Miles off on both. Offset you could get around with spacers, but the PCD will require other methods. More hassle than it's worth IMHO, and while the E92 M3 wheels are nice they're not especially light or different enough to be worth the effort.
Just realised whilst writing that that you didn't say if they were the OEM wheels or not, could just be aftermarket wheels. If that's the case, could you not get them in the correct sizes?
