OEM clutch kits. Good?/Bad?

Latemodel Rest., Summit, American Muscle all sell quality and guaranteed parts for our Mustangs. RAM is high quality.
When you listen to peoples opinion, you have to remember that its like anything else. What they have is best ect.
I use SPEC but there are the "Go To" choices: RAM, SPEC, Fidanza, King Cobra, McLeod, Centerforce. ALL GOOD~
I bought a SPEC billet flywheel and a SPEC Stage One clutch at the same time because it was convenient for me at the time.
How it is installed and how you drive is what determines good VS bad.
Hope that helps. PLEASE let us know how the one you choose turns out for you.
Good Luck!
