Front:
AVID Yellow (3.23lb similar to AE Green)
AVID 1.5+1.1 pistons
Losi 32.5 oil
-1 camber and 0 toe, inside on the camber with .060" washers and .060" for bump steer.
Rear:
AVID White (1.96lb similar to AE Green)
AVID 1.6+1.1 pistons
Losi 32.5 oil
-3 camber and 3.5 toe block. NO ANTI-SQUAT SHIMS. Shaved brace with 2mm shims and silver (taller) ball stud). A hubs.
Changes I made for this week that I could really feel were the anti-squat (this the caps) and running a shorty rather than a full pack with the ESC in the tray. Also do NOT run traction compound...Simple Green if anything. I find ProLine Tazers to work well in this track condition.
I had been running 2 deg anti-squat, full sized packs and traditional ESC on the left in the past and with the changes found the car to be WAY less loose coming out of corners and it would hook up much better when I got on the throttle.
Edit: I don't claim to be a great driver and I didn't win any of the races this week (it was a 4 race poker run) but I did get progressively better as the day went along and I got back into driving (hadn't run in a few weeks) and adjusted to a new track layout. Wound up 3rd in the final race if that matters.
2nd Edit: Another guy at the track made a couple of other suggestions that make a lot of sense but I couldn't change at the track. Stock plastic servo saver was one that made some sense. With the track being bumpy the car will react a bit slower but will track straighter (his claim). No carbon arms in the front...again run the stock stuff to absorb the extra bumps and ruts.
