    I only have books for '02. I can give you those specs but have no idea what changes were made from '98 to '02. Let me know if you want them.

    You have to remember -- I'm an old guy. You posted your reply after my bedtime, so I'll have to look it up tonight when I get home. Sorry...

    lol it's okay. i will wait patiently

    i'm asking bc my flywheel was pretty scuffed up ... a guy in my class took it to his work and machined it for me ... he had to take a LOT off and i can't find specs anywhere. i suppose i could shim it and it'd be back where i started before i tore the car down but i'd rather be safe than sorry since i have it torn down this far

    Under the Engine Flywheel Cleaning and Inspection section of the factory service manual, it states as follows: "In order to maintain the proper component balance, contact surface taper, and heat transfer, manual transmission flywheels are NOT to be machined." As such, no specs are provided.

    Exactly. Replace, do not resurface the flywheel.

    Won't tell you that in the owners manual

    You would need to reference a shop manual, which doesn't come with the car.

    Has the similar effect as a worn disc; shallow flywheel or thin disc = less clamping pressure.

    The hydraulics only move so much and a machined flywheel moves the clutch away from the slave
