Check out Matt's new Watch podcast at: http://www.youtube.com/watchandlistenpodcast The 2018 Corvette Grand Sport bridges a middle ground between the Stingray Z51 and Z06, or, more appropriately, provides a naturally aspirated powertrain with all the handling improvements of the Z06 body and chassis, for the ultimate in well-rounded street and racetrack Corvette package. Matt tests the Grand Sport at the historic Road Atlanta course on the optional Michelin Sport Cup 2 tire and recommended DOT4 brake fluid for track use. GM provided airfare, lodging, transits, meals, the vehicle, and track time at Road Atlanta for this review.
