I had my Koni yellows on my Integra shortened and revalved half way through 2004. I've since ran 4.5 more seasons on them, and probably close to 60 races or something, without touching them again. I had Lee dyno them for me half way through 2006, and they were still good as new then.10 laps? Ouch. That would seriously suck. The Honda app's from Koni are pretty friggin' bulletproof. I mean "bulletproof" like they can go several seasons before needing freshening.
