M3 vs. GT3 weight difference
So if I have the correct figures, when you come right down to it our new M3 will weigh about 600 lbs more than the current GT3. Is this correct? So if someone was inclined to spend the incremental money and send off to Dinan or some other after market firm, how much weight could be knocked off the 600lbs differencial? All estimates I realize, but I'm curious of the thoughts/opinions of the more knowledable folks here on what is achievable.
