I got GS-D3's put on. 245 up front and 275's in the rear. What little driving I've done feels fine. They hook up really well, which seems to have made wheel hop worse. It seems like they are really stretching the sidewalls in the back, so I'm guess they will wear badly. Here are some quick pics:
Front 245's left and rear 275's right.
This is a top down shot. I was actually a little further away with the 275's so in reality if I was the same distance the 275's would show more bulge
They look awesome from behind. Very tough.
