Yeah it's really a very slight arc, I had to look at them real close to even see it.

I still don't get why so many buggies/truggies now use spiral cut, it seemed like the consensus in my "spiral vs. regular diff" thread was that spiral cut gears will cause your diff pinion to punch through the bearing. But most of the 1/8 racing vehicles are switching over. Do they use a roller bearing now or what? How do they deal with that extra push/pull force?
