotate your tires then you'll be more restricted in size choice based on what will fit the front. You can see my 17" tire size in my signature below, wheels are 8" and 9" wide. That nail in the tire was a blessing. You don't want to be driving on 16 year old tires for any reason.
Cool. Same question to you as to Don, do you think a 245 60 15 would fit up front, or would there be some rubbing and clearance issues? The 245 60 15 is about an inch taller than the 225 60 15. If I stick with the 15's, then it looks like I'll be running the 245 60 15 up front (probably at all 4 corners), unless it won't fit, or the same size you used, the 225 60 15, and a 255 60 15 in back. If I go with the 17's, I'll run either a 235 45 17 or a 245 45 17 up front, and a 275 40 17 in the rear, which seems to be the most popular largest staggered combo for a 1st gen.
Great info and suggestions so far. Keep 'em coming!
If I go with 17 inch wheels, I'd also like to upgrade the brakes from drum at all corners, to most likely something like C5 brakes, with something around the size of a 12.9 inch rotor in front. I've heard a couple of people say that those will fit with the Rev Wheel 107 rally. Any feedback on those 12.9 inch brake rotors and C5 calipers fitting the Wheel Vintiques or the Rev 107 rallys?
