Have added several photos below of the patterns for our 1-Piece magnesium centre nut wheels. We can manufacture 8.5", 10.5". 14", and 15" width magnesium (or aluminium) rims from the these patterns.
The 8.5" and 14" will accept road tyres, and the 10.5" and 15" are for the track rubber. And if we have sufficient interest, we have designs for a 17" rim pattern.
Creasey Castings have cast a sample off each (front and rear) and Allwick (the pattern makers) have confirmed they are dimensionally OK. So now I have to buy a set of road tyres ready to fit to the first set of machined rims.
