How to resolve a twitchy back-end in 1/8 buggy?

[jhautz]

If the back end is sliding out to easy in turns you can do a few things to try and settle it down. First is to run softer springs/lighter shock oil in the back. This will allow the back end to roll a ltiile more and outside wheel to grab harder. Lighter or no sway bar in the rear could also help. If you are already feeling like the suspension is soft, then stiffening the front end will have a similar effect as softening the rear end. A stiffer front end will "push" a bit more and prevent the rear end from sliding as much also. Another possible solution is to raise the roll center on the rear end so the chassis rolls a bit more in the back and the rear end grabs.
Here is a great manual on chassis setup. It is from xray, but the principles apply to all buggies and truggies. Check it out.

Thanks Jeff - that's a great PDF. I gave it a quick read through and I think I am going to try to raise the rear roll center a little bit and that adjustment most accurately describes the problem that I am having.
