Hi Jack,
Hopefully someone in your class will chime in. We have not raced on this track yet (Thunderhill West using the bypass), but I found out that the straightaway is 4/10’s of a mile long. For comparison, the straightaway on the East track from turn 15 to turn 1 is 6/10’s of a mile long.
Come on NCK, help this new member out!
El Presidente has told me, “TaG should be a 4.8 to 5.0 final drive, 125 shifter should be 19-22 or 23.”
