This got me to thinking, what is the benefit of the new ring/pinion ratio if I am gearing it to the same FDR anyway? thanks.

Edit: Also I noticed the new body fits a lot tighter around the front and back. so there is less air getting into and out of the car, this may be a big factor in my motor temps.
