18" alloys on a calibra turbo

[col16vturbo]

Hi guys
im thinking of getting meself a spanking new set of alloys for my cally t and have a few questions that hopefully you damn fine chaps can help me with.Firstly will a set of 18" fit without any problems,and secondly will there be any suspension geometry issues,ie camber,that can affect the transfer box or general handling characteristics?.Also can anybody give me the correct wheel sizes,ie offset,pcd etc, that will fit comfortably?
cheers
