The stock 17mm master cylinders are NLA. 19mm MCs are running about $235. Automotion has a 23mm MC that's only $110. It says it's for 914s with upgraded calipers, but I'm wondering about using it with stock brakes. Anyone have any experience with these? There is no clue about whether it is ATE so I suspect not and so I also wonder about longevity.

I have a 23mm master cylinder with Boxster calipers. I had the 944 turbo calipers with it, and it made for some really hard pedal pressures. It also made it really hard to modulate the brakes on the track. When I went with the Boxster calipers, I almost went back to a 19mm master cylinder, but I decided to wait. I like the brake feel with the 23mm master cylinder and the Boxster calipers. It is easy to modulate, and it stops extremely well.


With the 944 turbo calipers, Betty described my brakes as "70s Chrysler over boosted power brakes". I hesitate to think what it would be like with stock calipers.........

But definitely not a good idea.
