Exotek Racing have released this ultra narrow LiPo chassis for the Serpent S411. This extra soft chassis is aggressively shaped for extra flex over the stock S411 chassis and uses US made bi-directional layup carbon fiber for maximum flex traits. The rear section has added cut outs for greater flex at the motor mount for increased rear end stability allowing you to drive into corners harder and power out faster. Great chassis to have to extend tire wear and generate maximum grip for controlled tire races. Also new is a steering crank brace for the S411 which stabilizes the steering cranks without stiffening the top plate to maintain natural grip and consistent steering.
