Hey, it only took 9 laps to get on top. ;-))
We are running twin 45 DCOEs. Getrag 245. Racecraft builds their own BMW diffs with preparatory LS ramps.
Most of the 356s racing in vintage races have VERY strong motors; coupled with no weight and better aero they can be tough to beat. The 1800 handles much better and has more torque. I just have to remember to downshift all the way to 2nd every time for Turn 11. 😉
