Thanks mate. S54 would be a great option I would think, and as you say there'd be plenty available compared with the S62 or S38 I would have thought. Plus it would retain the six-cylinder theme of the E34 M5. an M- V8'd E34 would be awesome though
M Parallels are the go I reckon:
I was looking for these for my E38 but I'm pretty happy with the style 69s that are on the car at the moment. Same fitment, 8" front, 9.5" rear.
Plenty of Mpar's available overseas it seems, but postage is ridiculous.
