This maybe a question that can and can't be answered but I've been looking at a wider arch kit for the MK3 fiesta, the orignals are no longer wide enough.

Im not after some after market type universal type ones as they don't suit it.

Im after some like on this rally fiesta, don't have a clue who owns it or if anyone knows the owners, builders but I'd like to get a set from them, or ones just like them. Struggling here.
