Driver said car would not hook up, and estimated "the 12s" if the LSD was fixed. PERFORMANCE: TOP SPEED * However fast the thing goes before a.) the engine grenades from overboost or b.) the aerodynamics of the car take on the characteristics of a hovercraft. PERFORMANCE: LATERAL * Reasonable: I can generally run with "Super Stock" 3rd gens if they have average drivers, but can't keep up with the two national class 3rd gen drivers in the area.
