Racing Beat Flywheel upgrade

If you have to let the clutch slip more, then it will wear out faster. Slip = wear.

For a non-turbo, it's a good debate.
Cons - when the aluminum *insert* wears out, it needs to be replaced; you need to engage the clutch with a little bit more finesse; light load cruising might be irritating cause of slight lean surge
Pros - noticable faster revving, especially in neutral
I don't like the fact that it's another wear item.
The lightened steel one is good enough, and it'll outlast the car.

For street cars, I'd recommend a lightened steel one.
You can argue for an aluminum one if you're racing.
I think an aluminum one is a PITA for street.

I had an SR al and ACT Extreme PP and stock disc many many years ago.... at the time I LOVED a stiff clutch. It was completely unnecessary for the amout of power I was making, it was a personal preference. I didn't think it was a PITA for the street and once I got used to it, it was fine. There wasn't really much jerkiness associated with it, but on hills, you really had to rev the engine up to get moving.

Then I fucked my knee up, severly and royally screwed it up to the point were 66-75% of the cartilidge in my left knee was surgically removed. THEN the clutch became a pain in the knee.

When I needed a new clutch I went with the exedy twin disc because the pedal effort was less. Not nearly as close to stock as they claim, but it was less. It took the same amount of getting used to becuase of how grabby the twin disc is.

Yes and no, if you can drive it properly, you won't be slipping it that much more than a steel or a stocker. Once I got used to mine, starting it on a flat was no different than a stocker. The inertia, or lack there of, was most noticable on the hills.

It's personaly preference to me. An AL one with exagerate all the pro's and cons of a steel one over the stocker. Faster revving, more rev's needed when starting esp on a hill.

It's certainly not like driving my truck, I can feather that clutch without touching the gas and get going from a stop, while towing, standing on a hill. Lot's of torque, heavy flywheel, stock clutch with 160k on it. The big thing is the lack of torque that a rotary makes low in it's RPM band. The heavy flywheel is there help compensate for the lack of torque and to make the car a little easier to drive.

True, but again, if you can properly drive it, you won't be slipping it THAT much more.
