Also posted this in the photoshop section, mainly because I blurred the background, but its the first of more to come. Tricky getting the lighting just right, I'l tell you. I didnt want my car to look like some of the really bad photographs running around in this section.
Pictures 2 and 3 give you some detail on my custom size Kumho Supra 712 225/55/16 tires... they provide about 60% better grip than the stock ones, and they ride firmer. The other interesting thing about my setup is that the smaller tire size increases the final drive ratio by 7%... moving power down to the low end.
