Oh, the plan is to definitely keep it rear motor. Mid motor would require some gnarly cutting that I'm not fully willing or capable to do.
That said, the term "franken buggy" got thrown around a few times, but I disagree.
B5 front end from the front arms to the wheels. This is purely to make the front arms more durable and so I can run hexes on the front.
The rear will be entirely B3 except for the hubs and axles, so I can run rear hex.
