3.8/3.9 is generally with a 1 foot rollout on dragy & the magazine tests. Pure standing start on Dragy I get 4.1 to 4.3. Car is somewhat traction limited in first & at the first to second shift.

Car is extremely consistent on the 0-60 run. A lower treadwear and/or wider tires would drop the time 2 or 3 tenths.
