Brake ducts from Audi RS3 8Y

[TheSwede]

I have the RS3 8v brake ducts on my Leon Cupra R 2018. Have anyone tried the new ones for 8Y (2020 and onwards) on a Leon cupra MK3 or a Golf mk 7 with better capacity? Do they fit?

New part number 8V0407812A, 8V0407811A.

The old numbers for RS3 8V are 8V0407812 and 8V0407811, just an A missing in the end . I have used them on my Cupra and a Golf R mk7. Fitted okay. FYI I have 370 mm discs and Brembo 4 pot calipers but I don't think this will have any impact of the fitting.

Do these make much difference?

No not fitted the new ones, I am still using the old ducts and this on 380mm Revo big brake with Super Pro ALOY0018K Control Arm and again no issues with fitting or in usage.

@H Rafiq from way back when I had only one side fitted I certainly got a different heat reading on the disks between the side with one fitted and one not but I have these fitted for track use not sure how much benefit you get from occasional spirited road driving.
