Depends on the driver and depends on what type of race. From a roll or 1/4 mile i'd say it's a toss up. On a course track, we've all seen the video from Japan and other videos as well on how the M3 handles so well. Now in regards to which one would i choose in terms of looks, if it's between the M3 coupe and the ISF, hands down the M3 coupe. But i'm really biased towards coupe, especially the e92, it's really a beautiful design. But between the e90 M3 sedan and the ISF, hands down the ISF.
