Crewman.. Best Advice for 1/12 racing. I would recomend green springs on both sides. If the track is sorta large and flowing I would use a red on the + side. All posted brushes are great choices. The 99+ brush from Trinity is a great brush for power and many runs. If your looking for more endurance and good power the 767 with a hole is the best choise as those brushes are slightly harder and wear a little longer.
Hope this helps..
If you need anything we do have all brushes in stock...
