The main reason for the wider chassis is to accommodate larger fuel tanks and different radio and battery boxes. If the stock components are used the current chassis dimensions are fine.

It doesn't necessarily have to be wider for the production run. The main reason that I asked is that I wanted to know if it would be possible to order a custom one. I probably should have waited until you had the first one made before I asked. Sorry for the confusion.
This will be for a project that I have in mind and it can wait until after you have satisfied the majority of potential orders.
