Default Clutch Master Cylinder Options

Is there a better option for a clutch master cylinder on these cars? Iíve rear that Philistine used to make one using either a Wilwood or Tilton mc but it seems like heís stopped making that piece. Are there other bolt in options?

He still sells his kit. I'd go new OEM myself.

After having Tilton and Wilwood master cylinders fail, I went back to stock. I don't know what it was about my car that the PMC didn't like, but I spent way too much time ******* around with it and can't say I saw any appreciable improvement in clutch performance or feel.

Iím torn. I need to bleed the system to see whatís what because some days it will shift well, but not awesome. Usually if itís cold out it will shift better but then the pedal feels like a sluggish sponge. Iím thinking there must be either air in the lines, the mc is done and canít push the needed fluid or the fluid is done. The car only has 112k kms on it and Iím trying to figure out if the mc is dying or what since there are random times when it wonít let downshift with out rev matching almost like there is a block in front of the shift gate.

At 14 years old low miles donít help that much. Rubber and seals just wear out.

My stock unit has performed just fine, so I don't see any reason to replace it with anything other than stock. I'm at 189k and it could use some new fluid (actually haven't flushed it in 90k), but otherwise I have no reason to suspect it's bad. At 112k it could be a number of things if it's all original.

If I switch it out Iíll probably stay stock as that seems to be the common choice. One thing that makes me think itís the MC is that if Iím coasting in first gear with the clutch in I can feel something happen in the pedal and then the clutch start to drag where if I try to take it out of gear I canít and I need to let the clutch out, put it back in and then itís good. I canít figure out if thatís the MC or if there is air hiding in the lines. Iím going to do a big flush/bleed this weekend and see if that solves it.

Make sure to get the motive powerbleeder and follow the pmc bleeding instructions. Everything else did not work for me, plus it was pretty easy with that setup

I got a PMC in November (he does still sell them, just PM him) and if I could go back I probably wouldíve gone with something else. Nothing wrong with the PMC, it works exactly as advertised (install was a bitch, but that will be the case for literally any mc on this car) but the stiffness is a bit over the top for a DD if you have a commute with a lot of traffic. I can drive the car fine, but it gets tiring.

Iíll probably switch MC when I go LS7 clutch.

YMMV, again, the PMC works exactly as advertised, no faults there.

I've had both stock and the pmc/willwood.

I went back to stock. Ran an ls7 and my current twin disk just fine and with considerably less pedal effort.

Buy a centric brand master and save the cash for other mods.

Many people however disagree with me on this. Your mileage may vary.

There was absolutely zero gain other than replacing a worn master with a new one in my case.
