Car looks gorgeous.
I just got my 315 GS-D3's mounted on 10.5" Cobra wheels as well (with the 1/2" spacers), and the car looks MEAN! (I also have the 275 GS-D3's in the front.) I had 285 GS-D3's before, and I love that tire so much that I won't even consider anything else. I rarely have a hard time hooking in 2nd gear now (with minimal tire spin). I also have full-length subframes, IRS bushings, and a diff brace. In my opinion that is the BEST tire one can buy for these cars - the tread looks aggressive, it plants these cars down, and it is an incredible rain tire. They may be a little pricey (especially the 315's), but it's so worth it.
Those pictures are very crisp and clear!
