I am wondering if 20x8.5 et35 w/ 245/35 and 20x10 et44 w/ 275/30 will sit flush on a 2nd Gen. GS? Are the offsets too conservative?

 

I think they'd be just right , dunno about the rubbing though .

 

The fronts will be straight flush. I think the rears will still be sunk in just a little. I would have gone with 40 offset for the rear. What you have will look alright though.

 

The rear will just be sitting in a little bit. With the front set up u'll be running, 20x10 +35 will give u the flush look u want.

 

How low is the car going to be, thats if it's going to be lowered at all. I say this because the lower the car is the more camber the car creates. And what will sit "flush" at stock height, will sink like a battleship when lowered.

And to me, having the wheels sit flush to the fender means rolling or cutting the fender inside fender lip.

 

If you really want flush, fender mods will be needed. If you don't want to cut, then aim for almost flushed. At +40 (and a 275/30 tire), you might have to trim the fender SOOOO slightly depending on the tire shape. At +35, you definitely will. At +45, you won't need to trim but it won't be flushed.

 

Thanks for all the responses. I am currently running the Tein CS v2 and I'm at a 2 finger gap all the way around on the stock 17's. I think what I am aiming for is to lower it down a bit more at the point where I do not have to run negative camber just to "tuck" the wheels. I think what I am aiming for is a +40 offset then. I don't really want the wheels to be inset. But I'm guessing that I will probably do some slight fender work anways. I know the tires would probably rub anyways on hard turns or bumps and involuntartily tuck itself.


P.S. What offset would I need on a 9.5" wide wheel to be equivalent to a 10" wide et40?

 

You might not have to. When you run 20s with those tire sizes, the wheels are about 1" bigger in diameter. This means you are about .5" closer to the fender.

+34

 

Let me show you my old set up.

These are 20x8.5 and 20x9.5 with +35 on both, running on Dunlop SP9000 245/35/20 and 285/30/20. I think this is a nice set up for sitting almost flush.
