18x10 and 18x12 Work VSXX what offset???

[tagappliedfor]

i really want these wheels on my car, but i'm not sure what exact size or offset. i'm pretty sure that 10's will fit up front and 12's out back if i roll all four of my fenders, or at the very minimum 9's and 11's. but what offset?? the mustang in the picture appears to have the same size front and rear and it looks like it has plenty of room for more, opinions please? i plan on going one inch lower with my car to make them flush. i'm not worried about the tires hitting, i'll get them smaller (like 275 or 285) to make room if i have to.

Get something a little more aggressive than the picture you have. Those wheels you need it aggressive and slammed. Just my opinion.
I'm thinking fronts would be 45mm offset and rears ???

I had those wheels in black w/ polished dish on my M5, absolutely stunning! Every time I cleaned them they broke peoples necks. They are pretty light and look sick!! Not cheap though.

yea i know they look like all four are the same size. i guess i need to get it to a shop and let them do some measuring, if i can find someone that knows how to do that. they'll be about $2400, going for that hella flush look

those would look pretty dope honestly

Hope this is of some help.

Offset & Backspace - How Do They Relate?
Offset and backspace are essentially two different ways of looking at the same thing. They determine the location of the wheel and tire assembly when bolted to the vehicles hub.

Offset is the measured distance between the hub mounting surface and the wheels center line.

With X being the determined offset, the hub mounting surface on positive offset wheels is X amount forward from the wheel center line. The hub mounting surface on negative offset wheels is X amount backwards from the wheel center line. The hub mounting surface on 0 offset wheels is the wheel center line.​

Backspacing is the measurement from the hub mounting surface to the back edge of the wheel.

***Typically speaking, the higher the offset/backspace, the more the wheel will tuck inwards towards the suspension or away from the fender. The lower the offset/backspace, the more the wheel will push out away from the suspension or towards the fender.

For Example:

*If the offset on a 9" wide wheel is +12mm, the hub mounting surface will be 12mm forward from the wheels center line. Measuring from the hub mounting surface to the back edge of the wheel, the backspacing is 5.5"

*If the offset on a 9" wide wheel is -12mm, the hub mounting surface would be 12mm towards the back of the wheel from the wheels center line. Measuring from the hub mounting surface to the back edge of the wheel, the backspacing is 4.5"​

Here's how to calculate the backspacing using the rim width and offset:

First - add 1" to the rim width and then divide by 2 to find the wheels center line (you have to account for the wheel flange which is why you add 1" to the rim width) . Second - convert the offset which is in millimeters into inches. There is 25.4mm in 1 inch so divide the offset by 25.4. Lastly - add the converted offset to the wheels center line if the offset is positive for the correct backspacing. Subtract the converted offset to the wheels center line if the offset is negative for the correct backspacing.

For Example:

17x9 +12mm offset

*9" rim width + 1" = 10"
*10"/2 = 5" (wheels center line)
*+12mm offset/25.4 = 0.47" (0.50" rounded up)
*0.50" + 5" = 5.50" Backspace


17x9 -12mm offset

*9" rim width + 1" = 10"
*10"/2 = 5" (wheels center line)
*-12mm offset/25.4 = 0.47" (0.50" rounded up)
*0.50" - 5" = 4.50" Backspace​

***Please note that the wheels center line is the backspacing for 0 offset wheels.

^Definitely some good information to keep around. Thanks.

Those would look sick and definatley different

12s will be an issue unless you relocate the shocks

11's need to be in the high 50's if im not mistaken. I think Steeda runs 59 on the spyder.

The fronts with 10's needs to be around 45 i believe. Thats what Roush runs on the front of their cars.

The owner of the car in the pic is on this sight. Hell i remember the meet where that picture was taken lol. Too funny. Your going to need coilovers and probably run 295/30/20 out back maybe even a 285/30/20 and a 265/35/20 up front to hit the hellaflush look you are going for.
