CHOICE OF POWERFLO® OR LOUD MOUTH II® EXHAUST SYSTEMS
Both of SLP’s axle-back exhaust systems were designed and tuned specifically for our new Supercharged ZL427 and ZL454 Camaros. The PowerFlo System is louder than stock and features a deep, rich and powerful sound. For a louder exhaust tone, we offer the Loud Mouth II System providing a perfect blend of Muscle Car and Grand Touring sound quality. Both systems include black power-coated tips that slip into the openings of our new Rear Diffuser.
25% UNDERDRIVE PULLEY/HARMONIC BALANCER
SLP’s unique Underdrive Pulley/Harmonic Balancer for the ZL427and ZL454 Camaros reduces engine accessory (water pump, alternator and A/C compressor) drive speed by 25%, contributing to the engine’s increased horsepower output. It features steel construction and incorporates a pair of extra-tall belt retention walls that eliminate any possibility of belt slippage.
BLACKWING® COLD-AIR INDUCTION SYSTEM
SLP pioneered this power-enhancing technology many years ago on the fourth generation F-car-based Camaro. This technology is now incorporated in our new 2011 V8 ZL Camaros. The Blackwing Cold-Air Induction System replaces the restrictive, power robbing factory air filter and intake tube assembly providing a noticeable power gain. The system includes an OEM-quality black-finished polypropylene high-flow intake tube with a raised SLP Blackwing logo and a high-flow, reusable Blackwing filter.
ZL SHORT-THROW SHIFTER W/LEATHER SHIFT KNOB
SLP’s short-throw shifter assembly for the manual transmission Supercharged Camaro ZL454 provides a 20% reduction in shift lever throw and a more positive feel while shifting gears. The shifter mechanism is machined from one solid piece of billet 303 stainless steel. New K-Prene bushings are included. The ergonomic shift knob is leather wrapped, features a silver stitched ZL logo and feels great in your hand!
CUSTOM-TUNED PCM PROGRAM
Every one of SLP’s ZL427/454 Camaro Specialty Vehicles includes a non-adjustable, Performance-Optimized PCM Custom Tune which is pre-installed using our hand-held programmer (included). All of SLP’s Custom tunes are dynamometer-developed to provide maximum horsepower and torque increases, while maintaining the Camaro’s excellent driveability.
OPTIONAL COIL-OVER SPRING/SHOCK PACKAGE
SLP’s High Performance Coil-Over Spring and Shock Package for the 5th Gen. Camaro was developed and tuned specifically by SLP and Eibach. This system will provide the next level of Suspension Technology for customers looking for a more performance-oriented suspension upgrade than our Sport Suspension Spring Package. This exciting new suspension package allows serious performance enthusiasts the ability to quickly adjust the ride-height (0-2″) and corner-weight of each individual wheel, giving you the flexibility for precise street and track tuning. Requires SLP’s Adjustable Sway Bar Package.
OPTIONAL SPORT SUSPENSION PACKAGE
SLP’s optional Sport Suspension Spring Package is specifically engineered and tuned for the new V8 ZL Camaros. By lowering the chassis 1.0″ in the front and rear, it gives the 2011 ZL427/454 Camaros a more aggressive stance, lower center of gravity and delivers even more response and control during high speed cornering. These German engineered, progressive rate springs are made to the same rigorous performance and quality standards as the springs used for NASCAR, Formula 1, Indy Car and the World Rally Championship.

OPTIONAL WHEEL AND TIRE PACKAGE
For optimal grip and improved acceleration, handling and braking, SLP’s Optional Wheel and Tire Package is the answer. Package includes a set of two 9″ wide front and two 10″ wide rear 20″ Five Spoke ZL Red Line Wheels, Tire Pressure Monitoring Sensors and a set of mounted and balanced high-performance Michelin PS2 Tires (255/40ZR20 front and 295/35ZR20 rear) – the same high-performance tires used by Ferrari, Bugatti and on the Corvette ZR1.
OPTIONAL ADJUSTABLE SWAY BAR PACKAGE
SLP’s optional, Performance Front and Rear Sway Bar Package with adjustable links provides an easy-to-install, cost-effective upgrade that will significantly improve traction and the overall handling characteristics of the ZL427 and ZL454 Camaros. These tubular bars are both 29mm in diameter compared to the 23mm solid front and rear factory bars. The front bar has two positions of adjustability, while the rear bar has three adjustments. When combined with our optional Sport Suspension Spring Package, this Sway Bar Package provides world class handling.
All of SLP’s exterior styling features help reinforce the SuperCar image of our 2011 ZL Camaros. From the new, functional front splitter and rear diffuser to the aggressive rear spoiler and uniquely styled 20″ wheels, this car makes a powerful performance statement, ensuring its place with the new generation of Camaro Classics.
FRONT SPLITTER

Our new front splitter adds to the already aggressive front end look of the ZL Camaro. It also increases front end down force and stability at high speeds.
All of SLP’s exterior styling features help reinforce the SuperCar image of our ZL427/454 2011 Camaros. From the functional hood scoop, to the aggressive rear spoiler and uniquely styled 20” wheels, this car makes a powerful performance statement, ensuring its place with the new generation of Camaro classics.
FUNCTIONAL REAR SPOILER

SLP’s OE-quality composite Rear Spoiler is a taller, more aggressive design, while still maintaining many of the design features of the stock spoiler. It provides increased down-force at higher speeds to improve vehicle stability. (Design patent pending)
OPTIONAL PERFORMANCE HOOD WITH FUNCTIONAL SCOOP

SLP’s optional RTM Hood with Functional Heat Extractor Scoop (design patent pending) provides a more aggressive performance image. It features OE-quality RTM composite material, is the same weight as the stock hood and includes many of the factory hood design features including crush initiators and attaching hardware. The functional scoop allows cold, fresh air to enter the engine compartment, forcing hot, under-hood air out. It includes an injection molded grille for the hood scoop opening and an injection molded
close-out panel insert for the non-functional opening in the front fascia (SS models only).
REAR 1/4 PANEL GILL INSERTS

These gill insert graphics fade from clear to solid gloss black, giving the ZL Camaro’s rear 1/4 panels the appearance of functional vents. Similar to the early Camaro gill accents, they also were part of the early Camaro’s heritage.
20″ FIVE SPOKE RED LINE WHEELS

SLP’s OE-quality aluminum alloy wheels feature a powder-coated red line at the outer edge of the rim, reminiscent of the early Camaro’s Red Line tires. These light-weight 20” x 8” front and 20” x 9” rear wheels provide the same offset and width as the factory wheels. The wheels are painted metallic gray with a machined spoke face and include ZL center caps. (Wheel design patent pending).
OPTIONAL PAINTED RALLY STRIPES* OR HOCKEY STICK STRIPES

SLP’s ZL® Camaros can be ordered with either one of these traditional muscle car stripe themes. The Rally Stripes are painted on and clear-coated, using the same paint and clear finish that the factory supplies, providing a lasting finish that won’t fade. The Hockey Stick Stripes are OE-quality vinyl graphics.
Both optional stripe themes are available in Black, White, Silver and Hugger Orange, all with a non-metallic, high-gloss finish. Any of the available stripe colors can be ordered in combination with any factory Camaro exterior color.
*Rally Stripes are only available with SLP’s optional Performance Hood.
