How to improve brake feel, Modified 914/6 (conversion) Options

[tornik550]

I have seen a lot of posts regarding brake feel however my setup is a bit different than the articles I have seen. My car is mainly used for spirited street driving and occasional auto-x. Here is my current setup (all components are close to new):
-“wide-A” 911 front calipers
-vented front and rear rotors
-“vintage brakes” 914/6GT rear calipers
-19mm master cylinder
-ss brake lines
-adjustable proportioning valve

I realize my brakes are overkill for my needs. I have bled the brakes many times.

My main question is- would a different master cylinder be of benefit? If so- larger or smaller?

1) 19mm master cylinder is right, as already stated.

2) Your description would tell me air is in the system somewhere. I used to pressure bleed my brakes on my formula cars, about 5 psi to the reservoir is plenty. And I continued that practice on PCars. Drill a hole through an old reservoir cap and epoxy in an air fitting.

3) Dump that proportional valve and use the original, as already stated.

4) Brake "feel" is always a personal thing. On the track, I absolutely hated super hard pads that had no feel (felt like pressing on wood) even though everyone else used them (like Porterfield). I always exclusively used the old Hawk Blue.

5) I would maintain that there's not a good compromise between a street pad and an autocross pad. Much different heat dissipation requirements. Personally, I'd use a street pad (lower heat range) and see how it works at the autocross. Replacing pads more often would be par for the course... but what? Every couple years? So what!
