Thank you MrT.
I see your point with 14" wheels. I went through wheel threads few times as I know 14 would be a better option. However I have few sets of 13's and it would be a good idea to utilise at least one of them.
Tyre on the wheel in picture is 165/80/13 and it's slightly bigger then standard spitfire wheel.
Last year in excitement I have bought nice wire wheels but then found out that they would not fit spitfire (came off Jaguar) so they would be for next project if one arise
More progress later today...
