The aluminum back suspension holders are mounted with 2 larger screws instead of 4 smaller screws for improved reliability. The holders lowest place is 1mm lower than past models to greatly help create more traction whenever required. The �23 framework provides additional approval with this reduced place. A corner wheelbase environment is modified by moving the upper and lower hands along the extended suspension holder pins. CNC-machined from high-quality Swiss 7075 T6 aluminum. Black coated.
