I looked at the Black Arrow website and see they offer body kits and lexan interiors, so how about building a new lightweight, robust, race ready body, rather than spoil your efforts on the 'show' body...how hard do you think you would be able to race that 'show' body?!

The diamond pod layout seems simple but inspired, is it unique to BA? 

How does the adjustable motor positioning work? How rigid is the motor held once you get your optimum set up?
Does suspension 'harm' a car raced on wood?

Racing limited edition coollector versions and show bodies is how I roll 
I don't have shelf queens. Maybe just some "ladies in waiting" ( waiting to see the track during lockdown )  

Lightweight interior and crystalwork will probably be fitted at the time that the body is repainted after some hard racing.

The sliding motor is enabled by elongated motor screw slots. Low tech but effective.

Having a single front pivot is common (NSR, Thunderslot, Avant, scaleauto and others) but a single centre rear pivot I've not seen before. 
Having body mount points along the centre line (with set screw body balancers) is increasing in popularity. 
Even NSR is starting to design cars this way. Maybe centre line motor mount points will also grow in popularity. 
Many believe that suspension is only good for soaking up bumps on bad plastic tracks but for me that is not the whole story. 
Suspension enables and controls weight transfer during cornering and has an impact on handling irrespective of the smoothness (or not) of the track.
