It's interesting to note that GM actually trademarked "High Desert" last month...maybe that package is heading for production?

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
1LE strut tower brace (#23120485)
1LE tires: Goodyear Eagle F1 Supercar G:2 – P285/35ZR20 (#9598378 left / #9598379 right)
1LE wheels: 20 x 10-inch front and 20 x 11-inch rear (#22798741 front / #22798742 rear)
1LE PCV system (#12653073)
ZL1 low-restriction air filter (#92229651)
ZL1 wheel hubs (#25954415)
ZL1 front brake kit (#22959672)
ZL1 rear brake kit (#23104466)
Chevrolet Performance short-throw shifter (#19299460 – suede / #23157703 – leather)
Chevrolet Performance exhaust system (#23206771).

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
Z/28 suspension kit with DSSV® Dampers (#23464729)– a comprehensive suspension package that includes racing-derived spool-valve dampers, higher-rate coil springs, smaller-diameter solid stabilizer bars, and higher-rate suspension bushings
1LE strut tower brace (#23120485)
Z/28 helical differential (#23172755) – a racing-proven, zero-preload limited-slip designed for optimal corning capability and cornering exit traction. It includes the 1LE 3.91-ratio gear set
Z/28 differential cooler (#23216684 – kit with lines) – incorporates an integral heat exchanger, which eliminates the need for an external pump and related hardware
Z/28 aero components kit (#23489551) – includes a front splitter, Gurney lip moldings and a rear spoiler (2014-15 models only)
Z/28 brake ducts kit (#23252398) –channels cool, outside air to the front brakes
Z/28 rear spoiler wicker bill (#23200130) – enhances downforce capability when added to the rear spoiler that’s part of the Z/28 aero components kit
Z/28 air intake (#23454578) – features a conical air filter sealed to the bottom of the hood
Z/28 cat-back exhaust system (#22906768) – offers 26-percent reduced backpressure compared to the SS exhaust and a muscular sound
Z/28 exhaust adapters (#23454579) – to match the exhaust manifolds with the cat-back exhaust system
ZL1 wheel hubs (#25954415)
ZL1 front brake kit (#22959672)
1LE tires: Goodyear Eagle F1 Supercar G:2 – P285/35ZR20 (#9598378 left / #9598379 right)
1LE wheels: 20 x 10-inch front and 20 x 11-inch rear (#22798741 front / #22798742 rear)
1LE PCV system (#12653073)
Chevrolet Performance short-throw shifter (#19299460 – suede / #23157703 – leather).
