Rim measurements

[Blackbeauty]

Hi guys,
With all these measurements and stuff on different websites, does anyone know what the measurements would have to be to have super concave 20's for the rear and super flat for the fronts? All I have to go by is pictures that are listed on the sites and a lot of the times they just use stock photos regardless of the "concaveness" and just list the measurements like backspacing and offset and stuff. So does anyone know what the numbers would be to find these things I'm looking for in a rim?

Thanks!!

What wheels and from there we can figure out how concave we can go. Every wheel and company is different.

Oh really?? I didn't know that. How about for some Forgestars???

Forgestars!?

Great bang for the buck wheel, both sets are the same 20x9 275/35/20 20x11 (deep concave) 315/35/20.

I like those a lot!!! You don't happen to have a picture of the rear on the black handy, do ya? The rear on the red don't look as concave as I'd like but what I can see from these pics, the black is more concave. For my set, I'm looking for a set that has a huge DIFFERENCE between the fronts and backs. If that makes any sense lol.

the main issue with concavity on the rear vs the front is the way our cars are setup from the factory. the front is designed to run a lower offset wheel(which gives more concavity in theory) and the rears have a very high offset by comparison(usually much less concavity)... for my setup I wanted it to be as much concave as possible on front and rear, and I opted for a square 10.5 wide et30.

my front is a tight fit, but my rear has 1.5" of room on the inner before I have issues, so in theory our cars want to do the exact opposite of what you want. thick pad height with a flat front wheel will give your desired look, but the rear will be tricky because in order to get a dramatic concave face, the wheel need a lot of depth from the lip to the pad, forcing a "flush" or "poke" look, regardless of the inner clearance.

in my experience, a 10-11" wide front with et30-45 will be about as much wheel as you can get under there, and the rear will be 11-12" wide et45-50...and that's with 1.5*+ of camber, which is too much for some peoples taste.

youre going to need a custom setup, and the wheel manufacturer will be able to tell you how their faces vary for et and concavity.

The two sets are identical, color / angle / lug nuts must make the black set look more exaggerated.

Here are a few old pics.

GuardGT's explanation helped clear things up a lot for me. I love that color on your red one. I think I'm gonna order a set of the Forgestars 5 spoke rims. I was really hoping to go for something like this
