If you 're serious about the handling of your Boxster or Cayman, or wish to take you Porsche to the track, you 'll want a technobrace. This simple yet effective piece ties the lower rear struts together, which move considerably under heavy loads. when the struts move, it changes the rear camber at the least opportune time, when cornering hard. After installing the technobrace, the lower struts stay put and the rear stays planted. The technobrace does not effect daily driving, and installs in minutes with common tools (access to a vehicle lift is recommended) and comes with hardware and instructions. For manual transmission cars only.
