My 05 Magnum has the battery located under the trunk floor by the compact spare....designed that way from the factory to improve the F/R weight bias. The Magnum has a "traditional" drivetrain layout, longitudinally mounted V8, auto transmission and RWD, so weight and balance is good. Moving the battery to the trunk makes it even better.
FWD cars like the GP are hopelessly unbalanced with all of the weight above the front wheels, would moving the battery to the trunk have any measurable effect? Anybody tried it?
