I had talked to harold at HP autowerks about this same idea. He has/had them in stock and said they fit. They were something like $20-30 for the brackets and two piece bushings. I went ahead and ordered the M3 bar too since it was only $150. The M3 bar is the same diameter in the bushing area as the 135i and 335i front bar, but the M3 doesn't neck down to a smaller diameter in the center like the other two. It should be much stiffer. We shall see...
