What do you think about put the body more forward or back respect the chassis?

I think with the body more forward and chassis more back (more space between body and bumper) is better for asphalt.
And the opposite (less space between body and bumper) is better for carpet.

Another cuestion about the weight. If I put 20, 30 or 40 gr. in the front of the chassis... What is the reaction of the car? More steering? ...

Thank you friends. Regards.

The general rule is that the further forward the body, the more steering you get, further back gives more rear grip, same goes for the wing.

Aaaaa thank you Skiddins.

Then for get more steering put the body more forward, I think this is best for asphalt.
And the body less forward rear grip for carpet.

And about the weight??

I believe putting more weight at the front smooths the steering and might give a bit more on power.

But normally you want to addd weight to the centre of the chassis

Ok thank you very much Skiddins. I will need a body for asphat and another for carpet
