I am talking about Spacing the front fenders like this:

Charlie did it on MXBo55 and i have seen it around on other mx5's, but how is it done, is just a piece of measured up flat bar with holes the right distance apart or do they change the mounting point for the guard,
Why do i need to know? running 15x8.25 +0 wrapped in 205/50/15, i need the extra distance from the tyre
