18" and 19" wheel question
Thinking about upgrading my wheels to something from CCW. My question is if you are running 18's on the front and 19's on the rear, are there any problems with rubbing? Are there any issues with maybe running 18's all the way around. I figured since I currently had 17's & 18's that moving to the 18's and 19's would be best. My car is currently not lowered. Any help and advice is appreciated.

you shouldn't have any rubbing issues. I've got that set up and lowered on stock bolts.
there are also 19/20 set up that don't rub

I have 18/19 with 245/285 tires - no rubbing or clearance issues and I'm not lowered. I think you should be able to go up to a 305 in the rear with no rubbing, but it might be 295.

as you go up per inch in wheel size you need to drop down per inch per tire size to keep the overall height about the same.
example:
stock rear tire on 18" is 275/40-18 would be on a 19" 275/35-19

stock rear tire on 18" is 275/40-18 would be on a 19" 275/35-19

I'm running an 18x9 with a 275-35x18 in front and a 19x10 with a 305-30x19 in back. My car is lowered on the stock bolts with no bushings cut. I have no issues with rubbing front or back. The rear sticks out slightly, but I like the look.
The factors that you must consider are rim width and offset. You can run a stock width wheel on the car, but if the offset is wrong, you will have issues with rubbing.
The tire sizes are a direct correlation to the width of the rim. Finally - you would want to maintain the stagger front to rear. The front is obviously a shorter height than the rear. You could conceivably run a same wheel size (18's all around or 19's all around - many here have that), but you maintain the stagger by carefully selecting the tire size (width, aspect ratio and height).
This is not overly complex but you must choose wisely. There have been tons of posts lately on this topic - I respectfully suggest that you might try a search.

Thanks for the info guys, I really appreciate it. I have put new wheels and tires on a few trucks that I have had, but a Vette is whole different animal and I did not want to screw things up. As always the forum members here are a tremendous help. Now I just need to swing by the CCW shop and get things lined up.
