The ball raced front anti-roll bar is a wire type, with very easy and fast open access on the front, captured in the aluminum front braces. The standard wire is 2.5mm and 2 other as options. The pivot balls link system directs the power to the bar in a smooth way and easy to adjust the tweak with the captured pivot ball. The ball raced rear anti-roll bar mount in steel adaptors, which run in nylon spacers in the aluminum holders as integral part of the rear brackets, with 2.5mm as standard wire and 2 other as options. The anti-roll bar links to the rear lower arms with adjustable track rod guidance.
Front one-way axle
In the front the black anodized aluminum front axle with Japan-made one-way bearings features a free of play and super-true pulley assembly. Spring steel drive cups, strong, long and thin spring-steel driveshaft with CVD system, and ball raced spring steel wheel axles with aluminum quick-change levers. The open front end design allows for very fast and easy removal of the front axle or parts.
The rear end construction with the aluminum brackets holds the rear axle. Its open design allows for ease of maintenance and cleaning, and needs very few screws to dis-assemble. Replacing a belt in case needed is simple and very fast too. The eccenter on the rear shaft allows for belt tensioning. The suspension bracket and rear plate hold the pins firmly and have composite roll-center inserts to allow for fast and precise changes.
The solid rear axle with new lightweight 48T pulley in Serpent spring steel, 9mm wide with 4 slots for the pin.
In the rear strong spring steel drive shafts, spring steel wheel-axles with aluminum quick-change levers and a spring steel rear axle. Very durable and lasting drivetrain.
The long durable rear lower wishbones can be used left and right. The lower rear arm holds the low mounted link for the rear anti-roll bar and holds the aluminum mounting plate of the rear shocks, which allows a position which is very far to the rear and to the outside for best performance/ geometry. The lower arms also hold the easily accessible down-stop screws. Nylon clips are used on the lower rear pins to change wheelbase.
The durable composite uprights hold the ball raced spring steel wheel axles, with aluminum quick-change levers. The 8.5mm pivotballs are used to adjust camber fast and easy with the smooth hex-shaped plugs. The arms of the floating body mount to the top of the uprights. On top of the up-right spacers can be added under the pivot ball to change roll center and camber change. Optional carbon fiber disks can be mounted on the side of the uprights for aerodynamic reasons.
Front suspension arms
The long durable front lower wishbones are mounted super low in the car, and feature a semi covered “leg” for the inner suspension pin and the pivot link for the front anti-roll bar system, it also has an extension for the down-stop screw. The lower arms hold the lower aluminum shock mount plate, which allows a further out and higher mounting point for the front shocks. The strong upper arms can be used left and right. The front lower arms connect to the aluminum front bracket on very low nylon holders. The kit includes 2 versions, low and super low. This system also enables you to replace a front driveshaft very quick and easy.
5mm stiff aluminum chassis in perfect symmetrical shape for even flex and weight distribution.
Countersunk holes, chamfered edges for more cornering, ground clearance. All screws from the bottom are with 2.5mm Allen size. Many pockets in the chassis to make it very light but still stiff. As optional the full carbon chassis can be used which weighs around 90 grams less.
2.5mm carbon fiber top-deck to create a strong and stiff connection between the fronts and rear-end of the car. The servo is mounted in the center of the car and can hold large and low profile servos. The center offers also space for the receiver which can be glued to the small plate/ clips.
