Do 16 inch wheels fit all cars

[swizzle]

Hi all, planning to do some trackdays at some point, don't really fancy the staggered 18s on track, have seen a set of square 16s apparently from a z4, does anyone know if they will fit over the brakes on a 2003 2.5? Thanks

if brakes are standard 2.5, and it is not 2.5si they should fit.
