An enthusiast upgrade. Modifications required to fit these. Not for cars with a sunroof.
We've been getting questions about these, so we did some research. On 992 GT3 RS models, these roof mounted fins direct hot air from the front middle radiator outwards, and away from the rear engine decklid. With some modifications and double-sided adhesive (not included), this can be added to 2013 or newer GT3 and 2015-2019 GT3 RS/GT2 RS models for a more aggressive look.
Consult a professional for installation. At a quick glance, some tabs must be removed, the surface must be cleaned properly, and double-sided adhesive would be necessary to fit them. Install and modify at your own risk.
