In addition to the torsion bars the chassis has adjustable camber and caster making it easy to change the chassis’ dynamics thanks to the incorporated 20-position uni-ball eccentric washers.
We offer the ‘Racing’ version for this model, which is in turn provided with magnesium OTK components, which is unparalleled in the industry.
The standard brake system is the rear self-adjusting BS6 system. However, the optional BS7 manual front brake system is also available. The MERCURY model is also suited for the shifter categories, which comes equipped with the self-adjusting BS5 braking system utilizing Kinematics.
Finalizing the chassis is the newly homologated OTK M4 side boxes, studied and tested in order to reduce the coefficient of aerodynamic resistance. Covering the OTK M4 side boxes is the new sticker collection kit.
