you bought the wrong car than

 

It's not known for being a sports car, in handling terms so targeting it is within reason. Bigger issue is a lack of resolve to avoid expensive sugar pill parts or to do what is required to effect real quality of change. Only then will they remotely come close to extracting what the platform is capable of and for that reason, yeah,......buy the audi.

 

Can we run the 18 x 8.5" 2007 G35 sedan Sport wheels all the way around on the 2006 G35x with 245/45/18 tires?

Wheel size: F: 7.5 x 18 in, R: 8.5 x 18 in
Wheel type: cast aluminum
Tires: Bridgestone Potenza RE050A; F: 225/50R-18 95W, R: 245/45R-18 96W

 

Since tires are 90% of handling and spring just hold up the body, the lightest smallest diameter that will fit brakes forged wheels and the fastest wearing soft tires you can find [something that lasts no more than 8,000 miles].

 

As long as the front and back wheels are all the same size. You can not run staggered wheels on an X. I am running 18x8.5in wheels right now (38mm offset) with plenty of room for clearance. Toyo T1R 245/40/R18s all around. So far this has made the biggest difference in handling. With the limited sway situation I am considering poly bushings in the front and Stillen sway for the rear ($180 for the rear bar from Stillen sounds about right.) Hopefully this will eliminate some body-roll. I also purchased some OEM sport springs from another member. Should be interesting to see how this effects the ride.

From what it sounds like, there is a lot of demand for performance parts for the X. I am surprised that a front sway bar is not available.
