WHATS BETTER
 

Whats better,

To have the car on the weight, OR have the car balanced letf to right??????

balanced left to right everytime for sure, if once you've balanced the car left to right you find its over weight you could slim it down with titanium screws all over which should keep the balance and bring your weight down :cool:

Weight makes you slower all the way round the track, unbalanced weight might make you slower on a couple of sections. Answer seems clear to me.
