Are you AWD? What tires are you using and on what wheels? Very impressive 60fts. These times are spot on with all of the other n54's out there except he's able to get his 60fts so low to get high 11 second passes. All the 2.0-2.2 60ft 335i's out there hitting 12.0-12.3 @ 116-118 would be running these times if they could launch like this guy.
I am guessing its awd and/or has lightweight wheels with extremely sticky street tires (flirting with drag radials - not slicks).
