SER-401715 Chassis Carbon Light 4-XThe normal chassis is 61 grams and this light one only 46 grams, so it`s a big reduction of weight.

The light chassis can be used for certain racing situations where more flex is needed, indoors as well as outdoors.

The standard kit-chassis version of the car with its strong center stiffener is as stiff as many standard cars with an aluminium chassis.
