Default Trying to fit concave wheels onto the C7?

Hi,
So I'm currently looking at getting some Volks G25 wheels for my 2015 BUT it seems that the only ones that will fit the car are barely concave due to the high offset on the wheels.
But I could swear I've seen people with concave wheels on the C7 so how do they do it?
Thanks in advance!

There are some Cray wheels (TSW) that have a small amount of lip.

Or... you can go smaller and let them stick out of the fenders! (The Ricer Effect.....)

My car has the Forgeline SC3C-SL's. 20's up front and 21's in the rear.
Not much concave.
My advice is to call Ben at WeaponX.

Thanks!

I have a few styles like this that are deep both front and rear. These are a duoblock but can be done in a 3pc as well.

360 Forged Wheels
-Monobloc Straight 5 wheels
-19x9
-20x11
Michelin Pilot Sport tires
-255/35R/19
-305/30R/20

Options:
-Concave spoke pattern (cost a few hundred more, but the amount of concave is very limited due to the clearance needed for the factory big brakes on a C7)
-Clear coated (inside and out)
-Brushed aluminum finish (inside and out)
-I used FACTORY GM TPMS (not the cheap aftermarket ones)

The cheapest company offering 360 Forged I found was in Miami (305) 7 6 1-9 6 3 7

Wow they do look very nice, I am seriously considering the C7 spec ones but I do have a few questions about them if you don't mind answering them.
I can't really tell from the pictures I've found but do the spokes ( forgive my poor wording ) go out from the center and bend back inside towards the lip? It is really difficult to tell from most pictures I've seen..
Alternatively I would always appreciate more pics :p

These are the wheels that Rays Volk make for the C7. The spokes do indeed go out from the center and then back to the lip. Here, I've just taken some photos that might give you a better idea.

They look beautiful but at the same time I can't decide if what I mentioned would be a deal breaker for me how about the rears? I believe those would have more concavity ?

DONZ Yakuza's on my 2014. I wish they had a deeper curve, but as you know we're a bit limited. I like, no LOVE, all of the above wheels. Those WeaponX's are KILLER! Good luck with your search!

Just remembered this picture from a very loooong time ago I downloaded onto my computer and these wheels are absolutely beautiful... Doesn't look like there's wider fenders on the car either.. Does anybody know what wheels those are?

Nevermind looked them up they seem to be forgiatos ( quite heavy )
So it seems it's either HREs which would be unbelievably expensive or if I want to go below $1000 each the G25s are my best bet

Ugh... Most of these wheels are ugly or boring. I plan to go widebody fairly soon so I can get the more aggressive offsets and larger tires.

I have Rennen M5S monoblock forged wheels (concave) on my C7 Z51.
10x19 front, 11x20 rears.

I'm a huge concave fan... done it right on all my past cars (Euro's/Imports) but this C7 is extremely difficult to work with.

I have been looking for over a year, and my conclusions are:

The best concave can be had from forged monoblocks from the likes of 360 forged, Forgeline, HRE and Strasse wheels. Any non-fully forged wheel (pressure cast or flow formed) will offer minimal concave unless you push the wheel outboard a bit past the fender, like 11's with et. +65-70 in the rear. This is because the face is cast with a preset concavity to accomodate high offset cars.

On the C7, forged is the way to go unless you get aggressive offsets on cast wheels, like the new Vertini wheel which is decently curved. I've looked at the Volks long ago after having many in the past (TE-37, GTS, etc) but like the poster said, they curve out then back in giving the illusion, but i don't want that.

Here are a few forged (the red is the best looking I have seen):





Here is the best cast wheel i have see: (flow formed barrel/cast face):

I am looking for forged wheels mainly because I live in a place where the quality of roads can be compared to that in a third world country ( yep that's LA ) so I would not want to risk breaking my wheels.. I also like to go to the track at least once in a while so basically the sturdier they are the happier I am.
Also need them to be lighter than the stock wheels otherwise I can't justify spending that much on wheels

Vertini wheels.

Go in. The general section and search "Vertini". They have a thread with details.
