Craig-sez is absolutely right about race tech. I went with their online specs when rebuilding mine, I even spoke to someone there for advice on stacking the shims and I wound up with pretty stiff forks for my liking. They're much better but need. Some work. Also I'm 260 lbs now and the spring I got from them are too stiff, unknown they carry stuff for your weight. Honestly, I have an ohlins rear shock and race tech internals(gold valve rebound and compression and new springs and I feel like I have more adjustment with the forks, racetech does a great job for what it costs!
