So do your wheels fit flush to the fender now before they are widened?

I think this will turn out well for you.

Moving on, here are a few more shots of them together.

The soft contours of both sets of fenders seem to match well.
Sorry, just trying to understand your math...you're running a 1" front, and 1.25" rear flare, how does that equate to 2, and 2.5"?

I think with a rear 13" wheel, you're asking for trouble, and it may not fit and could encounter clearance issues both on the inside liner, and fender.

I'm running the CC 1" front with the CC 2" rear on a track setup with OEM C6Z wheels, and a 12mm spacer out back and they sit perfect...any larger in the rear even with correct backspacing would put me at the limit with a 13" and you're already losing width since you're running a 1.25" fender. Just my opinion...hate to see you do all this work and find out they don't fit.

X2. Total width increase front and rear.

Ah, got it! I'm still skeptical of a 13" wheel fitting without any type of clearance issues.

I was wondering the same because the 3" will have to be added to the inside of those Beautiful wheels, so it will depend what offset they start out with. I think you can get a 13" under there but the offset will have to be just right. I run a 13" under my flares but they're custom.Name:  photo623.jpg

This is why I enjoy the forum. I appreciate you guys helping in figuring this out. The wheel measurements are currently 19X10 +20. I am still trying to calculate the change in effective offset by adding width to the wheels, but if I were to increase them by 2 inches, I believe the result would be something on the order of 19x12 +45. Correct me if I am wrong.

Looking at those wheels they can only be widened at the barrel. You're going to have to figure out the spacer size you will need and not so much the back spacing. Best way to take out the guesswork is to take measurements while you're test fitting the fenders. I calculated one of my setups using lugnuts and washers and took measurements...in this case I needed to run a 1.25" wheel adapter on my 18*12 wheel, while both my forgestar and OEM C6Z wheel run on a 12mm hubcentrix spacer. You're going to also have to get longer wheel studs.

I will be shooting a vid later in the week to explain the C5 foot print with flares...hope this helps

325/19 wheel. I am not sure I understand why you need a 12/13
wheel. A 11 or 11.5 wheel will fit nicely.
Good luck.

Minor Update

I test fitted the wheels on the car with the stock fenders just to take some more measurements and to see where I stand. While this is not a true indication of how it will look in the end, this fitting has shown a few things: First, this wheel fitment combo is going to be quite "aggressive". I imagine there will be a slight "poke" (is that what they call it these days?) which can be corrected, some what but not fully, by altering my camber settings. Either way, I am ok with the look although I know many see it as "tuner" or "stupid". I make no apologies for it. And second, I think it is going to sit very nicely when it is all said and done. Anywho, onto some pictures.

As you can see, the wheels do protrude past the stock fenders. That goes without saying. How far they go past, however, was a touch more than imagined.





This is a bird's eye of the front wheel. It protrudes past the fender by approximately 1.2". Should look nice with the CC 1" replacements.



This is a bird's eye of the rear wheel. It protrudes past the fender by approximately 1.7". A bit more than the L5-R's may allow but workable. Worst case scenario, I move up to a 2" flare in the rear.


For those who were expressing concern about widening the rear wheels too much, there are almost exactly 3" of clearance to the inner fender, so going to 12" should not be a problem. Here are a few more pics.









That's all for now. Hope to have the wide fenders and quarters test fitted and off to paint in the next two weeks.

The colour of the wheels goes nicely with the colour of your car. Have fun, and good luck with your project. I look forward to seeing the finished product.

Fronts look good, rear may shoot passed the 1.5"....not the end of the world, just be careful if you're lowered

Something to keep in mind about rear fitment...The area where clearance runs out first in the rear is about halfway up the front of the wheelhouse. It's that front, inside edge of the tire that will contact before anywhere else. I tried to get a pic on my car, but it was too low and too dark to get a good one. I occasionally have a very slight rub there. It's so minor it barely marks the fender liner. My wheels are a 19x12 offset is +73. Tires are 345/30/19. You can do some math to figure out your offset change as your wheels get wider.

Your pictures answered my question about your current offsets. You can definitely add 2" to the inside of those wheels. 2" rear flare might be a good idea. It's going to look great!
