Front too, noticed when looking at the front of the chassis pictures in the comparison images.

Will this new chassis be included in new kits, or purely an option part at this point I wonder?

I'll assume the idler gears you're talking about are the new alum ones.?
If that's the case, you going to run two alum idler gears or just one? I'm thinking that going with just one might be the way to go. As in, top shaft, plastic idler gear, alum idler gear, plastic diff gear. Basically a metal/plastic/metal/plastic setup. Just checking if that's the way to go or not.

They're velvet coated alum. I would think it's ok. I haven't had any issues but I want to try them anyway. I was looking at the metal to metal issue but it should be ok.
