They are extremely close and do fit, but spacers help. I have a set of with snow tires on my LS, I test fit them before I did a brake job and they fit fine. With new pads they hit the calipers. I luckily still had the old pads and was able to put those on and it fit. I bought some spacers off ebay, and I am going to get those put on soon, which will let me fit at least close to a new pad. One other thing to watch for, have them put on the car by the tire mounting place. I used Tire rack, and they use the tape on weights inside the wheels, not on the rim, and I didn't have the car with me to get them mounted, so when i got home, I had to move a couple weights to clear the calipers. This is only a problem with the front brakes, there is plenty of room on the rear.
