2020 XRC Turbo RR
Option 3: Neither the machine or the belt require special break-in procedures and just drive it normal.GBoost has a new Race belt that's likely to be all the rage soon, otherwise I like the Worlds Best. There's two trains of thought to the "break in". One is the machine doesn't need one but the belt does, and the other is break the machine in like you're going to drive it, and call that belt a sacrifice piece.
I went with option three and replaced the OEM belt at 1300 miles.
