Help! Will these fit
I am looking at a set of chrome wheels for my c6. They are z06 replicas. I am just buying new wheels, not tires, I am keeping my tires. I need to know if these wheels will fit my tires. I have 18" tires in the front, 19" in the back, and I have the factory polished wheels right now. Here is the specs of the new wheels:
Front- 18x9.5 with +54 offset and 7.38 backspacing
Rear- 19x11 with +64 offset and 8.52 backspacing
The bolt pattern is 5x4.75
It says it will fit any corvette from 1998-2010, but if anyone could tell me for sure I would be very appreciative. I don't know much about things like this so please help. Thanks

Okay thanks for all the advice! So these 100 percent will fit on my tires? I just want to make sure before I buy them because I don't want to get them and then them not fit. What about the difference in Offset? Does that make a difference?

Uhhh, am I wrong that these will stick out from the body and look ignorant because he does not have a wide body. Maybe they are Zo6 replicas for the base C6?

The offset will change how far the wheels will stick out pass the quarter panel and fender.
The offsets on the new wheels are lower, BUT the rims are also wider, so they may still protrude more inside and outside.

I just did some quick calculations. The width of each wheel is being increased by 1/2 inches each direction from the centerline (an effective increase of 1/2 inch more out from the fender. The offset is also being decreased by 15mm in the rear, which is ~0.6 inches, moving the wheel further to the outside. So you will effectively be adding an inch more wheel <---- Sounds funny, lol.
However, I could be totally wrong. Someone please confirm this.\

If they say that these will fit both C5 and C6 then they are probably a C5 offset....which will fit a C6, but the rears will stick out a bit more. These CRAYS have the C5 offset, and although I like that the rear tires fill out the rear fenders better, I can never go to a wider tire than stock:

I just double checked my calculations HERE and it looks like I was spot on 
As for looking weird, plenty of guys (and gals) have done it, and it really doesn't look weird at all. Its just personal preference.

His are the exact same size, and just about the same offset (+55 & +62)
I think it looks nice, but others may not.

Here is what my calculations show (they pretty much confirm what Divvi said....)
On the front:
The new wheel at 9.5 wide and a +54 mm offset will wind up being 14.65 mm or 0.57" more outbound than the OEM setup.
On the rear:
The new wheel at 11" wide and a +64 mm offset will wind up being 28 mm or 1.1 " more outbound than the OEM setup.
I think you are on a fine line here - the fronts moving a 1/2" or so outbound might be acceptable, but the rears at more than 1" might be a bit much.
You can easily see what this would look like by holding a straight edge ( like a wooden stick) about 26" long across the face of the tire while on the car. The inside edge of the stick will give you an idea of where the OEM tire sits in relation to the fender edge. From there just add a 1/2 " for the front and 1.1" for the rear to imagine where the new wheel would wind up in relation to the fender.
Again, I don't think you have 1" of extra room under the rear fender - the new setup would probably "stick out" beyond the edge of the fender - personally not a look I like...and I have heard stories of rear fenders being cracked by a wheel that was "sticking out" while going over a hard bump.

I did the same sizes on my C6 and they fill the wheel well nicely and do NOT stick out past the fender lines.

It's not the width, but the offest that determines if they stick out or not. If your setup has the same offsets as the OP mentions in his post, then all is good - but based on the info provided the rears look suspect....
