I think the idea of the aluminium bottom plate is to add weight low in the chassis, other wise carbon fibre is the better choice. Heavier cars are more stable and generate more traction, especially for high powered modified motors and the fact that battery technology is getting lighter.
Stock racing on the other hand, i.e. 17.5t as we do in Aus, being light can help acceleration with tall gearing. The 503 and the 201 are clearly designed for high powered motors considering the drive ratios that come standard.
Some one buy my FF01's so I can afford one of these beauties!
