I don't know of anyone off hand in the UK running the same width all round (other than on standard rims ). However, there are many who run this sort of set up in the US. Try my350z.com or 350z-tech.com (search first or you will be flamed!) and see what those guys are running. Or PM Adam at Z1 Performance (one of our traders) - he will know and is a good guy so shouldn't mind giving out a little free advice.
