no, that's wrong. In the apex of a turn the more weight on your leading tires the less traction you will be able to manage. You need dynamic weight on the wheels, but too much static weight to start with and you understeer or "plow like a pig" as a metro does from the factory.

the opposite -- too much weight in the back -- results in oversteer, which is unpleasant as well.

Corner weight on a race car should be 50.05% at most, and ideally 55% or less front to back difference. That front to back is a lot harder to manage when working within strict rulesets, like a spec or showroom stock series.

I do see your point, however, with a FF car, there may be some benefit to leaving a turn with a little extra weight out front, but the snow plow effect diving into a turn may negate that.

Granted a balanced vehicle is a must, lightening the car, regardless of the drive train, will allow you to move with less rolling resistance and with more powerful acceleration and higher top speed (within the mechanical limitations of the car). There really is no substitute for lightening a vehicle.

absolutely, we are completely off topic at this point and you're right.
