GT4RS rear diffuser aero fins
#121
Saw these tonight...like the OEMs better though but if someone likes CF they have a lot of parts in that: https://friedrich-pm.com/produkt/car...satz-2-stueck/

My fins arrived today and I plan to install them tomorrow. I am not planning to remove the diffuser to install them since I am not going to drill the holes for bolts; however, does anyone know if I have to separate the diffuser halves in order to attach the fins with the tabs/hooks? Or can I slide them into place without having to do anything to the diffuser?

Easy-peasy...I should have waited until I tried them before asking questions. I did not drill any holes but I used a few tabs of 3M tape where the fins touch the diffuser...great look for little money:

Looks fantastic and completes the look of the car. Especially when you compare to the front end of the car that does wrap around to the sides a bit. Now, the rear end does too. Not sure it makes much of a real aerodynamic difference, but I don't think this is really the point for this mod.

Not at the speed that we are at on the streets, but suppose to help with more vacuum of the underside at track speed (>125 mph) per Porsche's GT4RS website . That, along with the front underbody air deflectors completes the package per their description of underside vacuum.
