Hello,
Ive got an 86 Mustang GT and Ive got vibration issues down through shifter and clutch at higher rpms (2500 to 300)usually right before shifting to the next gear.
I think it clutch related because its very unoticeable in neutral (that would cancel out HB) but yet I dont have to be moving (cancels out ujoint or drive shaft)In other words I can be sitting stationary and feel it in first gear as I rev up and slowly let out on clutch there shuddering in the clutch pedal and shifter.
Also clutch pedal is real hard to push down,from top to bottom
Called previous owner and he said he put new ford racing clutch but didnt think he did the flywheel.
Couldnt get any other info out of him Anyways my thinking is either installed incorrectly or a mechanic said something about The ford racing clutch is less absorbant then original and could be feeling things more.
Just wanted some opinions on this.
Thanks

Perfromance clutches have heavier springs (makes a stiffer pedal) and stronger friction material ("grabbier" and transmits more vibrations). As far as the shifter vibes, my son's T-5 vibrates like hell through the shifter. Son-in-law's does too. I don't like it, but all the 'Stang guys that congregate at son-in-law's say "It's normal with the built T-5".
I'm still checking into that, myself.

Yea between the vibrating and the hardness of the clutch I think for a daily driver a non racing clutch might be more suitable for me.

I had a Ford Racing clutch in mine, was definately stiffer, but if he didn't resurface the flywheel, that could be a major part of it.

OOPS! Just re-read and saw that.
+1 on the flywheel.

re surface flywheel

Replace flywheel if that doesn't fix it change clutch!

I've had the tranny apart in my car without re-surfacing the flywheel. King cobra clutch aswell. I don't think it's your problem. Never gave me troubles.
