A friend of mine who owns a race shop that does alot of Porsche work said when queried about reducing travel on the 914 brake system that the 23mm master cylinder from a 930 would far better reduce the travel over a 19mm master cylinder.
Has anyone done this mod and if so, what were the performance gains/differences?
Thanks

I'm assuming your brake system is nowhere near stock?

I'd not go bigger then 19mm for a stock or near stock braking system.

That would be correct sir, and I also run a sbc so "mo better" braking is always sought after.
