Correct offset for wheels to sit flush?

I don't want the wheels to stick out past the fender at all. Am considering going to an 11" rear wheel. What offset would I need to make it flush?

I'm clueless when it comes to offsets and pretty much anything wheel related.

I had my SVT wheels widened to 11"... I think they started out at 7.25 backspace, so I must be around 9" offset. They fit a 315 perfect. I had to remove the bump stop & shock boots to make them work.

I guess I need to convert that to mm. I'm thinking about ordering new wheels, and would like to know offsets before I do. Thanks though!

I have Forgestar F-14's. My 20x11 rears have a +55mm (2.2") offset. I'm running Nitto Invo 315/35's and they sit flush with no problems.

Mine are 20x9.5 and 20x11 with a 295 tire out back and a 255 in the front. The offsets are about 28mm front and 45mm on the back. They are as flush as you would want to try offset wise. That's the reason I am only running 255 and 295. :beer:

One of the best looking cars here. What's your brake set up it looks awesome.

I have the same set up as you ^ 20x11 with +56 os. IT couldn't be any more perfect. I actually don't remember what my fronts are right now. I think they're 20x9 and maybe 35+ os.

My math was a little off... I just measured mine & they are 8.5" back spacing & 11" wide...

for the rear, you want the wheel to extend roughly 83-85mm from the hub. TommyV and Justin81 are pretty much on point with their rears, with 84.7 and 83.7mm of extension.

to calculate, simply multiply wheel width by 12.7 and subtract the offset.

11 x 12.7 - 55 = 84.7

the front can go more aggressive offset (extending more than ~84 mm from the hub) depending on the amount of camber you're running.

This is EXACTLY what I was looking for! Thank you!
