Just a reminder per the rules how the final round and overall points will be awarded.
At the end of the series in the overall standings the worst results per mod and per driver will be taken out. This means that in the overall standings per mod you will have 4 results that count.
In the specific mod standings all 5 races will count.
Regarding final race penalties:
So final race penalties will be handled like this, after final race we'll convert all given penalties to specific time pens,
Drive-Thru equals +30 sec added to race time. Last Row equals +15 sec added to race time.
So I'd suggest to be very cautious on your opponents in final race - if you'll be found to have caused an incident, it may cost you some position in the race result - and probably even in final standings.
I'd like to remind that even if for example you have caused your opponent to spin, giving back the inherited position can much help avoiding to get a penalty.
Good luck guys in the final round at Grand Valley.. There are several guys in contention for final podium positions in all the series.
