Flywheel Poll, Choice of flywheel for my swap Options

[97lestyousay]

Aluminum flywheels have steel friction surfaces and gears for the starter... So stop worrying about the aluminum being suited for those purposes.

Two piece anything u are accumulating tolerences. If the pieces are both +/- .001 like the 1
piece shown above, now you have +/- .002.

Edit: I realized that when he said the Manufacur and looked it up. Look up

I just wanted to add my 2 cents...

I don't reccomened EVER getting an alluminum flywheel over a billet steel flywheel for a car you plan on driving hard. To start... aluminum flys are lighter, but because they are made up of multiple pieces, this hurts their strength greatly. Different grades and different types of metals heat up at different rates and expand differently, and there have been a lot of reports of aluminum flywheels failing during hard race-type driving. We've had a fidanza aluminum flywheel shatter in one of our race civics, and it's not a pretty sight. On the other hand, they typically are lighter, and are cheaper. I've run personally 2 different billet steel flywheels in my ae86's and have never had a problem, even in very hard driven situations. They aren't significantly heavier than an aluminum flywheel (Toda flywheel was about 9-10 pounds, Jun flywheel was about 10-12 pounds) and they are much much stronger.
