Default Concave Wheel Options?

Anyone have an idea as to where to find concave wheels for our cars? I would like to do 18x10.5 and I am having a hard time finding wheels that are concave. I read something about the high offset making it hard to have concave wheels; is this true?

Any help is appreciated!

Edit: Looks like Forgestar are the right price and very much what I'm looking for but it seems there is no 18x10.5 but I've read 18x11 will still fit in the front?

Edit: Curious as to what people do to protect fenders and doors when running new wheels? Will 18x11 be flinging rocks into my doors and skirts?

Those are beautiful wheels. They seem to start in the 19 inch range though... And $1300 a wheel is a bit more than I would like to spend

Forgestar F14 Deep Concave. That's the ticket.

Do a search. There is a fantastic C5 thread about these wheels. I had them on my C6 GS. Very high quality. Definitely getting a set for my C5.

I saw those! Very much like what I'm looking for though I'm curious if the 18x11 would fit up front as that's when they actually start to look concave.

I was also looking at Cray but then I would have to get the 19 since the 18 isn't nearly wide enough

Thanks! I'm gonna check those out

Now I gotta figure out if 18x11 will fit up front. And hopefully I can do a trial to see if my nannies are sensitive to a sq. set up.

You won't be able to do a deep concave wheel on the C5 without wider fenders. The Corvette offsets are simply too high for it.

FYI, running the 275mm front tire with a 305mm rear will cause the front sidewalls to be thicker than the rears. It will obviously be functional, but will look extremely odd.

I have 245/40/18 fronts with 305/30/19 rears and it doesn't look out of proportion or odd. I believe the 245/40 even has a few mm more sidewall than the 275/35.

Not square and not really close to what I want. I see no need in different sized wheels.

I am beginning to notice this, but I've come to terms to accept this for the most part. https://www.corvetteforum.com/forums...ic-thread.html from what I see his rears look to be the right concavity. Sure it could be deeper but that's the high offset for you.

The rear looks pretty nicely concave I could live with that. Just gotta make it happen on all four.

I'm sure someone's running 18x11 all the way around that can put up some photos. I do like how the CF10s look more concave because they go immediately in rather than curve into the hub. But I don't know if I want to do a 19inch wheel...

Are C6s able to fit wider wheels than the C5 or is the overall width and offset similar?

The base C6 uses a HIGHER offset out back and roughly the same up front. The wide body factory C6s use lower offsets but the rear won't be as low as what a C5 with 2" flares can run.

I'm running Sport Muscle GS wheels with the C6 Z06 offsets. 19x10's with a set of 275 30 19's up front and 20x12's with 345 25 20's with 20mm adapters out back. They have a deeper concave than the factory GS wheels.

Looks like the CF10's offer more offset options than the F14's but the con is it doesn't come in an 18. I'm assuming that (like many concave options) a certain face fits a multitude of sizes. I.E an 18x10 will have the same concave as 18x11?

I'm still looking for conformation if the 18x11 55mm will fit up front.

Thoughts on appearance are obviously based solely on personal opinion. However, having a taller sidewall in front than in the rear looks absolutely ridiculous to me. Especially considering the car is RWD.
