I guess I was under the impression that a "normal" SL-C build was closer to 2500lbs? The last GTM I ran across the scales was 2520 lbs...and that was with full interior, sound deadening, stereo, AC, fuel....I'd suspect there are more than a few SL-C that are near 3,000 lbs. Weight is weight, but really if you are not trying to win races on a track, what's the difference between a, 2,700 lb car and a 3,000 lb car?
No doubt that there are great advantages to the dual clutch trans....but what's the difference between a 2500 lb or 2700 lb car vs a 3000 lb car? Well....500 or 300 lbs. All of that weight doesn't only effect acceleration. It also effects cornering, handling, braking. No argument that the SL-C can be whatever you choose to make it.....if you just want it to cruise around and take to car shows.....nothing wrong with that.....but if that's what you're going to do with it....then why do you need 8ms shifts?
In my mind, this sort of comes down to whether you'd rather have a '70 GTO Judge or a 1990 Mazda Miata. The Miata ain't gonna win you any awards at the car show......but the GTO sure isn't going to put a smile on your face while pushing it to the limits on a windy road.
