I just grilled my contact again, and he is adamant that at the driver's dinner on Sunday night, Steve Ellery's father/manager was really pissed off and told him that was because of the suspension for Phillip Island, due to a wheel nut coming off in the main straight.
The only thing is, between Sunday and now he may have successfully appealed the decision, because when you look at the footage the rim was cut in half, which probably happened because of a rock or the like getting caught on top of the caliper and grinding it's way through. This would certainly cause the wheel nut to come loose and fly off.
But apparantly the officials are going to be really hard on loose wheels/nuts this year and it's quite obvious that are willing to dish out race suspensions.
Please remember guys, that I am just letting you know what I've heard, don't flame the messenger.
