Got the car back today from vette dr's, mantic 9k installed. Great job & fast service.
Getting used to the lighter flywheel combo from a dead stop, but it drives fine overall. There is a decent amount of chatter at idle, not really a deal breaker for me since Ive had lots of chattery puck clutches on other cars. But most of you say your mantics do not chatter so Im just wondering if it will work itself out?

I still get chatter but only when pulling out on an incline, weird. I have to slip it pretty hard to get it not to do it. On level surfaces its fine.

What is the difference in taking off with the lighter clutch?

its harder to do it smoothly, you have to rev a little higher to avoid getting a shudder. With a stock clutch & flywheel I can easily let the clutch out to the grab point, let it start rolling, then give it gas and take off smoothly. Its hard to do that on this clutch, but I knew it was gonna be like that. It should get a little better as the discs get broken in.
My other problem is my idle tune needs to be touched up. I dont know if its because Im cammed, but ill start the car & it will just die, not even letting out the clutch. I have to give it a lot of gas to keep it from dying about half the time. This doesnt help with trying to take off smoothly either. My friend is gonna touch up the tune this weekend.

The tuning will help with the take off. Most people who have reported a shudder to us also say it went away after some mileage is put on. More then just the initial break in 500 miles. Hope that helps.
Just wondering why to use the GM throwout bearing on the RXT with Tick master? I had mine done by a shop with a new GM slave, but I don't know which TOB they used. Should I expect failure in another few thousand miles?
update, my friend adjusted the tune under 1200 RPMs.. I can now do 3 point turns & get in and out of parking spots without stalling 20 times!
He played with something on the air table.
Got 300 miles on the clutch, cant wait to hit 500 so I can enjoy the car to the fullest.

Willing to share the before/after? Just curious to see what was changed. I'm trying to learn

I only have 400 miles on my new Mantic 9000 and like it A LOT. I had a RXT in my 03 Cobra and was not very happy with the engagement feel and the amount of chatter is had in traffic. I would recommend the Mantic to anyone that likes a stock like feel but makes good power.
I hit the 500 mile mark today, so I decided to open it up a bit, shift at 4.5k now instead of 3k. I also revved it up to 6k a few times without shifting and just let it coast back down. When I rev over 4k rpms with more than 1/4 throttle the shifter vibrates/rattles like crazy. It does this in neutral too, but not as bad. I have an OEM shifter, never had this problem before the clutch.
I took apart the center console to see if I could find any obvious culprits.. looks like the shifter isolator is ripped/cut off completely so Its no attached to the shift lever anymore. Is this piece supposed to keep the shifter from vibrating? Everything else looked ok as far as I could tell.
