Product Description

The RSS Tarmac Series Performance Transmission Mounts are designed for the Porsche driver who demands the absolute maximum in precision handling, feedback and control from their chassis. 

With factory Transmission mounts, the drivetrain will move independent of the chassis during acceleration, deceleration and cornering loads. This movement can upset the balance of the vehicle and create negative handling effects.

Our Performance Transmission mounts minimize these effects by utilizing specialized polyurethane bushings which offer a firmer, more direct driving feel with optimum feedback.


  • This upgrade will NOT significantly affect ride quality or cause knock sensor issues commonly associated with solid transmission mounts.
  • AVAILABLE FOR ALL 986, 987, and Cayman, FITS MODEL VARIANTS INCLUDING Mk.1 & Mk.2 with 6 Speed Manual or PDK Transmission. (DOES NOT FIT vehicles with Automatic “Tiptronic” Transmission)
