FM ND Clutch/Flywheel Happy Meal

If you need a new clutch, it only makes sense to do the clutch and the flywheel at the same time and get the maximum advantage possible. Get the best parts possible and get the FM package! Here's your package. This includes:

• Our ND clutch, which holds 340 lb-ft of torque at the crank with a near-stock pedal pressure and smooth engagement. The friction material is a steelback copper woven organic material.
• Lightweight single-piece chro-moly flywheel. This saves about five pounds of rotating mass and makes the engine "revvier" - better engine braking, easier rev-matching, and better throttle steering.  
• Hardware pack, with pressure plate bolts, crank bolts, and Loctite (red and blue)
• Pilot and release (throwout) bearings

This is a great kit for any ND, but the ND2 flywheel is the real standout here. Unlike every other Miata, the ND2 Miatas have a dual-mass flywheel. This is good because it can help smooth out the driving experience, including decreasing shock loads on the transmission. This is bad, because it makes for a heavy flywheel (19 lbs), and because they've failed (at least in other applications). However, the big reason you want to get rid of it is that it puts a big damper in the driveline, somewhat disconnecting the engine from the wheels. Miatas are all about being connected, right? We always like lightweight flywheels for our driving styles, but we really like the lightweight flywheel for the ND2.

The stock ND1 flywheel is 15.4 lbs while ours is 10.2 lbs, the ND2 stock flywheel is 19.0 lbs while ours is 14.2 lbs. 

As with all lightweight flywheels, there's the possibility of increased noise in closed-throttle, in-gear deceleration. This typically sounds like a minor rattling - a small thing that might not happen, but something to be aware of. This also isn't a great choice for drag racers, as there's less inertia so it can be a tick harder to launch. Bear in mind that since dual-mass flywheels can damp shock loads from the engine to the transmission, your ND2 transmission's warranty might be voided by installing this flywheel (not an issue for the ND1). As long as you don't drive abusively (slamming shifts, dropping the clutch, etc.) you shouldn't have any issues.
