Default Forgestar CF10 on C5

All,
How many of you guys are running the Forgestar CF-10 rims on your C5. I have search for a while on here and on the webs with out much luck but then again I'm apparently not smarter than the search function.

What I'm looking at:
19x9 50mm offset front toyo r888r 265/30/19
19x11 54 offset rear toyo r888r 305/30/19

You can't get the CF10 in a 18.

I know someone will say use the F14 but I don't like it. I do like the CF5V too.

Any pictures or experience would be awesome.

Have you considered the F10D's? Run a 19x9.5 w/+50 offset on the front and a 19x11 w/+54 on the rear.
Just another wheel option.

The CF10's with the specs you posted would work well. So would the CF5V's.

Here's a really good deal, if you are close to the seller. https://www.corvetteforum.com/forums...and-tires.html

Mine are 19" front 275/30/19 and 20" rear with 305/25/20 tires. I would probably go with 19s at all 4 corners if doing again. Here are some pics:

WayneCar,
Thank you for the pictures. Your car looks awesome. Love the look of the rims. What offset did you go with? Any issues with rubbing or full wheel turn?
Did you do semi deep concave in the front and deep concave in the back?

Thanks, much appreciated. No issues with rubbing or fitment. The fronts are 19X9 and the rears are 20X11. The off-set is not marked on the wheels, they were just marketed with "C5 Flush fit". Yes, the front
is semi and deep for the back. I don't notice the difference visually though.

With those widths, the offsets are probably around +50 in the front and +54 in the rear.

Yes, I think you right on target with those numbers.

WayneCar,
Again thanks for the info. I think I will do the 19's all the way around. What tires did you go with?

why??
the 1" difference looks great and keeps the electronics happy w/o having to have different sidewall heights. Equal size rims just look wrong to me on C5 especially - the smaller rim in front goes well with the low low nose and the extra 1" looks good on the fat rear.
Car looks great!

I agree 100%. The C5 body was designed to utilize the different size wheels and tires. The front wheel openings are a smaller diameter than the rears. Regardless of the sidewall heights of the tires used to compensate for overall diameter, when running the same diameter wheels front and rear, it visually makes the front wheels look larger than the rears, if that makes sense. Not too bad, but just looks much more balanced with a staggered wheel diameter.

If you run 19's all the way around what will it do to the electronics?

As long as the tire diameters are right, nothing.

I'm going to run a 30 sidewall on front and rear because they don't make a 25.

When I purchased my car, it had 19x10 and 19x11's with 275/30/19 fronts (25.6" tall) and 295/35/19 (27.1" tall) rears. Now, it has 18x9.5's and 19x11's with 265/35/18 (25.3" tall) fronts and 305/30/19 (26.3" tall) rears.
Will be installing 325/30/19 (26.7" tall) rears, when I go widebody.

Looking at your numbers if I run a 30 sidewall front and rear I will have about 1 inch difference between front and rear with 19's all the way around.

Just depends on the tire sizes you choose.

Sounds like a good plan, KT. If you haven't already ran those tires before, just be aware they are really noisy.
