20x9" wheel with a 30mm offset, will it fit?

[jimmyducati]

So, Im a huge fan of using "stock" parts to enhance cars and LOVE the look of the Saleen Mustang wheels but they only come in 20x9 with a 30mm offset. I used an online offset calculator and it said the wheel will be 4mm closer to the spindle and 16mm closer to the fender.

Has anyone used this particular wheel size?

Well, speaking for the Flex (but super-similar to the SHO), I think it will work but it will poke.  I have 22x9 +37's up front, 22x10 +37's in rear.  So the 20x9 +30 is pretty much like a 22x10 +37, just about 6mm more inboard.  This is a good calculator http://www.willtheyfit.com/ and you can check it out and compare.

Point being, for a square setup, the front will poke and the rear will look almost exactly right.  If you use 245/45-20's, it will probably still fit, but the tire will be slightly stretched.  A 275/40-20 may work in the rear, but in the front things could get dicey.

That help?

You'll be fine even with a 255 width tire if you choose to go wider. I have stock rims with a 1cm spacer and 255 tires and I still have some room to spare at the fender

Thanks! I'm not opposed to having the wheels turned down slightly and making up any difference in the rear with a small spacer.. I've done it before on much higher hp cars..

Let's do the math, we can get it exact.  So the stock wheel is a 20x8, and +39 offset, so adding 10mm would result in a +29 offset on a 20x8.  Now if he has a 20x9 +30 offset, that means he's got a 1/2" (~17cm) on you, on both sides.  That changes things a bit.

My math puts the stock wheel vs. this theoretical 20x9 +30 a full 21.7mm more outboard, and compared with the 1cm spacer said above, that's another 11.7mm more outboard.

That's why I said, it can be dicey.  That's not a small amount.

I don't consider the 1/2 wider rim to be an issue as it only stretches the sidewall of the tire out ...not the tread surface.

Here are my 20x9 30off-set with 275x40x20' Fits good

That's a good example of success. 

Pokes in the front though, right?
