The Chevrolet Camaro 1LE performance package returns for 2013 with unique gearing, suspension tuning and tyres. The 1LE package gives the Chevy more than 1g of lateral acceleration and a sub-three minute lap time at Virginia International Raceway’s Grand Course. It is offered on Camaro SS coupes with manual transmissions.

The 1LE package is offered on 1SS and 2SS coupe models with an exclusive Tremec TR6060-MM6 six-speed stick shift. Paired with a numerically higher 3.91 final-drive ratio, the close-ratio gearing of the gearbox is tuned for “road-racing performance”. As with the ZL1, the 1LE transmission features a standard air-to-liquid cooling system for track use.

The Camaro 1LE also features monotube rear dampers instead of the twin-tube dampers on SS models. The new hardware allowed engineers to tune the 1LE suspension to focus on optimal body-motion control while preserving much of the ride quality and wheel-motion control of the Camaro SS.

Other changes to optimise the 1LE for track use include larger solid stabiliser bars at both ends, higher-capacity rear-axle half shafts, strut tower brace for improved steering feel and response, ZL1-based 20 x 10-inch wheels with 285/35 ZR20 Goodyear Eagle Supercar G:2 tyres, ZL1 wheel bearings, toe links and rear shock mounts and a ZL1 high-capacity fuel pump and additional fuel pickups.

Visually, the 1LE package is distinguished by its matte black hood, front splitter and rear spoiler – as well as the 10-spoke ZL1-based wheels, which are finished in black. The functional front splitter and rear spoiler contribute to the car’s track performance by helping to reduce aerodynamic lift at high speeds.

Inside, the package incorporates the ZL1’s flat-bottom steering wheel, trimmed in sueded-microfibre. The quick-acting, short-throw shifter from the ZL1 is also trimmed in the same material.
