The aluminum rear suspension system holders are installed with 2 bigger screws rather than 4 smaller screws for improved reliability. The holders’ cheapest place is 1mm less than previous models to help create more traction when required. The �23 framework provides extra approval because of this reduced place. The trunk wheelbase environment is adjusted by moving the upper and reduced arms over the longer suspension holder pins. CNC-machined from top-notch Swiss 7075 T6 aluminum. Black coated.
