Unhappy Clutch pedal engagement at the floor during high RPM shifts normal?

Hello everyone, i recently purchased a 2012 mustang V6 and the clutch pedal seems to engage very low during spirited driving. The engagement point basically drops to the floor if i shift anywhere above 5k RPM.

I have been driving manual cars since i got my license and my acura also had a dual mass FW but i never experienced this problem even after 100's of quarter mile passes.

Now the mustang has never seen the track (nor will it) but i dont think a car with 23,000 miles should have pressure plate issues like this.

My dealer said they couldnt replicate it/that it's a normal characteristic and my mustang is made for daily driving and not high RPM shifts.

Could it be the master/slave cyl? If that's the issue i will just replace it myself.

Does your car do this?

I should say that ford and Deysha are helping me to the best of their abilities but there is only so much they can do if the dealer claims no problems.

The dealer is wrong. There is nothing normal about the engagement point changing because of spirited driving. Besides, if it wasn't meant for high rpm shifting why doesn't it redline at 3400rpm?

Is your brake fluid low or dirty?
If it is this my add to the problem.

Good Luck and hope its nothing major.

The brake and clutch fluid need to be flushed to rule out the possibility of air or contaminated fluid. The clutch shares a fluid reservoir with the brakes.

As for performance upgrades, a stainless clutch line and removing the assist spring on the clutch pedal also improve feel during spirited driving.

You're more than welcome to get a second opinion by a different Ford Dealer, pheeMc. Let me know what they say.

The fluid is 1/8th inch below the factory MAX line so it is not leaking. I do not think there is air in the lines.

Check around for the mt-82 threads.... there are many fixes for this issue. It is fairly common, but not so much at as low of RPM's as you are mentioning.... Mine used to stick 1/4 of the way down at 6800+ RPM's.... there is a clutch line replacement, fluid replacement, fluid additive, and Tremec swap. Most of the threads are in the 5.0 forum.

Thanks for the advice. i will look into the clutch line replacement. I dont want to swap my entire transmission. Has anyone upgraded the PP and solved this issue?

I was having issues with mine. Between three dealerships one said it needed a clutch which i told them to pack sand. The next found the master cylinder leaking and replaced it. I was still having issues of clutch engagement and hard shifting. the Third dealer took the tranny out for me under warranty and found the slave cylinder/throw-out bearing in pieces. Also the pressure plate bolts were loose which there's is a TSB for.
