Advice re wheel offset

Will a wheel with 43mm offset cause problems on a car that has 39mm as standard? PCD and hub is perfect but the offset thing has me stumped.

Cheers

4mm shouldn't make too much difference; might change the steering feel a little. Is the tyre width different? Might effect your clearances.....

No width is the same - 5.5j x 14". Basically alloys from a 145 (Original Boxer engined one) to put on my Sprint

Aha - got it now. The greater the offset the nearer the centre of the car the inside edge of the tyre would be. I thought it would be the opposite. Those wheels will NOT be getting bought for the Sprint even though the difference will only be 8mm. There is a cracking set of 145 alloys at the scrappy in Lochburn road Glasgow for anyone interested (will pick up for someone if need be)
