The aluminum back suspension system holders are installed with 2 bigger screws in the place of 4 smaller screws for improved reliability. The holders’ lowest place is 1mm lower than previous models to simply help produce more traction when needed. The �23 framework provides extra approval for this reduced place. The trunk wheelbase setting is modified by going top of the and lower arms across the longer suspension system holder pins. CNC-machined from top-notch Swiss 7075 T6 aluminum. Ebony coated.
