As mentioned, CRC Purple fronts and CRC Magenta rears are excellent on this track. Paragon FXII early in the day and Ground Effects when the traction comes up.
As for gearing (13.5t 1s blinky), with 46mm tires I run a 72 spur and 47 pinion, the gearing mentioned above may be intended for a 17.5t motor as that seems extremely high.
