I just bought an awd and want to go with 20's. Any suggestions on factory swap? I see that the offset needs to be large positive. I tried my 9.5" SRT rims on and they stuck out past the tops of the fenders. 9" almost the same. Anybody think 8"s will work ok?
The ideal positive offset would be 40-42mm. Some say a 35mm would also work (see photo, below). If your car is still under warranty, I would check with the dealer before you make the switch. It may void it. Also, you should be aware that the ideal tire width on an 8-inch wheel is 225 or 235. The maximum that you can use for it to perform and wear properly would be a 245.
I have an SXT Plus and I bought new wheels from Merrick Motorsports. I'm currently running 275/40/20s in front and 315/35/20s in back. Love how it looks.
Check out tirerack.com. They show a bunch of 20 x 8.5 wheels for the GT. Like SRT Tom stated, the average offset is about 40mm. I would think a set of OEM 20" wheels from a SXT Plus RT Plus would work.
I think AWD all have the large + offset. Any 2wd factory rims will be 20 or so. My Durango rims would probably work if they had the right bolt pattern. (they don't)
