How fast, in terms of 1/4 mile times are the stock M3's (E46) at high altitude, particularly in Denver? I'm not a fan of going off 1/4 times from magazines. I can extrapolate estimated quarter mile times to a certain extent based upon the 1.0781 ET / 0.9282 MPH correction factors for 5800 ft. If I take 13.3 @ 107 mph, and add in the correction factors for 5800 ft, I get 14.34 @ 99 mph. I'd really like to hear from anyone that has actually seen this car run at Bandimere in stock form to see if my estimates are reasonable. Since the M3 is typically good competition, I figure someone knows what they actually run up here.
