My opinion on this is that the run offs can help time and hurt time, if it does not red lap then no reason to not use them. However, if you will be testing, all cars should be given equal access to them. There are at least three corners on track where running a little wide helps these cars on exit, but be careful as one seems ok but if you go too far it will red lap. My best lap had extra run off on exit, believe it would be the first turn of the National course, pinching the car down would loose 3-4 tenths according to the following laps. Should try not to go too far off, I still had the inside tires on the rumble strips, which can upset the car in some sections of track. Anyone have an issue with this statement? @Motor City Hami - your in Sir, again, glad to see you join in. Rules are a little different but the cars are so close at these specs, both have 1 issue each they struggle to get removed. Will be interested in how they get approached.
