Top write up geezer! Had me cheering from my office chair...
I had a new rear on for qualifying but spent a good five mins running the engine in fifth with a wire brush on the wheel. Even that only had a marginal effect, nothing compares to two laps on tarmac.
Shame your qualifying session wasn't better as you were miles quicker last week on the trackday. Looks like brands is going to be pretty mad...
Cheers,
