Hi - i am lucky enough to own a fairly quick 968CS, and an BMW e46 M3 SMG individual too. Have also driven a fairly modded e46 M3 track car around Bathurst Circuit club racing, and it was back to back with my Porsche.
They are chalk and cheese. The M3 has a stunning engine. It is a much faster more powerful car, and that engine does offset the weight it carries on the straights, so i think the m3 eats the 968 in a straight line with both being in stockish NA form.
That however leads to weight. Unless the m3 has been stripped, it is a beautiful road sports car, not a track car. It feels so so heavy on the track- like a barge relative to the Porsche on corners. I am impressed how fast lap times can be in it given its girth. Then again a dozen or more speakers, tv etc will do that. The Porsche by comparison is wonderful on the track into, through and out of all the bends and monsters the M3 there.
Great vid and driving. A good mate and i race in an almost identical fashion, he in his M3, and love the fun lap after lap. He's yet to get me though....go the 968!!!
Thanks for sharing that vid Erik.
