I was thinking of swapping the tyres as they're 205's, but seems a waste when they've got good tread on them.
No Idea on the offset,only just got into playing with cars after playing with bikes. Th zxr's moved to derbyshire now though. Also realised I dicked my calculation up and 15mm each side should clear it.
I hear that using spacers wrecks your wheel bearings though?
