I can gaurentee KW will honor the warranty and replace them if I have an issue. Coilovers are meant to be tracked not babied imo so I doubt that would prevent them from replacing them. I'd call it track use not abuse. I don't even know how many times they were brought to the track but if KW coils can't handle normal track use, they shouldn't even be considered high quality coils.
