It's simple. We used to do it on the Sentra. Five people in the back and a couple of sacks of rice... :lol:

Avid autocrossers and track-day afficionados can get 55-45 by juggling weight around. Fiberglass or carbon-fiber hood, battery relocation, and removal of non-essentials like the airconditioning system. Aftermarket exhausts also change the weight balance of a car, as the catalytic converters and the heavy exhaust manifold usually reside in front.

The Eldorado managed to keep its 60-40 distribution only because there was so much car aft of the engine. Small cars with big engines aren't usually so lucky. The Dodge Neon SRT-4 was 65:35.
