Depending on the offset and backspacing etc it will change the steering gemoetry. Another thing to consider is what type of wheel you are going to.. are you sure there is no bolt on application or one close? The Le Manns Tigers ran splined hubs with 15″ knock offs, as did the Frazer tiger. I would think you could investigate the alpine splines, but maybe they are not strong enough.. perhaps investigate cobra, aston hubs?
