Hey Rodney,
SPEC is the company which makes them.
http://www.speclutches.com I did a little searching over on the mustang forums and found out people really likes them (thanks Dustyn)
Your best source for more info would be
SPMotorsports BTW I talked to
Joe@Spmotorsports and he was very helpful but he couldn't match the same price as Perks.
The best part about this kit is it includes everything you need!
