Wow, I'm pretty much speechless. This is just phenomenal, the wheels and body work is great and the overall look is just spot on I can't wait to see the next round of updates.
I saw you mentioned you were looking for more scale looking hardware for the wheels, have you ever checked out lockedup rc, he's got a few different sized scale nuts, acorn nuts and scale bolts, ranging in size from 1/64, 2/56, to m3 etc etc here's a link for you.

Maybe something there will work for you
