Anyone using a lightweight clutch for AX?, feels like an on/off switch Options

[nine14cats]

Is there anyone using a lightweight flywheel / 4 puck clutch disk for autocrossing? My new track car has one and I'm not so sure my wife is going to like it. I had heard they are like an on off switch and I have to agree after driving the car. Getting the car onto the trailer was an experience.

I'm worried about longevity as it takes quite a bit of slipping to get a smooth launch.

In my last car I used a Centerforce setup which was easy to use.

Thanks,

I haven't used one, but one thing to consider is why the flywheel is there in the first place. Energy output from the cylinders comes in concentrated bursts, and the (moment of) inertia of the flywheel helps smooth those bursts out. I remember reading that on certain Hondas, a lightened flywheel meant a fairly predictable (catastrophic) failure of the oil pump gears. I don't know how TIV engines respond, but its probably safe to say that the increase in pedal response comes at the expense of shorter engine/tranny life. Anybody have first-hand knowledge, BTDT ?

Of course, if the car is strictly for AX, this might not be a major concern.
