I might have to try the Porterfields next time around, I am not happy at all with the HPS and wilwood combo. I think the wilwoods are a good package but these HPS suck, I am having problems with a "shimmy" that occurs about once a week and basically the only way to get it to go away is the re-bed the pads. Not sure the issue, if the HPS are leaving deposits or what. It is an annoyance. Let us know how the Porterfields do in heavy rain, the hawks seem to loose thier bits for the first split second when driving in heavy rain, which is less than assuring in a panic stop situation.
