The AWD gearboxes have the following ratios.
4.21, 2.49, 1.66, 1.24, 1.00
Final Drive: 3.23
So not the best torque multiplier but pretty decent. Since Open Light is HP limited the lack of proper rally differentials, active centers, and such that make nothing other than an Evo or STI competitive in Open Class is not as big of a deal.
Weight is my biggest question. Then again, my E36 race car is under 2700 without much effort and started around 3100. I think E46 RWD cars are around 100 pounds heavier by specs, AWD ones another 150-200. So hopefully maybe in the 2900s for rally spec?
Cool car. I keep my eye out for one to build for Open Light around here.
