So nobody really hit that speed with his 330ci ?!
To be ownest I was thinking about removing my side mirrors and wiper blades. Usually tires are not a big issue for a short burst run. A well balanced tire will stay stable at 60 mph and 200mph. I am more concerned about the wheels and tire size.
Suspension is not a big issue. It will just get 500lb more load. It should be able to handle it on a smooth surface.
My concern is how the 330ci handles at 170mph when I move the steering wheel 1/32 to avoid a bird ...
I have a 5sp tranny and an unlocked computer so at 6500rpm I should hit 160-170mph.
