Default GT4RS rear diffuser aero fins

Does anyone know how much this actually helps? I just received the pair for my GT4 and realized they don’t give you screws, so waiting on those so I can install.

Did you get the RS center diffuser as well or only the fins? Can you please update us on the install?

There's a good possibility that the center is different as it contains the holes for the screws to attach to the fins. As well as, notches to slide the fins on.

i guess i’ll find out soon enough. Hoping since Porsche likes to reuse parts across many of their vehicles, crossing my fingers. Or maybe everything will fit but I have to just drill the screws in. If I need a new center, I’ll just return it. Don’t see the value to spend all the money for side fins

based on mounting points maybe it goes into the rear bumper and not the center piece

Not sure why @Shawn Hong is so secretive after starting this thread and wanting answers.

NP. I don't think Shawn Hong was being secretive or anything like that.
