Features
Chassis plate
Chassisplate in 3mm 7075 T6 aluminium , with machined pockets to create flex and or make lighter. Kick-up angle on front as need due to the race-rules. Countersunk holes.

The ballraced front anti-roll bar system, consist of a spring steel bend wire, which is guided through the diff-cases and run 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.
Shock tower and body mounts front
4.5mm thick carbon shocktower with 5 upper positioning holes for the shocks and and 6 holes for roll-center positions. 1 centrally located adjustable bodymount , and 2 forward mounted adjustable bodymounts, 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
Ackerman plates
With the design of the steering bell cranks when changing the Ackerman you will not need to adjust your steering tie rods. You simply will only need to adjust your end points on your radio..

Rear 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.
Shock tower rear
