Anyone switched out the brake air deflectors on their Cayman/Boxster fior the larger GT3 ones?

There is some confusion here because two different parts are being discussed and they have similar part numbers.

982-505-201-A Brake duct, top half, LH rear
982-505-202-A Brake duct, top half, RH rear
982-505-569-A Brake duct, bottom half, LH rear
982-505-570-A Brake duct, bottom half, RH rear
These are for 718 GT4 rear LCA's. They consist of two halves that clamp onto the LCA and screw together. These DO NOT fit the 718, 718S, 718T, 718GTS. Different LCA's.

What will fit the rear tension links on non-GT4 718 are these:
982-505-569
982-505-570

The tension link will need to be removed and the air scoop slid onto it, then strapped in place. The plastic strap is built in.

Thank you, I completely missed that as yes the part numbers are really similar.

No worries as it is easy to forget things like this. Also do you know if the GT4 rears will actually fit the GTS? I know these were talked about in a previous post but nothing on fitment.

If I am not mistaken, the 718GT4 rear brake ducts consist of four separate parts - an upper and lower half that clamp around the left and right lower control arm. PN's are:

982-505-201-A Brake duct, top half, LH rear
982-505-202-A Brake duct, top half, RH rear
982-505-569-A Brake duct, bottom half, LH rear
982-505-570-A Brake duct, bottom half, RH rear

Really bumping an old thread, but just wanted to thank you for posting the PNs for the top bracket—they don't appear on any of the rear suspension parts diagrams, so tracking them down was nigh impossible.

For others looking, the rear right bottom piece has been superseded by 982-505-570-B

Additionally, the screws needed to bolt up the top and bottom parts is PAF-909-059-A

Excellent.

And for what it's worth to anyone contemplating changes, I just had the Porsche Motorsports rear axle air ducts installed on the GT4. (Part numbers for the GT4 & GT4RS: Right: 9F2.071.744.B, Left: 9F2,071.745.B)

In addition and in reference to the very helpful post by @Ix_ regarding the 2-piece brake ducts, installing the Porsche Mtrsprts rear axle ducts required the removal of the top half of each of the 2-piece brake ducts. The top halves do nothing but secure the vents to the control arm, so removing them was not an issue. They are now secured using special zip-tie-like connectors and are better secured than they were with the factory brackets.

I took inspiration from the other thread where Tim showed his lower ducts fastened to the control arm with Zip ties and did the same thing. I had to trim them slightly to fit the GTS rear due to the previously mentioned, these are not the same as the GT4 arms. The top of the clam shell wont fit due to the ride height sensor so I did not install those, not sure I love the snap clips anyway.
