Currently in development!

Adds rear lower diffuser and rear bumper valance from Cayman GT4 models.  Fits 2021-2022 Cayman GTS 4.0 and Boxster GTS 4.0 models.  Depending on the application, modifications and additional parts could be required.

Suncoast Note:  This is a functional piece which changes aerodynamics at high speed.  For this reason, we recommend adding front spoilers and rear wing to compensate for the additional downforce and to keep the car balanced at high speeds.  Use and install at your own risk.
