After some advice,
I've got a Rascal on standard suspension setup, only thing i've changed is the tyres which are now Proline Dirt Hawgs. Happy with them, only problem is that the car is now really unstable, and rolls far too easily. With the older tyres, the grip would give out, and the car would spin, but now its a problem with them being too grippy.
How best would be the suspension set up? Should I be looking at harder, softer, thicker or thinner oil, or more or less pre-load on them?
I was considering changing the rear springs for harder ones, as the chassis bottoms out quite a lot, would this help?
Any other advice would be appreciated, thanks!!3
