I was just about to ask the same question. Does the 1.6" drop of these springs in front cause problems with the stock wheel/tire setup? I've heard Bell Tech (2") springs require a lower profile tire, but I assume the problems occur with the rear tires.
I'm running H&R springs and have had no problems with rubbing or anything of that nature front or back. I am currently running 275/40/17s, but have used the stock-size tires as well as 20 inch wheels and tires (20x8.5front and 20x10 w/ 255/35 and 285/35) with no rubbing. They do lower the car quite a bit and with the 275/40s I can no longer use my floor jack without using ramps first. The factory jack fits just fine though. $285 is a little high. I paid around $200 at the tirerack, which had the lowest price of any place I called. www.tirerack.com
