Rear End
Tires: Pink
Shock Shock: Green Springs, 20wt oil
Body: speed 8/9 or Yokomo MS1

Grey works sometimes but I will try Pink, normally on asphalt you will run a tier in the pink family, why not try Yokomo L tiers that are what Masami runs, 6 cell well you have power in that car, consider dropping to 4 cells and a 10x2 motor

Don’t know what t-bar you have but I will try the 0.63 Ass. (Side Spring: White) and may try blue side springs

Rollout Brush less: as far as I know it should be geared as a stock motor, hard.
