The 1LE package is offered on 1SS and 2SS coupe models with an exclusive Tremec TR6060-MM6 six-speed manual transmission. Paired with a numerically higher 3.91 final-drive ratio, the close-ratio gearing of the transmission 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 Chevrolet Camaro 1LE also features exclusive, 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 optimize the 1LE for track-day use include:
- Larger, 27-mm solid front stabilizer bar, and 28-mm solid rear stabilizer bar for improved body control
- Higher-capacity rear-axle half shafts to cope with increased levels of traction
- Strut tower brace for improved steering feel and response
- ZL1-based 20 x 10-inch front and 20 x 10-inch aluminum wheels
- 285/35ZR20 Goodyear Eagle Supercar G:2 tires front and rear (identical to the front tires for ZL1)
- ZL1 wheel bearings, toe links and rear shock mounts for improved on-track performance
- ZL1 high-capacity fuel pump and additional fuel pickups for improved fuel delivery during high-load cornering.
