Just because a car can run 15.5 in magazines doesn't mean YOU can drive it that fast..............
It's a harsh fact, but true.
Seriously though, LACR may be 2500ft (or 2000ft....somewhere in that range), but I happen to know you don't lose a full second off our 1/4 times until you are above 5000ft (I know some people in both Denver and Albequerque (that fucking place in NM)).
