a kart chassis is completely different from a car in terms of setup, solid rear axel, chassis is the suspension, some only have rear braking, etc.
and, if you ever want to get into a discussion about how to solve understeer with a kart, you'll get 100 different responses, all swearing they are right.
probably the same with the car. i have understeer w/ my 04 sti. one camp says rear sway bar, another says front.
i tend to believe in work on the area with the problem. not enough front grip? adjust the front. but, i am talking about karts, so, i guess my answer is useless to this thread since they are completely different setups in terms of geometry, etc, from cars.
