Hum, I put new parts on my 501x getting it ready for next months race.
However I'm uncertain if Hupo's 511 setup will work on my car.

Jimmy do you happen to have his old 501 setup? I need a setup for high traction clay.
I tried 35 wt in the front and 25 wt in the rear and that worked ok. But I'm thinking 35wt all 4 corners would be even better.
I have been using associated shock oil the clear kind.
