The Awesomatix A800 Aluminum Chassis has been designed for high bite conditions which we are now finding on the new CRC black carpet. We have widened the inner pivots 0.5mm on each side (front and rear) which stabilizes the car allowing you to drive it harder with more confidence. We have also brought back the optional battery position by allowing you to move the battery back 6mm to increase the cars rotation. We recommend using this chassis to increase performance on high to medium bite conditions.
