Neil - I've also stuck with the original 13" wheels.
( Which is one of the reasons I needed to do some much re-shaping of the arches on my build. )
Having said that…
Wow! That is one big ar$e!
Although it looks a bit like the Sammio G-46.
Have you seen
Micky1Mo's all new Sammio Spyder?

That now has wheel skirts at the rear.
And the bottom edge of the body shell comes to a point as well.
Good luck, Paul.
PS
Love the rod.
