Hi Andy
I downloaded the mod again over the Christmas period because I wondered if it just needed a refresh - definitely v2.5 that I'm running.
In the end, I decided to turn the fault frequency down from standard to low just to give myself a fighting chance. First race (Canada), no problems. Second race (France), I had a gearbox issue and ended up falling from 1st to 4th. My gearbox wear was only 50% when it decided to play up for a lap or 2. All other components were somewhere between 10-50% as well.
