    Calculation of clutch wear percentage for Ferrari 360/430:
    Auto-calibrated closed clutch position - NEW closed clutch position / Clutch thickness (8.5 mm for 360, 5.6 mm for 430) * 100 = % wear on clutch

    So 12 percent worn for a 430 or 8 percent worn for a 360

    I think you see the 2.38% clutch wear index and are assuming that's your wear. That's tempting, hehe. But Mello and Flash32 got you on the right track there.
    An excellent detailed description of what the Clutch Wear Index is can be found here:https://aldousvoice.com/2014/08/07/ferrari-f1-clutch-operation/
    However; he doesn't address the number represented as a %, so I can't help ya there.

    Using Mello's formula (Auto-calibrated closed clutch position - NEW closed clutch position / Clutch thickness (8.5 mm for 360, 5.6 mm for 430) * 100 = % wear on clutch), and an Autel ODB report from my 2000 360 F1, is this the correct calculation and wear percentage?

    Here is the Autel report. Am I using the correct data points?
