The Top Racing 1.6 ceramic balls at amain are kickass for the thrust. Or of course bfast is always good too.

I probably shouldn't ask this: are your front inner ball studs on the outside hole? I have them in the middle. Caster inserts per manual (0 deg). And I did not get the left and right mixed up

When you say it's dead middle on the hudy, I believe you, as it was with my rb5. Set up per manual, never had to touch them until the ball cups wore out. I don't run front toe-out. If all else fails I'll go with what's worked for me: whatever works. Thanks,
i'm in the farthest hole out on front bulkhead thats what the suplemental sheet called for

Orange is fasflorescent orange right out of the faskolor bottle. The blue is a custom mix that I have been doing for a while now. Custom mixed colors is where you get all the good colors . Its actually two blues.. a darker blue around the pinstripes, and a lighter blue in the middle.

Im having a tough time getting the car to rotate on power and even off power. I feel like I have to pitch it on the 180s to get any type of speed. On power exit I just go straight.

Im using Jason's setup with AKA Vektor fronts in Red and Rebars in Red.

Does that tire combo work on your RB5 down there?

I made some more adjustments tonight and went even faster!

Started the night with the setup I posted:
http://mobile.liverc.com/results/?d=...K_BUGGY_NT.xml

Then for round 2 I made some adjustments to get the rear end to be a little more locked in after a 180 coming on power. I lowered the rear shock mount to the furthest inside hole. This helped and I went faster.
http://mobile.liverc.com/results/?d=...K_BUGGY_NT.xml

Then for the main I felt it was a little to stiff with the shocks down so I went to a softer spring in the rear, switched to gold rear springs, car was amazing for the mains. I was clicking off 19 second laps like it was nothing.
http://mobile.liverc.com/results/?d=...T_(A_Main).xml

Was on a 19 lap pace (which obliterates anytime a stock buggy has gone on that layout, only the good mod drivers or 4wds go 19 laps) but Kevin Smith and I started waiting for each other so we could race.

I'll make a new setup sheet for what I changed tonight and post it up.
