Don't forget the centerbore, which is huge on Mazdas and smaller on SUbies - the wheels won't clear the hub bore without machining. Rota is supposed to have a wheel that'll fit (Tarmac) but you have to special-order the hub bore to fit. Rishie sed to do this, don't know if he still does... I'd be interested in a set of 17x7.5 or 17x7 Tarmacs in steel grey, but couldn't find em to fit...
