Todd: I messed around with that underdrive setup at Fernando's a few weeks back. I found it a little stuck in the corners and pushing on the big sweepers. We did sugar water the track in the morning, but it was humid and not many people running. I made a few changes that perhaps may be of interest:
Front Shock: 4
Rear Shock: 3
Front Camber link: 3
It works very good in the wacky dog leg at the end of a sweeper and seems really balanced through-out.
I am going to mess around with the droop and the camber link positions. I was using the 4 hole in the front and 6 hole in the rear with the non-overdrive setup with 50Wt oil in the front.
