I think these are the Lindsey plates (they look like them anyway). I looked at those before deciding to go the Racers Edge route. The digging I did suggested that the bearings don't last very long and you need to shorted the length of your front strut significantly such that they don't work with some adjustable suspension struts as they don't have enough adjustment to accommodate. I decided to go with RE as they were not that much more expensive ($350), were designed to work with stock non-adjustable struts (not really an issue as I was going with KW, but cerainly didn't want to be in the position where I was struggling to install them), and have a ridiculously highly rated bearing and couldn't find one report on any forum of RE camber plate bearings needing replacing.
A great mod by the way. I noticed no detrimental effect to ride quality and improved steering response immensely.
