MAPerformance 2011 Sport Compact Proving Grounds @ BIR – Event Details

[Shane@DBPerformance]

Quicker than 11.5 is supposed to have a 5-point roll bar. Quicker than 10.0 or faster than 135mph is supposed to have a full roll cage. It's comes down to the track and officials that day, unfortunately it isn't up to MAP or whoever rents the track. I think they were even giving MAP some grief last year at their own event over some lessor rule.
