This past weekend I finally installed my Philistine clutch master cylinder. The kit was well made and of high quality. It took a full day of work to get all the items out of the way that would help facilitate the install and get everything buttoned back up. Of course that was with the "required by law" beer and smoke breaks. My GF helped when needed but otherwise it was a one-man job and fairly easy to perform. You just need a lot of patience and small hands or at least be a contortionist. I highly recommend you remove the wiper arms, the wind trays underneath them and the wiper transmission. Opens up things so much more. The stock master is a bear to remove without removing the brake vacuum booster. However, I found you could press on the tab that locks it in place and rotate it counter clockwise and it will move out of the way enough to facilitate the master coming out. Then just put the booster back in place and rotate until the tab locks again. I flushed all of the old fluid out of the lines, etc that were remaining and bled the complete systems with my mityvac. Worked like a charm. Made the required adjustments to the clutch pedal rod and went for a drive. Clutch pedal feel is much firmer and actually feels like a clutch pedal should in my opinion. Shifts much better and no longer pops out of 6th gear like it used to on the highway. I've got about 3 days on it now and zero issues. Very happy with it. Made a big difference.

The Philistine clutch master was a setup created by a member on this forum and ls1tech to use a Tilton or Wilwood master cylinder. Some folks thought it was the greatest thing since sliced bread. I had it, had nothing but trouble with it, and went back to stock after spending lots and lots of time fighting with the PMC.

I had nothing but trouble with my setup also. I ran it with 2 different clutches, plus a tilton slave bearing also. It's not worth the effort in my opinion.

It's also referred to as the willwood master of more recent posts. Mine was pretty nice at first, but quickly degraded and required constant flushing.

OEM hydraulics with a -4 an feels way better and has a better clutch pedal feel. Especially in traffic.

Question. Had my 2005 V since November. 65,000 miles. LOVE IT! That said, if I sit in stop and go traffic, clutch in and out a BUNCH I get get a slight "hitch" in the pedal feel. It goes away when I don't use the pendal as much. Traffic gets moving or I stop for a bit.

Thoughts? Since you guys sound like you've scienced this out a bit was hoping you might have a suggestion.

When. Is the last time you bled the hydraulics? I do mine about every 6 months, need it or not. Use quality fluid, Motul RBF 600 makes a nice pedal feel, ATE is also great, I use the stuff speced for 2010+ German car ABS systems and it also produces a wonderful pedal feel.
