Times are around Spring Mountain.
Stage 1 – Stock Camaro SS
Best Lap Time: 2:05.10
Serving as the control group for the concept cars, these cars demonstrated the performance of factory-stock Camaro SS models, which include fully independent front and rear suspensions – with the rear suspension featuring a 4.5-link system that includes a unique, L-shaped upper control arm that attaches to the knuckle at one end and incorporates a ride bushing in the rear. The front suspension has a dual-ball strut system, with a direct-acting stabilizer bar.
Four-wheel disc brakes with Brembo four-piston calipers are standard, while an electric power steering system originally developed for the ZL1 has been standard on the SS since 2013. All Stage 1 cars ran the course on stock wheels and tires:
20 x 8-inch aluminum wheels and P245/45ZR20 tires in the front
20 x 9-inch aluminum wheels and P275/40ZR20 tires in the rear.
Stage 2 – Ultimate Street Camaro SS
Best Lap Time: 1:59.30
The 1LE package is offered on regular-production SS coupe models and features an exclusive package of transmission, chassis and suspension components tuned for enhanced performance. Many of the parts – as well as key parts from the supercharged Camaro ZL1 – are available as direct bolt-on enhancements to shave about 6 seconds off the stock Camaro SS’s lap time.
The components used to build the Camaro SS Ultimate Street Car include:
1LE sport suspension package (#23123397) – includes a larger, 27mm solid front stabilizer bar and 28mm solid rear stabilizer bar for improved body control; and revised toe links and rear shock mounts for improved on-track performance

Stage 3 –Ultimate Track Camaro SS
Best Lap Time: 1:56.43
Leveraging key components of the Camaro Z/28 – recipient of Motor Trend’s 2014 Best Driver’s Car award – the Ultimate Track Camaro SS concepts demonstrated the ultimate in track capability for SS models.
Along with the additional power supplied by its enhanced LS3 6.2L engine – featuring a camshaft kit and CNC-ported cylinder heads available from Chevrolet Performance – the Ultimate Track Camaro SS was 2.9 seconds faster than the Ultimate Street Camaro SS, and 8.7 seconds faster than the stock Camaro SS.
“With the Z/28 parts, the Camaro SS is transformed into an entirely track-focused machine,” said ****ens. “The steering is responsive and precise, allowing you to carve down to the apex with ease – and it confidently gets the power to the ground while exiting turns. Perhaps even more amazing is that the on-track transformation is accessible with parts that literally bolt on to any 2010-and-newer Camaro SS.”
The parts roster for the Ultimate Track Camaro SS includes:
LS3 Power Upgrade Kit (#19301990) – includes camshaft and cylinder heads, enabling 30-horsepower gain over the engine’s stock output
