Bought a 22k mile ‘03 C5 Z06 in September. Car is crazy nice of course and still smells like a new car inside. I drove it home on original tires for instance. It’s an untouched car that needs drove. I bought this for my 18 year old son actually, so I know it will see some miles. We’ve done the usual corvette C5 stuff such as replaced the EBCM, new ATI damper, oil pressure sender, etc. I picked up a set of ARH 1 7/8” headers with catted x-pipe from Tony Mamo shortly after purchase. While talking to Tony, I asked him about his newest clutch offering, the lightweight Mantic 9000 twin. Good timing, because my son gets home from school and tells me the slave took a dump, as the clutch pedal stuck about half way up, on the way home. It needs a slave, but I’m not about to even consider replacing the slave on a C5 without throwing a clutch at it. Call Tony back, and it’s on the way, along with a new OEM slave. I went with the ceremetallic version. Tony also offers the lightweight unit in an organic version if your interested in that. How about some pictures…
Heres what comes in the package, even the ARP bolts. It’s a work of art for sure. Tony has Mantic zero balance the entire unit. This eliminates the dreaded shifter rattle in C5/C6 vettes, and obviously helps with harmful harmonics that will rob power also.

My new OEM slave I bought with the kit. Also put a 3’ speed bleeder in the car. Because it’s a corvette. If you’ve never tried to bleed the clutch in a corvette, you won’t understand.
So here’s my take on the new MMS Mantic ceremetallic twin, offered exclusively through Tony Mamo at Mamo Motorsports…
1. The clutch pedal feel is a little harder than the LS6 clutch was, which is good. No more “wet noodle” clutch pedal. You actually have some pedal feel with this clutch.
2. I did NOT shim this clutch and it grabs about right in the middle of travel maybe…maybe 1/8” above factory location.
3. ZERO chatter. Clutch release is smooth. No jerky uneasiness or surprises here. It does what you tell it to do.
4. Clutch pedal window is as wide as stock LS6 clutch. It’s not an on/off switch. It’s just as wide as stock. I can slip it for days without issue. I did NOT change clutch master, only the slave.
5. My son is 18 and been driving a stick since the summer. If he can drive this, then anyone can. My mom could drive this car.
6. Moment of inertia is much lower so the engine really zings up and back down quickly. I haven’t touched the tune yet, and it’s ok. With a little tuning here, it will only get better.
Tony is a gentleman and has the best customer service in the industry. His reputation stands alone in the industry and he will go way, way above what it takes to make sure your completely comfortable and happy with the purchase, not only of this clutch, but any of his products he offers for that matter. I recommend the clutch highly, if your remotely interested in a lightweight, yet extremely driveable clutch setup.

I obtained the same Twin 9000+ Ceremetallic through a local dealer for $1800 in 2020, surely they have gone up since then. I have granular weights somewhere but all I can find at the moment are my overall totals; 30.75lbs for all except the flywheel, 15.5lbs for the flywheel. No photos of the James Bond case?!
Lol…I knew someone would ask. It’s a one owner ‘87 step side that I built for my brother. He commissioned the build of course. He bought it new. Custom ordered it with step side bed, 350, 4 speed manual, A/C, midnight blue paint, G80 rear end. It was $14k and he thought he’d never get it paid for. I drove it to school once in ‘88. It only had 6” lift then on 35” Ground Hawgs.
He’s got more money in stainless socket cap fasteners…pretty much every bolt I could possibly change out on the truck…than most folks here put in their engine build. It’s nice. 58k original miles.

Jim, I’m glad you posted up. That’s excellent data to share with the community here on just how light the MMS version of this clutch is, compared to a standard Mantic 9000 twin. This flywheel is aluminum, and has much bigger windows in the outer ring gear portion, where rotating mass isn’t needed in a performance clutch setup. Tony spent 6 months with the guys at Mantic, who all happen to be good friends by the way, going back and forth on a design that would suffice for this new venture. This things screams performance and backs it up once installed.
I didn’t get the fancy aluminum briefcase with this unit, and that’s ok by me. It wouldn’t help my cars performance in the smallest bit. 😜
