IMO - I have found that driving, using the red and white peppermint bumpers works most effectively for making turns. Be carefull though, a little goes a long way. Setup for it are as follows:
*slam it
*increase spring
*shocks to 2
*rebound to 8
*lower stablizers to 1 or two for both front and back.
*brakes 9
*set the gearing according to the Rome track and your driving ability.
*Computer aided anit-slip, 5 and 10 (defualt settings)
*Max out the HP - I believe only one engine upgrade is available.
This is a squerrly beast, so be careful of the engine weight in the back causing the arse end to flip around.
