This is a Bunker Dirt Cross 4-Lap Circuit Race on Mixed-Surface that is worth 210 Points towards the next Wristband, and $15K reward to the winner (not including bonuses).
Restrictions for this race are Class-A cars or below.
There are a lot of races in this series -- more than in any of the others -- but adding a few additional races seems to be a pattern here.
Technically you really do not need to clear all the races from one series in order to race the next series, but doing so helps to de-clutter the map, and provides you with opportunity for gains in money, popularity, and fun! But mostly popularity, of which you can use all you can get...
This track is very drifty and fast -- short too -- but that is OK since it has 4-Laps for you to position through so basically you are best served in a car whose drifting abilities you are comfy with. Once you beat your way through the pack and take the lead it is you against the road!
Oh, watch the last turn before the end as staying too close to the inside can get you surprise air, which considering you need to turn right ahead is not so good.
