Chevrolet Performance recently released news that they now offer a collection of factory-engineered performance parts and accessories for 2010 and newer Camaros. Making it even more convenient is that many of them preserve the vehicle warranty as long as they are installed by a Chevrolet dealer.

Camaro ZL1 RearBrake ConversionKit 2/4

Components from the Camaro ZL1 and SS 1LE are included in the assortment of parts, which are designed to make fifth-generation Camaro V-6 and SS cars more capable on the street as well as the track.

Chevrolet Performance is also offering the ZL1 rear driveline system which is the strongest independent rear axle option available for the Camaro. It features a 9.9-inch rear differential in a cast iron center section along with other high-strength components. Suspension components from the 1LE are useful for those demanding neutral handling for your favorite twisty road, highway off-ramp, or the track.

"Chevrolet Performance is the first stop for owners building a competitive, durable Camaro for the track," said Jim Campbell, GM U.S. vice president of performance vehicles and motorsports. "These Chevrolet Performance parts are based on Chevrolet factory-validated production components that were tested on racetracks and validated to standards unmatched in the aftermarket industry. Quite simply, they're tailored for improved performance and built to the highest standards."

Different torsional stiffness rates work in conjunction with the limited-slip differential to minimize wheelhop at launch. While a direct bolt-in, additional parts may be required for installation (manual 3.73 axle ratio and automatic 3.23 axle ratio).

Camaro 1LE components:

- 1LE strut tower brace (part #22756880) - Greater stiffness to the front body structure enhances turn-in feel and supports more direct feeling steering inputs made possible by the 2011 and later bolt-on strut tower brace for both V-6 and SS models.

- 1LE PCV valve (part #12653073) - Oil separation and drain-back are ensured during high-load cornering with this PCV valve.

Camaro SS components:

- SS brake kit for Camaro V-6 (part # 23120542) - Brembo front and rear brake components equivalent to those off of the SS make for an economical option for customers who want greater brake performance but don't require the performance of ZL1 brakes.

The high-lift LS7 camshaft makes the most of the heads' airflow capabilities, with 0.558/0.558-inch lift and 211/230 degrees of duration at 0.050-inch and a 121-degree lobe separation angle. Camshaft and fully-assembled cylinder heads are included, while head gaskets and cylinder head bolts must be purchased separately, and tuning is required. This kit fits other LS-family engines with at least 4.000-inch bores.

COPO components for the drag strip

Along with ZL1, 1LE, and SS components, Chevrolet Performance also offers quite a few COPO Camaro parts, which allow racers to build a Camaro race car to their own specifications, including the COPO Camaro hood (part #22950678) and COPO-logo gauges.
