The FM Happy Meal includes a Flyin' Miata clutch and Flyin' Miata flywheel, along with a clutch switch override, pilot and release bearings. You get to choose the specification. The Happy Meal will fit any 1990-05 Miata, including 1.6 engined cars.
The FM Level 1 clutch is rated for 318 lb-ft of torque at the crank, and is perfect for Stage 1 or Custom Spec kits with relatively stock engines. It's a real sweetheart, offering near-stock pedal pressure and smooth engagement, but it's strong enough to cope with anything stock engine internals can put out.
Our Level 2 organic clutch has a higher pedal pressure and higher 353 lb-ft torque (at the crank) rating. It's probably stronger than the transmission, and we have not yet met a 4-cylinder Miata that can make it slip.
Both Level 1 and Level 2 clutches use the same disc, with friction material that's a steelback copper woven organic material. The pressure plates are different, which gives the heavier pedal pressure and increased torque capacity.
The Level I clutch (plate and disc) is about 11.75 lbs, for a total rotational weight of about 22 lbs. The Level II clutch is about .5 lbs heavier.
The lightweight flywheel may cause some harmless drivetrain noise on closed-throttle deceleration.
We recommend bypassing the starter interlock on your clutch when installing a stronger pressure plate. This allows you to start the car in neutral without putting your foot on the clutch and your thrust bearing will appreciate it! We have a cool little clip that makes this easy without any wiring - it's included with the kit.
We strongly recommend replacing seals while you're in there - they don't go bad too often, but it's a big job to get to them! We also strongly recommend using our installation tool with the rear crank seal, to ensure that you don't cause a problem that didn't exist. Plus, the tool is less than a new seal. Also, please be aware that 5-speed transmissions need the transmission input gasket, but 6-speeds do not.
What's the toy? A clutch tool!
