Aligned with chassis kikc-up for precise landings and to protect front suspension holder and anti-roll bar.
Composite stiffner front and rear, to give extra stiffness, but still allow some flex as needed.
Central radio / servo mount
Composite compact radiobox which offers good space for the steering servo and the receiver.
Battery-cases / side-guards
The main eyecatchers are the extremely low laydown longtudinal placed battery-packs at each side of the car, being part of the side-guards, securely fastened with a fliptop-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.
The motor is placed in the most optimal position in the car, keeping motor-forces and transmission parts / alignment in mind. Only one-screw is needed to secure the BL motor, in the nicely designed durable machined aluminium motormount. Space for additional motor-cooling available as needed.
The space for the motor allows a maximum motor-length of 70mm, which covers most widely used motors ( except for the truggy / monstertruck motors).
Composite steeringblocks combined with 10 dgr C-hubs for precise steering. Spring steel wheel-axles with large size bearings and larger inner with precision threaded aluminum wheel-hubs with offset . Flanged and serrated wheel nuts to guarantee that you will not loose a wheel nut in a race.

Front anti-roll bar
The ballraced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the diff-cases and runs in ballraced steel adaptors. The wire is linked to the lower suspension arm, with a captured adjustable threaded pivotball, for very precise and low friction operation and easy tuning.
Shocktower and bodymounts front
4.0mm thick aluminium anodised shocktower with 2 upper positioning holes for the shocks and and 3 holes for roll-center positions. 1 centrally located adjustable bodymount , and 2 forward mounted adjustable bodymounts.
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
With the design of the steering bell cranks when changing the Ackermann you will not need to adjust your steering tie rods. You simply will only need to adjust your end points on your radio..
Rear suspension arms
Durable longer oversized lower suspension arms in strong composite nylon. On the lower side the special downstops screws are mounted. The lower shock-mounting pins are secured with a small grubscrew from the bottom.
Optional are the composite mud guards, which can mount to the lower suspension arms, and will keep dirt away from your anti-roll bars transmission and wheels.
