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 3 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
