Which wheel do you have on the car to start with?

Series 4 can be found on mostly three wheel types.

1. Radial spokes https://bespokes.co.uk/wp-content/uploads/2018/07/morgan-aero8-hire-1024x682.jpg
2 Twin radial spokes (a.k.a. Aeromax 19" wheels)
3. 6 radial spokes https://ag-spots-2020.o.auroraobjects.eu/2020/11/04/morgan-aero-8-series-4-c607004112020185012_1.jpg

One or two did have the speedster wheels fitted I think. https://media.evo.co.uk/image/private/s--6PBaEhfD--/f_auto,t_content-image-full-desktop@2/v1556263773/evo/morgan-speedster-ftq-static_0.jpg

Everyone loves a Morgan. Even me, unless it's broken again.
