Geiger Cars keeps much of the carbon fiber that makes the Carbon 65 Edition special and then adds even more of the lightweight material. The body kit includes a new front end with a revised grille for better airflow, fender vents, tweaked side skirts, and Geiger's own rear sub-frame with an integrated diffuser. Buyers also get to pick from three flavors of rear spoilers, ranging from a subtle flat piece to a full racing setup. The firm's changes provide an aggressive appearance but without being overly flamboyant.
To boost the standard Z06 from its stock 650 horsepower (485 kW), Geiger Cars replaces the standard 1.7-liter Eaton supercharger with a 2.3-liter screw-type unit. The company also revises the throttle, intake, and the engine's software. The stock eight-speed automatic or seven-speed manual remain in place. The result is a coupe that can reach 62 miles per hour (100 kilometers per hour) in 2.9 seconds and a max speed of 209 mph (337 kph) – versus 210 mph (338 kph) from Chevy's own ZL1.
Geiger Cars expects people to use these cars at the track, and it makes a variety of upgrades to make sure that fulfill that intention. Modifications for the powertrain cooling systems make the coupe more reliable for lapping a circuit. The firm also fits revised suspension knuckles, which also lower the ride height, and offers more powerful brakes. A set of HRE wheels come with either Michelin Pilot Super Sport or Pilot Sport Cup 2 tires.
The company sells these upgrades a la carte, and the costs grow quickly. The carbon fiber bodykit is 9,600 euros ($11,500 at current exchange rates); the engine upgrade goes for 12,900 euros ($15,400), improved cooling runs 15,500 euros ($18,500); suspension revisions are 4,290 euros ($5,120); HRE wheels sell for 7,400 euros ($8,830); the roll bar costs 2,600 euros ($3,100), and the Schroth racing harness is 1,099 euros ($1,300). In total, these improvements are 53,389 euros ($63,700), and Geiger Cars can sell German customers the Z06 Carbon 65 Edition for 136,000 euros (162,250). Buyers also get a two-day driving course at the Nürburgring Nordschleife.
