Alex - Some good information here. Especially driving behavior notes.

Most (if not all) of the lightweight flywheels offer replaceable surface inserts, however I'm not sure they really offer that much benefit. They aren't really user servicealbe because they should be rebalanced when replaced. This means you need to send the flywheel away if you're replacing the surface during a clutch replacement, when time may be your worst enemy.

On the other hand you should be able to just take the Valeo single-mass down to the machine shop and have them resurface it. Simple, quick, and Local.

I contacted Valeo last evening. They're engaged; I received a response this morning. They haven't tested the flywheel to determine if it will accept a pilot bearing yet. I've asked them if they would test and get back to me.

For anyone interested in contacting Valeo directly here is their email address -> VT-CustomerService@Valeo.com


^ This picture shows the deep recess in the end of the crankshaft used for 5-speed applications.


^ This is a shot of the pilot-bearing installed in the flywheel for 6-speed applications. Not a Valeo but a competitors design.
