It's actually 3 pieces 27and the two 22 parts and yes, many have About a 5-10 minute job.

I know its 22 as well, I hadn't seen if anyone had fitted the centre ones (and whether the fixings were already there/had any benefit for us) and someone was also asking for those part numbers which again, hadn't seen anyone else post up.

Everything is there and all the pieces come together as a kit. I can't really say if it helps or not.

22 and 27 are separate parts

22 included 2 parts per side

27 is just the additional centre vane.

You’ll have to cut the underfloor and add the attachment fixings. Not sure if there is a template for the proper placement

27 is not in the 718 MR kit (and I probably won’t bother to add them tbh), But is a standard part for 991.2 GT3 & 2/3RS and 718 RS… if you don’t have FAL these parts may well take hammering in particular IMV, but should further aid cleaning up that underbody air flow allowing the rear diffuser to be more efficient and effective.

I would have sworn mine came with both and they bolted right up. I'm going to have to get under my car and look.

9GT-807-913 Gives you 2 parts per side that attach to the wheel arch liner for tyre wake and the ‘bat wings’ That’s 22

27 is 9GT-807-913 A that gives you the further inner blades.

I have heard/ read that some of the MY22 cars come with pre-cuts in the underbody/floor trays though!

So finally got home and looked under my car, and I do not have part #27. Would have sworn I did. It's only $90 so I ordered them and will see what it takes to install them. Sorry for any misinformation.

Interested to see this when you get them/installed. Update us here if you can when you get it sorted.

We've all been victim to the several-hour, "45 minute" projects a time or two hehe! Great picture! that shows a lot. Thanks! What year is your car? Interested to see if there were already pre-drilled provisions for these? Mine is a '22 GT4 that I would be installing them on.

seems that these can be positioned fairly easily based on the outbound vanes. But preinstalled mounting points would be handy.

hey folks, anyone can look up or have replaced the highlighted underbody aero bits on our cars in this image? Mine is a bit beaten up from sending it too hard on track. Thanks in advance!

I don't know. Haven't had a chance to get under there and look. That picture is from a friend of mines GT4RS. I'll probably get a chance this weekend. Got some work I need to do on the car, so I was planning on putting it up on the lift.
