is that track calipers usually don't have them because they are not neccessary with frequent maintenance, ie many race teams will rebuild thier calipers after every race, or probably at least every season. I would seriously question not having them for a street car where you can get brake dust against the piston for long periods of time. imo it doesn't matter what variety of SS they use, brake dust will corrode it eventually. if you plan on serivcing them every few months though I dont see eliminating them as a problem.
my major concern with the akebono kit is the diameter of the pistons. The way I understand it is that when stoptech designs their BBK's for a certain application they size the piston appropriately to the application to increase clamping force without changine the volume of fluid so that you get the correct bias and dont need a different master cylinder vs stock. being that the only engineering involved in the akebono kit is to design a caliper relocation bracket I wonder how much of a problem this is. Although I'm sure the same holds true for the AZ kit since they are probably just using off the shelf willowoods that wern't designed for a specific application. I'm also curioius how much heavier the akebono calipers are vs a stoptech or willowood equivalent.
