Thanks Mark....they aren't a problem on the road course. One quick pump down the straight or between corners and they work great. The autocross is the real problem! 15-20 turns in 45 seconds.
I do have the roller bearing and pulled them to reinspect last night and they feel like new. I have decided to try a 10 psi residual valve. Bret at Air Ride is using one on the rear of velocity with good results. If that doesn't prove to be reliable and make me happy then it's on to a tapered bearing and probably hydraboost.
