It's hard to say exactly how much faster, but at the rate I was approaching it could have actually been more than 1 sec. Unfortunately the session ended with a car off before I could press the advantage.
Just to dispel any potential driver arguments, it was my first time in the advanced group and the other driver (a neighbor it turns out) is a lot more experienced than me (drives a 911 cup car too).
So I can definitely say that the M3 is faster. And since my exhaust installation, sounds better too.
Waiting for the excuses now in 3, 2, 1...
All depends on the driver my friend, then what is a second anyway ... think about it
