Very nice piece of kit. Still can't tell if Spring Steel is being used or not. One thing I was not clear on: does the car come with a front diff or one way? Will both be included, or will the diff be an option? Is the option for the solid axle included in the kit, or purchased seperately?

And on the .08 pitch gears. Having only used standard gearing, I know the general rule of thumb is to have the sum of the pinion and spur for both 1st and 2nd to match for the mesh to be correct. But it looks like the pinion has a 5 tooth spread out the box and the spurs around 7. How does that work?
