It appears that you have received some sound information from fellow members here. I also see that you visited a dealership. Have you considered maybe getting a second opinion? If you do, I can assist you in locating an certified dealer near you to offer a second opinion and other options. Let me know, here to help.

Mine would run great unless it spent more than a few seconds near redline then pedal went soft.
One time I was going down the highway and just pressed the clutch in and revved near a friend just to make noise and it did it. Didn't even shift anything.
Have new clutch and PP to install, not in a hurry since it drives normal otherwise, but when I throw it in I'll inform others.
I think the PP problem is WAY more common than people think.
Try that. Going down the highway just press in the clutch and let it hang out near redline for like 3 or 5 seconds, if your pedal gets soft I bet it's the PP. Search here for more info about this.

Just recently I did a test where I floored it up an onramp onto the freeway. I tried to shift at redline and all the gears were really notchy and by the time I tried to switch into 4th gear I was locked out of gear and the clutch pedal was limp and almost all the way to the floor. I pumped the pedal like crazy and brought it back to life. I got off the free way and went back around. This time I decided to try and shift at 5k rpms instead of 6300pms. I pinned the throttle again and banged through every gear at 5k rpms. It shifted flawlessly, went into gear every shift as smooth as butter and the pedal never went limp.
I can't believe I bought a new master, a new slave, did the drill mod, and wrapped my clutch line in heat resistant tubing when all I needed was a new clutch kit so I could get rid of my stock pressure plate. Years ago when someone started a thread about having a hard time shifting at high rpms and everyone was telling them they needed to get a new slave or master, I remember this one guy coming in and saying it was the pressure plate plate fingers getting sucked in at high rpms, and everyone just ignored him. Now I see that he and some others that have said the same thing were right on.
I just ordered a Monster Level 1 clutch kit, and when I install it if it instantly fixes my shifting problems, I'm going to ask to rewrite some of the manual transmission sticky to include information about the pressure plate issue.

Happening while "spirited driving" is usually explained by saying "water boiling in hot fluid", the FAQ should say that if it happens during spirited driving try testing it with revving and NOT heating up the clutch (like sitting still or disengaging clutch on highway), and if it happens then it's likely the PP.
Anway I'd try it clutch IN and see if the pedal gets soft, then clutch OUT and see if the pedal gets soft. Either way make sure the car and clutch are cold to counter the boiling water in the fluid arguments I seem to always get.
Please reply with your results.
I would also check your pressure plate bolts...my clutch in my GTO had similar issues and I found they had loosened up...Always check torque and add dab of blue locktite now.
I replaced master, slave, clutch line before i found it was just loose pressure plate bolts....
Oh and check your Pressure plate I had another issue where I had a crack in mine on one of the tabs which also made it shift like crap at high rpm

The replacement? ACT single disk with street/strip disk 745 tq rating SFI rated. Have this same clutch in my GTO and Z06
