We need an installation procedure for sure since it seems many of us are interested in doing this - thanks in advance to those who can come up with it!

I ordered mine last night, for what I think is a good price from my go-to parts place, Delaware Porsche:

982-807-918-OK1 Z Trim $128.16
982-807-917-OK1 Z Trim $128.16
Estimated Shipping to 32137 via Economy Shipping: $8.90
Total: $264.33

Plastic looks different in texture and color to the existing diffuser?

I like this. Will be doing it for sure. Love the completed look it gives the rear bumper alongside the diffuser.

Hello Bob, thank you so much for sharing the part numbers! Do you know if this order comes with the appropriate screws as well?

The screw part# is 999-919-246-01? And if so we need to order 6 (3 each side)?

By the way, I found the part#s for the front spoiler ends (left & right), which is shown as part 6:

well done! now the question is will it fit with the existing lip, or do you need to order the RS lip. and if so, I wonder is if theres more needed? like the grill.

I bet it is a direct replacement since the rest of the front spoiler looks the same as found on the Spyder and GT4; however, we will not know until someone tries it!

I believe you will also need the main front spoiler part (#4) as well. It appears to be deeper than the regular GT4's on video, but that would have to be checked via parts numbers.

I’m quite sure the part numbers would be different because there should be ‘RS’ logo on the lip

Like Lovetoturn mentioned, from the pictures and videos i've seen it does look to stick out further than the normal GT4 one...... would love to know for sure.

As I said, I think what it is going to take is someone buying the spoiler end pieces and trying them out, and if they do not work sending them back. I would do it but I am still on the fence as to whether I want them...kinda like the way the OEMs look on my Yellow Spyder.

I am doing the rear fins for sure though but again, does anyone know how many screws are needed? I can add them to my order since I have time - the fins are coming from Germany.
