Good morning everyone. I was wondering if anyone knew exactly what is or if there is any difference between 718 GT4 CS wing and 718 GT4RS CS wing. The part numbers seems to be different by one digit: 9F2827677A vs 9F2827677B, but the riser and wing end plates are the same.

On the official launch of the 4rs CS, Porsche mentioned that the gurney flap is different(more extended for 4rs cs) and it is shown on the parts catalogue as well as the wing adaptor with more AOA flexibility. However, I couldn't find anywhere if the main wing body itself is different between regular cs and 4rs cs. If anyone has any insight on this, please let me know! I currently have gt4 cs wing and if the wing body are the same I am going to try to acquire the 4rs cs gurney and adaptor and use it on the gt4 cs wing.

Thanks for your time!

normally the last number/letter is just a revision number

Do you happen to know if there are any physical differences between those two or just different serial number for new car?

I was able to confirm with the Porsche Motorsport that the main wing body is the same. Thank you! The thread can be closed.

The Gurney flap is smooth on the bottom vs have a few small step for the CS
