The buggy was sliding way too easily and it wasn't my driving because I had one of the employees drive it and he had the same issue. He tq's and wins the stock class almost every week so it's definitely not his driving either. The slipper seems ok, not too tight, not too loose and I turned the punch down but not much change. I'm also running m4 suburbs, the most common tire at my track. I had the same guy take a closer look at it and he said the rear end is sitting way too high; the rear arms actually a tad above level. He suggested using a larger anti-squat shim for 3.5 degrees to get the rear end down. Can I just stack the anti-squat shims? He also suggested adding some rear toe. Without buying new hubs, can I just use one of the different arm mounts to add some toe in?
I'm running the standard setup with the exception of -2 degrees camber front and rear (suggestion from another driver). The buggy seemed to push quite a bit in the turns as well, that is when it wasn't spinning out lol.
I really want to get this thing dialed which I know takes time but I want to at least start heading in the right direction so I'm really looking for some more input on setup. The track is smooth, wet, slippery, indoor clay.
Since everything else seems to be accounted for, My guess would be the diff or slipper is not adjusted properly. If the diff is too tight it can create a posi-traction effect. So when you try to accelerate out of a corner both wheels are spinning at the same speed causing a loss of traction and thus a spin out. Happened to me in the past. Having one of the fast guys set my diff properly did wonders for traction.
