Pre purchase opinion on these tire and wheels used please

When I did my car I found you have few options so you end up with either custom rims or off the shelf and spacers, unless with the rear a custom rear housing and axles to fit a certain wheel and tire but the front is difficult to alter to make wheels fit.
he's running BBP, there's TONS of options and boat loads of wheels that fit.

unless he's going for max tire size, there's an "off the shelf" solution.
