The ZX5-FS2(sp) doesn't do anything odd at all, all the adjustments do exactly what you would expect. My only warning is that the car is very responsive to setup changes so small steps can make big differences on the track ... take it easy.
The car generates a lot of both rear traction and steering so nothing radical needed, just throw it down and enjoy it
If there is anything specific then shout and we'll do our best to explain.
