If it isn’t leaking and is losing hydraulic pressure it would have to be the clutch master cylinder. If the slave was losing pressure it almost has to be a leak. I am not convinced it is losing pressure. Clutch master cylinders can go bad but...
Replace the clutch. My 2011 behaved exactly the same after bumping the rev limiter up to 7500. The clutch looked fine. A new clutch and slave cylinder fixed everything.
It's also a matter of the right pressures and suspension. If you are not taking good care of your tire pressures during a track day aka checking in/center/out temperatures and making sure your pressures are not rising to the moon by bleeding them...
Not to sound like your dad but if this is your first time on the 3R or similar be aware that they will have a lot less grip than your old PS4s when cold. You have to get some heat in them. I looped my car on the out lap one time on them at...

I will be using some Goodyear F1 Supercar 3R's Memorial Day weekend for the first time on my 2021 GT500. This is my first time running the car at the track without the Michelin PS4's that came stock on the car. I have been running the PS4's for 5... (see full post)
It's mostly a question of life. If you don't mind bolting them on, Trofeo's are as good as anything. I wouldn't be that concerned with a difference in lap time. OF COURSE the longer wearing tire will be slower. I'm sure there's a tire 3 seconds...
The old standby Goodyear SC 3R is right there with the trofeo, Hoosier TA, R7 etc. in most tests, and I believe the 2026 USAA GY discount is 25 percent off. Plus the 3R is a more affordable tire even before the discount. You can get a whole set...
Some people are easier on tires than others. Some overdrive, some drive off the rear, some tracks murder certain tires (Gateway Roval is my home track). Yokohama are not tolerant of these things.I suspect that the Pirelli might work well for...
This is how my Front A052 looked like after today track day (104 laps on them / 193 track miles and 1933 Street Miles). I did 5 new PBs with them and they still perform reasonably well. I think this tire handle abuse very well.
Funny I also snapped a thrust washer at Inde and it led me to getting the GT350 axles so I get rid of them. Driving the car with the dash a christmas tree is doable but not fun (in my case it heavily ramped up the booster so the brake pedal had...
Are the GT350 axles required to remove the thrust washer? I read that people are just removing it, then torquing the axle nut about 200 ft-lbs with red loctite (over the specified 100 ft-lbs + 45 degree arc) and adding a witness mark to keep an... (see full post)
Can report back now after 2 weekends of using the KPM pump at Chuckwalla and COTA, I have ran the car down to 1/8th of a tank and have not gotten any fuel starve
