Like new dual ceramic high performance clutch for mustang gt fits 15-17 for sure and many others as well . Ran for about 2 weeks and was very carefully broken in . NO ISSUES AT ALL! FULLY OPERATIONAL and ready for install . Beast of a clutch and has a lightweight pedal feel . Just a little overkill for my set up . I swapped it out when I did my new aluminum flywheel .. was going to put the RXT back in later when I go forced induction. but thats on hold for now so.. The RXT is the dual ceramic version it grabs harder and is a lot more durable than the RST version. It is capable of handling up to 1000hp . Paid over $1000. Usd plus shipping..my loss is your gain .
