The general consensus is: skip the 23mm+ brake master. Noted. I have seen a number of passing references to a VW brake master (22mm) that is said to bolt in without issue. Based on my research, the VW part number is: ATE 357611019. For those in the know, is this number correct? I have also read that a 22mm from Mercedes will work--I'm open to this option as well.

Any feedback on the intended upgrade would be appreciated, though I am aware of the increased pedal effort and am not concerned . . . unless those in the know say I should be.

TIA.
357 611 019 - this is for the 20.64mm master cylinder

357 611 019 B - this is for the 22.22mm master cylinder

911 355 322 00 - straight reservoir feed fitting

911 355 323 00 - angled reservoir feed fitting

7mm blue braided brake reservoir hose

updated version 911.355.012.02

W 911 A/M calipers the pedal ratios are

20.64 mm 35.192
22.2 mm 30.42

lower pedal ratio is better toa point w/ better feel and control
