That's true, The Challenger HC is as aerodynamic as a brick, but I would hate to raise it 2 feet & add 3k lbs. to it, with 100 lb. tires. The TRX has 100 lbs. of skid plate too.
Another guy at the track last night just bought a TRX also, he removed the skid plate & ran 12.40's @ 108 mph. Still had paper plates too. 300 miles on it.
