This is one example , Joe Achilles in this case where the rear bias is mentioned
Obviously have no reference where he has got this info from but just a guess is that as this was a bmw press event where he borrowed the car, it may have been mentioned to him in a briefing potential tially?
I love these technical discussions, it’s what it’s all about!
