I was advised by a knowledgeable GT40 enthusiast that I should have my new RF flywheel surface ground prior to fitting it to my engine. I was told that it makes for a better clutch engagement and a longer lasting clutch. That was all fine until I called my local machine shop, who wants to charge me $65 for the service (including removing and reinstalling the dowels). That was a bit more money than I wanted to spend.
So my question: is it worth it? What benefits come from a surface ground flywheel?
