This Clear Springs Run is a point-to-point on asphalt, and it is worth 180 Points towards the next Wristband and a purse of $12K to the winner (not including bonuses).
Restrictions for this race are Class-S or below cars that are manufactured by Aston Martin.
If you have been winning all along then you will unlock the next Wristband with this race victory -- before you head to Race Central to claim it though, it would be an idea to finish all of the other Orange Class races.
Don't worry, you still get credit for them, and you get them done which is even better.
At this point you should be picking off the popularity numbers and approaching the next Showcase Event -- that and the odd Achievement or two. Keep up the good work mates!
