Lot #657 - Known as "Obsidian," this one-off custom build by Matt Couper of Autoworks International in El Cajon, CA, is equipped with a Tremec TKO 600 5-speed transmission, fuel-injected 392ci V8 with twin Rotrex superchargers and a pair of custom intercoolers. It also features full coilover suspension, integrated tubular box frame, four-point hidden roll cage and a full NASCASR-style aluminum belly pan. Custom touches are everywhere, from the side skirts and flared fenders to the induction/extraction hood and honeycomb-mesh grille and taillight panel, which was cut from billet aluminum in a water-jet machine. The custom induction/extraction hood is fitted with billet hinges. Brembo slotted 4-wheel disc brakes are cooled by ducts on the flared quarter-panels; Couper-designed aluminum wheels are wrapped in Bridgestone Potenza tires. Additionally, the engine and firewall were pushed back for better 50/50 weight distribution. Last dyno-tested at 847hp with 750 ft/lbs of torque; 0 to 60 time of 4 seconds. The interior features custom Recaro heated seats, luxury carpeting, and handcrafted color-match dashboard and two-piece door panels. The seat boxes have been moved back to fit taller drivers - like the car's current owner, 6'11" former NBA player Dan Gadzuric. Options include power everything, plus an Alpine audio head unit with Kicker amps, XM radio, an MP3 player, iPod/Bluetooth/wireless internet capability and navigation.
