GMP Performance of Charlotte discussed performance, handling, and safety upgrades available to Porsche (and other marques) owners through their partner Harmony Motors, including tires, wheels, brake fluid, driver restraint systems, and suspension and engine parts. For more information, see their website or talk to Harmony's service staff. We knew this would be an interesting meeting, so we begain it early, but many were still involved in discussions in Harmony's shop area after it ended.
