I've been looking at brake pad options and was set on the Pagid line from the reviews here. I purchased a set of the RS-56 pads for the rear and was considering the 29's for the front. I did see some new Hawk pads on Tire Rack that were designed for street cars that do track days and the price is half the cost of the 29's. Anybody have any experience with Hawk #HB453R.585?
