Yes, using bmax rear arms. Didn't try the shorter wheelbase.

Another issue is the track we run at has 2 sections of small "ripples" that upsets the far quite easily, meaning the rear of the car will buck and kick one way or the other..

Yataba yellow front, green rear
37 and 30 wt oils.

If you really want to gain rear grip you can pick up these tranny shims from Mckune Design

Instant rear traction!

Are you using machined or stock pistons?

Machined pistons all around, diamond coated shafts.

Contemplating getting these, do they really give you instant traction, will they help on a medium grip track.

Yes... lots of forward drive. Been using the 2mm shim for a couple of months now with no complaints

Anyone had some success finding a setup to keep the rear end planted just after the apex of a tight turn when getting on power quickly? No matter what I have tried, the only resolve is patience to get squared up first. Those McKune spacers didn't do anything, weights didn't help, tried several camber locations and spacers w/o luck. I've driven other buggies and none seem to have this issue. Med bite turf. Car is fast, but it (I) could be faster if I can find the answer to this.

Do the ymax conversion. Whats going on with you sounds like a lot like my experiences that were solved as soon as I went to the ymax.

What's your setup? We have 2 turf tracks out here ranging from med to high bite

I was just thinking about getting this car then started looking at the pics and saw how the tranny was layed down and wondered if it was designed for carpet. So there aren't any setups that would make this car good in low traction conditions?
I was also looking at the xb2... which has 2 versions one for dirt one for carpet. I like the look of the yokomo and the replacement/upgrade parts aren't as high priced as xray but if it can't be setup for dirt I guess I have no option. I have no carpet tracks around here at all.

I've tried several, derived from the kit base, my own and even some pro's. If you have a proven good setup i'd be willing to give it a shot.

I'm using Lee Martin's warm up setup with a few tweaks. On your local turf track what tires are you running
