yes, you all are correct, at those speeds the aero really come into play. The front doesn't feel as planted. I'm not so worried about the back. That is one of the reasons that i didn't get a chance to do a vid, it gets kind of windy here in the fall, and with wind, i hesitate to go over 180mph.
What are the gears on the M3?
I have stock 18's, and it's a 6 speed manual.
While yes i agree speedo is not an accurate measurement, it's still nice to say i hit 200mph... I'm most certain that i am officially in 300kph club (GPS), which is already cool!
