A single mass transfers a bit more vibration through the input shaft and into the transmission, and might rattle the gears at idle.
More rattle and increased vibration, particularly near 2000 rpm.
This Fiat 124 Spider comes with a 1.4 Turbo that has some torque
low down. That's why Fiat decided to use a dual-mass flywheel.
Clutch feel is essentially the exact same.
It
may cause worse shifting. A sprung clutch disc is heavier than
the rigid disc (as used with dual-mass flywheels). The clutch disc
sits on the input shaft and this mass has to be accelerated or de-
celerated by the synchronizers. Elevated mass = harder job for the
synchronizer assembly. Result: harder shifting.
IF this Clutch Masters clutch is intended for tuning or racing use
I'd bet it's harder to operate. I had a ZF Sachs Racing clutch and it
was grave harder to use. No joy in heavy traffic.
In the cabin you likely won't notice it at all except for an auditory change.
See above. Between 1500 and 2500 rpm it's normal to perceive some
vibration through your steering wheel, your seat, your pedals.
If I had the option I would never, ever, put in a dual mass flywheel into a
car I owned. They are not durable and require gimmicks like clutch delay
valves to prolong life.
Relioable or not - it depends on the particular car. That said it's
fairly easy to remove a CDV even while keeping the DM FW.
Typically the aftermarket provides better options for a sprung clutch that pairs perfectly well with a single mass flywheel.
Except you own a 124 Spider.
The rest of the time, you probably won't notice any difference.
This is just a guess. We both don't own a Fiat 124.
Vibration is eliminated by the springs in the clutch disk. So as long as you don't choose a solid "racing" clutch disk, you won't have any significant vibration.
No no no.
'Eliminated' like a dual-mass flywheel? Never ever.
Also as mentioned above, drivers generally prefer the crisp feel of a well chosen conventional clutch setup.
Honestly, I have sympathy for single-mass flywheels, no CDV gimmicks etc., but
a well designed dual-mass set-up is smoother. Let's keep true, fair and square.
