I'm having a heck of a time with the Mantic twin disc cerametallic clutch on my 2018 GT. I installed it the first time and after about 300 break in miles it started making an awful noise when the clutch was pushed in; but only intermittently.
I talked to Geoff at Mantic and we ran through some troubleshooting and everything appeared in order. Had to drop the trans again and videoed the uninstall and miked everything he suggested and took lots of photos and neither of us could find anything physically wrong.
I replaced the throwout bearing just for good measure (it had 2500 miles on it) and carefully and accurately reinstalled everything how it should be done (the same as the first time.)
Everything was quiet and fine at first just like the first time - but at about 50-60 miles - it came back. And it's just like it was before, again, after about 60 miles.
It sounds like this and it doesn't matter if the cars moving or stopped, when you push in the clutch it seems like the clutch discs don't fully disengage and it causes a racket you can hear loudly and feel in the body of the car.
If you go to shift during this, it will grind as the clutch discs aren't disengaged fully. The only solution is to put it in neutral, release the clutch pedal, push it back in and hope it's corrected itself. Sometimes it does it and sometimes it doesn't, making me think nothings bent. Nothings physically broken and everything's torqued correctly and exhaustively checked.
I'm gonna take the trans out for the third time in two weeks it seems.
Has anyone had a similar problem with the mantic on an 18+?
What clutches are you 18+ owners running and what experiences have you had with them?
I'm taking this out to mail it back to Geoff at Mantic this weekend or first thing next week. Jackstands and trans removal isn't a lot of fun once. Or twice. Or three times. I'm hoping to not have to do it a fourth.
