At Ferrari of Seattle, clutch replacement on a 360/430 is $8-12k, depending on whether the flywheel and a few other things need to be replaced. You can save a few bucks by taking it to Ron Tonkin in Portland. Probably it’s cheaper in markets with more competition like SoCal.

I think most markets do not have an any independent shops which have the SD2/SD3 computer which is necessary to talk to do things such as configure the clutch after replacement. Seattle does not. As far as I know, the closest indy with such a computer is in the SF area (1000+ miles away).

I have an F430, which is a slightly more sophisticated, reliable 360 (but not by much).
