My G-Force was engineer signed off at Enklemans all those years ago by Bernie at that time. They were very practical in their approach and did thorough work. They are located in SE burbs in Braeside. This might not be so convenient to where ever it is you want to build though. For me they are 5 minutes down the road.

Englemans chased Vicroads for me at the time too, in respect of my motor options and did a good job on this score.

Worth asking if they have already engineered any FFR chassis as they might have some exposure on the beam and torsion issue.

Regardless, I'd concur that if you are deadset on an FFR chassis, have it checked out first before doing any work. Rectification to achieve the Oz standards will be easiest on a bare chassis!

Have fun doing the research.
