I got my new 19x8.5 Konig rims (30 offset) put on with Continental 245/40/19 tires all the way around. I wanted to see how the car looked with the rims before I ordered either coilovers or lowering springs. I noticed that the car sits about an inch lower in the back than in the front..any way that I can correct this? All of the suspension is stock. This is a 2007 G35X Sedan.

 

Your car is fine, the fender arches, are cut differently, the front is about 1/2 inch higher than the rear. If you have a perfectly level spot you can measure from top arch to ground, (front and back) and those measurements should be the same on both sides. The 2nd gen cars were all made that way, (especially the X cars) They just have that reaching for the sky look, however, they still are very quick, competent sedans, that can do it all! These sedans are pretty easy to lower, ( I lowered mine with just Eibach springs in 2009, and kept it that way for about 9 years, loved the look, did NOT like the ride, so put it back to stock) I also have a summer set of tire and wheels, ( 245/45/18) On OZ Ultraleggeria's 18x8.

 

I had the first gen sedanX, and my understanding (didn't personally try) is that it was NOT easy to lower because the relative rarity of the AWD models they had much less aftermarket support, and just because the front end dynamics are very much different with the AWD configuration. I don't know if that changed for your generation.
