Interesting comments on the issues. No arguments from me on your position. I've seen the stock PBR parts toasted, but it was some time ago and perhaps there have been improvements here. I don't much see the dust boots being that big a deal, but it comes up. I consider all the calipers run in weekly racing which are not sealed in this manner from many manufactures. They, like on my own car in the dirt, hold up just fine. I can't comment on what is legal in calipers. I understand your position, but I'll also bet that I'll find Zenon bulbs, euro lights and cat -less exhausts etc. that you may sell that carry the same results. I selll the Wilwoods as racing applications, and the disclaimer of warranty and use up front and open. This is further stated on the calipers from Wilwood. Like any aftermarket part, it's up to the purchaser to determine the suitability of the purchase to his local codes, needs, and application.
