I've been running a Wilwood clutch master for a while now--GS Compact Integral Master Cylinder, PN 260-15098. Still using the same long-throw slave I've had in the car since 2009 (Amazing that it's lasted this long). The Wilwood clutch master works just fine, but after a couple of failures (fewer than the many "OEM" masters I went through), I may go to a Tilton clutch master for basically the same reason this guy determined when comparing the two... https://youtu.be/Hz4AlAt7DJ8
