3792476

This is a special bulletin to introduce the 2014 Chevrolet Camaro Z/28. The purpose of this bulletin is to make you
familiar with the vehicle's features and describe the action your Service Department will need to take to ensure that
your dealership is able to fully service this vehicle. There are special instructions which will need to be followed
during PDI.
More than 190 parts are unique to the Camaro Z/28 when compared to SS models.
The Z/28 is offered in five exterior colors: Red Hot, Black, Silver Ice Metallic, Ashen Gray Metallic and Summit White.
The Standard Z/28 package includes one speaker in the driver’s door. The only single production option available is
a package that adds air conditioning and the six audio speakers that are standard on the Camaro SS.
Accessories available for the Z/28 are:
– SIA – Wicker Bill Spoiler (late availability)
– VYW – floor mats, premium carpet
– RWH – vehicle cover, indoor
– VQL – alternative finish fuel door
Available (not essential) tools for the Z/28 are:
– CH-48897–Brake Rotor Scale - Accurate measurement of the brake rotor mass is required to ensure safe
operation and braking system performance.
– EN-41558-10–Crankshaft Sprocket Remover Bolts
– EN-47812–Installer Bolt – Harmonic Balancer

Powertrain:

3792477

Engine:
The Camaro Z/28 is equipped with a naturally aspirated 7.0-liter V8 engine (LS7), with dry-sump oiling that is rated at
505 horsepower and 481 lb.-ft of torque. The engine is built by hand at the new Performance Build Center within
GM’s Bowling Green Assembly Plant.
Air intake system:
The LS7 uses a unique open air box intake system to make the most of high RPM airflow into the engine. It features
a K&N conical air filter and delivers the highest airflow performance of any production Camaro filter system. The air
cleaner seals around bottom of the hood, reducing the chance of recirculated hot air being drawn into the engine.

Engine Oil and Oil Filter Replacement:
Note: Z/28 utilizes a dry sump oil system. This vehicle will come equipped with factory fill 5W-30 Mobil 1™ oil and
an oil fill cap identifying that 5W-30 Mobil 1™ oil is recommended to top off the engine or for an oil change.
Engine oil capacity 10.0 qt. (9.5 L). The dry-sump system enables high lateral acceleration without a loss in oil
pressure or delivery.
Check the oil level only after the engine has been thoroughly warmed up. After the engine is shutoff, between 5 and
15 minutes, check the oil level. This ensures that the oil level reading obtained will be accurate.
Caution: This engine uses a special high performance oil filter. Use of any other filter may lead to filter failure and/or
severe engine damage. Use oil filter PF64, General Motors P/N 12640445 or equivalent.
To properly change the engine oil and oil filter, refer to Engine Oil and Oil Filter Replacement in SI.

The engine oil is cooled by an integral liquid-to-liquid system, similar to that found on the Corvette ZR1.
Note: Z/28 performance parts have a break-in period. For the first 1,500 miles (2,414 km) avoid full-throttle starts
and abrupt stops, do not exceed 4,000 engine RPM, avoid driving at any one constant speed, and do not drive
above 80 mph (129 km/h). Following these break-in period guidelines will result in better performance in the long run.
Transmission - TREMEC (TR6060) 6-Speed Manual:
A close-ratio six-speed manual transmission is the only transmission offered. The transmission features:
• Close-ratio gearing.
• Combination of double-cone and triple-cone synchronizers on all gears:
• Double-cone synchronizers have two friction surfaces to affect gear acceleration.
• Triple-cone synchronizers have three friction surfaces. The greater the friction surface, the easier the
transmission is to shift.
• Short-throw shifter. The shifter has a more aggressive motion ratio and incorporates a revised shift knob.
The Transmission is cooled by a high-capacity liquid-to-liquid oil cooler system, similar to the Camaro ZL1.
Differential:
The power is distributed to the rear wheels via a Torsen limited-slip differential featuring a helical gear set, rather
than traditional clutch packs, for optimal traction.
Rear Differential Cooler:
The rear differential cooler is the same as Camaro ZL1. It can reduce the temperature by over 100°F (37°C) and
maintains cool, stable performance throughout the most aggressive racetrack sessions.
Note: Regularly scheduled maintenance and fluid changes are STRONGLY recommended. For Z/28 track and
competition driving, replace the axle fluid every 6 hours.

Chassis:
Suspension:
100% of the un-sprung mass (suspension, wheels, tires and brake system) is unique for the Camaro Z-28 when
compared to SS models, dramatically enhancing the balance and overall driving feel of the Z/28.
The front suspension includes double-ball joint multi-link struts, direct-acting 25 mm solid stabilizer bar,
progressive-rate coil springs and inverted monotube shock absorbers.
The rear suspension incorporates a 4.5-link independent design with progressive-rate coil springs over monotube
shock absorbers and a 26 mm solid stabilizer bar.
The Z/28 is one of the first production cars fitted with race-proven, spool-valve dampers (shock absorbers). These
dampers allow four-way damping control, enabling engineers to precisely tune both bump and rebound settings for
high-speed and low-speed wheel motions. The wide tuning range also allows dramatically greater damper stiffness
without a significant change in ride quality.
Additional chassis changes include stiffer spring and bushing rates for improved cornering response.
Performance Track Management (PTM):
Exclusive to GM, PTM is a feature that tailors the performance of Z/28 to match the driver’s skills and driving
conditions. This advanced system integrates steering effort calibrations, traction control, and stability control. Five
PTM performance levels or modes are available:
• Mode 1 – Traction Control set for wet or damp conditions, with stability control on. Steering efforts set to Tour.
• Mode 2 – Intended for entry level drivers - Traction Control set for dry conditions, with stability control on.
Steering set to Tour.
• Mode 3 – Intended for an entry level driver that has become familiar with the track - Traction Control set on
Sport, stability control set to Mode 2. Steering effort set to Sport.
• Mode 4 – Intended for intermediate level drivers familiar with the track - Traction Control set on Sport, stability
control off. Steering efforts set to Sport.
• Mode 5 – Intended for expert level driver familiar with the track - Traction Control set on Race, with stability
control off. Steering efforts set to Track.

Brakes:
Z/28 is equipped with four-wheel disc brakes with ABS, featuring Brembo Carbon Ceramic Matrix™ ventilated
two-piece front and rear rotors. The large 394 x 36 mm front rotors are paired with six-piston calipers. The 390 x 32
mm rear rotors are paired four-piston calipers.
With standard front brake cooling ducts, the Z/28 is capable of continuous track use.
Tip: Due to the floating design of the brake rotor, the front brake rotor cannot be refinished. If the front brake rotor is
found to be at or below the minimum specification, it must be replaced.
Important: The Brembo Carbon Ceramic Matrix™ brake rotors require a very specific break in and burnishing
procedure. Refer to the latest version of PIC5590.
Tires:
The Z/28 is equipped with Pierelli 305/30ZR19 PZero Trofeo R tires and are believed to be the widest front tire on
any production car. The tires are competition oriented tires that are DOT approved for street use. Competition
oriented tires use a special tread pattern and compound that provide more grip than normal road tires. The minimum
tread depth will be reached earlier than typical tires, resulting in reduced tire life.
Warning: Driving on wet roads, in heavy rain, or though standing water with Competition Oriented tires may
cause hydroplaning and loss of control.

This is a race tire. The wear performance of this tire is going to be markedly different than most tires, not just
reduced tire life.
The Z/28 tire package will have significantly reduced tread life.
The special tread pattern and compound will have decreased performance in cold climates, heavy rain, and
standing water.
Competition oriented performance summer tires have rubber compounds that lose flexibility and may develop
surface cracks in the tread area at temperatures below 20° F (-7° C).
Always store Ultra High performance summer tires indoors and at temperatures above 20° F (-7° C) when not
in use.
If the tires have been subjected to 20° F (-7° C) or less, let them warm up in a heated space to at least 50° F
(10° C) for 24 hours or more before being installed or driving a vehicle on which they are installed.
Do not apply heat or blow heated air directly on the tires.
ALWAYS inspect tires before use.
Tires with cosmetic cracking to the tire surface or sidewall will not be covered under the new vehicle tire
warranty.
Only use GM approved tire and wheel combinations. Unapproved combinations may change the vehicle’s
performance and handling characteristics.
The Z/28 uses a specific TPM sensor, it is the same sensor used on the ZL1 and the 1LE. See the electronic
parts catalog for ordering information.
The Z/28 tires cannot be rotated front to rear, they can be moved side to side. If the tires are rotated, the TPM
will need to be reset.
Do not perform wheel alignment for tire wear.

Wheels:

3792482

The Z/28 uses 19-inch forged aluminum wheels. Wheels are staggered:
• 19 x 11 inch aluminum (front)
• 19 x 11.5 inch aluminum (rear).
These wheels have tires mounted to them that contain a special rim protector. The rim protector, built into each tire,
puts rubber over the aluminum of the outer rim for protection when parking.
Steering:
The Z/28 uses electric power steering with variable-ratio, variable-effort rack-and-pinion steering. The steering wheel
turns, lock-to-lock is 2.5.
Alignment:
The Z-28 leaves the factory with the alignment adjusted for street use. These specifications can be found in SI.
Important: Using these alternate wheel alignment settings may result in accelerated tire wear when compared to
other Camaro models. Only use these wheel alignment settings for this vehicle as they are specific for the Z/28 and
optimize the tire and suspension systems. Excessive tire wear is not covered under the vehicle warranty.
The following alignment settings should be used for racing and competitive driving conditions.
Front:
• Caster: 5.9 +/- 0.50 deg.
• Camber: -1.5 +/- 0.5 deg.
• Total or Sum Toe: 0.1 +/- 0.20 deg.
Rear:
• Camber: -1 +/- 0.50 deg.
• Total or Sum Toe: -0.1 +/- 0.20 deg.
• Thrust Angle: 0 +/- 0.20 deg.

Body:
Lighting:
The Z/28 is equipped with halogen headlamps. The High Intensity Discharge, or HID, headlamps and fog lights have
been eliminated.
Front Fascia and Splitter:
The front fascia has a large lower “splitter” to reduce front lift and forces air through the larger lower grille. The larger
openings, splitter and hood extractor all combine for a significant increase in cooling capacity for the powertrain. The
Z/28’s front splitter is a large aero panel that provides downforce at the front of the car, enhancing cornering
capability and high-speed stability. Designed to withstand 250 pounds of downforce at its tip, it is matched with an
aero closeout panel under the front of the engine compartment that also enhances aero characteristics – along with
molded-in aero features forward of the front wheels.

3792485

The Z/28 is equipped with a “Flow Tie” (flow thru Chevrolet bow tie emblem) on the front grille. This design allows for
better air flow and extra cooling.
Rocker moldings and wheel flare moldings:
Specific rocker moldings provide aggressive styling and improved aerodynamic performance, while unique wheel
flare moldings cover the Z/28’s wide tires. Deflectors at the bottom-front corners of the front wheel flares contribute
to the car’s downforce-producing aerodynamics.
Front wheelhouse liners:
Unique wheelhouse liners with closeouts work with the vehicle underbody to make the most of airflow.
Note: The ground clearance of Z/28 is lower compared to the Camaro SS and similar to a Camaro ZL1. Drivers
must use caution when approaching curbs to avoid damage.
Underbody Belly Pan:
The Z/28 underbody incorporates a belly pan that helps reduce front lift.
Tip: The underbody belly pan will need to be removed before performing service work, including oil and filter
changes.
Thinner rear window glass:
Reducing the thickness of the rear window glass from 3.5 mm to 3.2 mm saved 400 grams.
Lightweight rear seat:
Although it looks like the rear seat in the SS, the Z/28’s rear seat is 4.7 kilograms lighter due to reduced seat foam
and a fixed seat back design with no folding/pass-through feature.
Rear Compartment Trim:
The rear compartment interior trim has been deleted on the Z-28.

Interior:
Bluetooth:
The Z/28 is equipped with RPO UPF – Wireless Interface, short range, voice recognition. This option does not allow
you to call a contact when paired to your Bluetooth phone device.
Seats:
The front seats are Recaro seats with microfiber inserts. The seats feature aggressive bolsters for high-performance
driving, and seat cutouts inspired by the five-point harnesses found on racing seats. Both front seats incorporate
manual fore/aft adjustment. Bolster adjustment is not available.
Note: The suede microfiber inserts require unique care when cleaning.
The rear seats of the Z/28 have been modified by eliminating the seat-back pass-through, and uses high density
foam in place of the rigid structure of the seat back and steel mesh of the seat bottom.
Tire- Inflator Kit:
With the exception of Rhode Island and Maryland, where it is required by law, the tire inflator kit has been eliminated
on the Z/28.

Battery:

3792488

The Z/28 uses a smaller, lighter 770 CCA battery.
Steering Wheel:
The flat-bottom steering wheel of Z/28 provides room for heel/toe operation and makes getting in and out of the car
easier. The rim section has also been thickened and tuned to give the driver a more connected feel.
