Hi I need wheels with an ofset of ET18 with ford siera PCD has anyone any idear's as any help would be welcome.Regards Arthur

No idea but I do know that STM used to use 14" wheels for the IRS STM chassis as that's what I've got on mine (though don't ask what because I got them from STM direct- just some 14" clones).

My Minilte replicas are 23ET so them and a 5mm spacer will do it.
Try midland wheels

Quick question on the topic of STM wheels, are your 4 or 5 lug, I have 5 lug and everyone seems to have 4 lug.
