Tempting, but too many variables: I'd be comparing more than just stock steelies and alloy steel-clones, but also the summer and winter tires (each a slightly different size) on them. The RR of those tires would have much more to say than the weight of the wheels.
Also, since the alloys stick out 9mm further (ET18 vs ET27), the rear skirts will have to go
This may mess up any gains I'd get from the new wheels, but we'll see. On the other hand, I'm sure that without wheel skirts I'll have less harassment from picture-takers.
