Chassis stiffeners

Composite stiffener front and rear, to give extra stiffness, but still allow some flex as needed.

The main eye catchers are the extremely low laydown longitudinal placed battery-packs at each side of the car, being part of the side-guards, securely fastened with a flip-lid, for easy and fast battery changes. The weight low in the car and in the right position, well balanced. The Lipo holders comply with ROAR legal packs / dimensions.

Shock tower and body mounts front

4.5mm thick carbon shock tower with 5 upper positioning holes for the shocks and 6 holes for roll-center positions. 1 centrally located adjustable body mount , and 2 forward mounted adjustable body mounts, all with flip-tops.

Angled steering system / servo saver

The bell cranks are angled to reduce the angle of difference between the total caster and steering plane. Therefore you will have less bump steer and a truer steering Ackerman through the entire range of suspension
