The bolt pattern is an important set of specifications of the Chevy Camaro that determines wheel compatibility. It is the number and sequence of lug nuts that connect the wheel to the hub with the help of already-installed fasteners. Therefore, its knowledge is imperative for maintenance tasks involving the removal or installation of wheels.
Chevy Camaro has a 5×4.75-inch bolt pattern in the first 4 generations of the car, 1967-2002 models and its facelifts. However, the last 2 generations from 2010-present models have a 5x120mm pattern with slight differences from earlier models.
You will also find details about the torque rating, dimensions of lug nuts, and installation instructions. Furthermore, there will be information about the method to change the bolt pattern of the Camaro.
The bolt pattern of various generations of Chevy Camaro
Chevy Camaro bolt patterns have evolved throughout its generations. The first two generations from 1967-1981 have a simple 5×4.75-inch (5×120.65 mm) setup across all models and engines. It means they have 5 lugs arranged in a circular pattern with a diameter of 120.65 mm of the imaginary circle formed by them.
This consistency continued into the 3rd and 4th generations from 1982-2002 models with the same reliable pattern.
However, the 5th generation from 2010-2015 models saw a slight shift to a 5×120 mm (5×4.72-inch) pattern, remaining the same even through its facelift. 6th generation of the car from 2016-present models also have a 5×120 mm bolt pattern to hold the wheels in their place.
Bolt pattern for various trim levels of Chevy Camaro
The bolt pattern of the Camaro for various trim levels follows the same pattern as for different generations. For the RS, Z28, and SS trim levels from 1967-1969, the bolt pattern is 5×4.75-inch. Moving to the 1970-1981 models, including Base, Rally Sport, LT, RS, SS, and Z28 trim levels, they all share a uniform lug nuts pattern.
The Sport, RS, Berlinetta, and Z28 variants in 1982-1992 models maintain the same bolt pattern as the previous generations. The 4th generation 1993-1997 and 1998-2002 models continue this trend for all trim levels. In the 5th generation, LS and LT trim levels in 2010-2015 models with different engine configurations all adopt a 5x120mm (5×4.72 inches) bolt pattern.
The 2016-present models standardize the bolt pattern across all trim levels, including LS, ZL1, LT, ZL1 LE, 1LS, SS, 1SS 1LT, 1LE, 2LT, 3LT, SS 1LE, and 2SS, and adhere to a 5x120mm arrangement, throughout the Camaro lineup.
Bolt pattern of special editions of Chevy Camaro
Chevy Camaro has multiple special editions within each generation to commemorate special events or as a marketing strategy by the manufacturer. Despite their unique designs and added features, each model follows the bolt pattern of the generation to which it belongs.
For example, the 1968 Z28 Copo Convertible and 1969 Chevy Camaro Yenko have a 5×4.75 bolt pattern. 1985 Camaro IROC-Z has the same bolt pattern as other 3rd generation models. The 2002 Dick Harrell Edition of the Camaro has a 5×4.75-inch (5×120.65 mm) arrangement to hold the wheels.
Other special editions of the car, including the 2017 Copo, 2018 Hot Wheels 50th Anniversary Edition, 2018 SS Redline Edition, and 2020 Camaro GT4.R race car, have 5×120 mm bolt pattern as 6th generation models.
Lug nut dimensions of Chevy Camaro wheels
The lug nuts on Chevy Camaro models feature different thread sizes based on their production years. For the 1967-1981 models, the lug nuts have a thread size of 7/16″ -20, signifying a diameter of 7/16 inches (11.11mm) and a pitch of 20 threads per inch.
From 1982 to 2002, including all trim levels, models with different engine options, and special editions, the thread size transitions to M12x1.5. It indicates a diameter of 12mm and a thread pitch of 1.5 mm, which is the distance between consecutive threads.
The 2010-2015 models utilize lug nuts with an M14x1.5 thread size. Furthermore, 2016-present models also have M14x1.5 dimensions for their lug nuts to fit correctly on the wheel lugs. Besides these dimensions, their head style can also vary, and you need appropriate type sockets to remove or install them.
Torque settings of Chevy Camaro lug nuts
A common method of installing the lug nuts is to keep tightening them until they are snug. Still, the proper way to do this is to use a torque wrench to fix them up to recommended torque settings so that neither they get damaged due to over-torquing nor become loose in harsh operating conditions.
Torque settings of 1967-1981 Camaro models to install lug nuts are 55-80 lb-ft (74.57-108.46 Nm) depending on their quality and material of construction.
However, overstressing can damage fasteners and tapered ends of nuts. I will also recommend avoiding impact wrenches when installing the lug nuts due to the risk of excessive force.
For 1982-2002 models in the 3rd and 4th generations, recommended torque settings are 100 lb-ft (135.58 Nm). Moreover, the torque specifications to install the lug nuts for 2010-2015 and 2016-present models in the 5th and 6th generations are 190 Nm (140.137 ft-lb).
Pattern to tighten the lug nuts of Chevy Camaro
The tightening pattern is another critical aspect of wheel installation to confirm perfect fitment without damaging lug nuts or wheel rims.
A recommended tightening method is the star pattern that requires their installation in a diagonal sequence to ensure even pressure distribution and prevent wheel misalignment.
You will start from any bolt, tighten the next one in its opposite or diagonal location, and so on for other bolts, forming an imaginary star pattern. This criss-cross tightening of bolts promotes stability and reduces the risk of warping brake rotors or damaging the wheel mounting surface.
What other Chevy vehicles have the same bolt pattern as the Camaro?
The 5x120mm and 5×4.75-inch bolt pattern is universal among many Chevy vehicles and other manufacturers. Notable models include the Chevy Corvette 2020-2023 models, Impala 2014-2020 models, Equinox 2010-2017 models, Malibu 2012-2018 models and Omega 1999-2012 models have 5x120mm bolt pattern same as 2010-present Camaro models.
Other vehicles like the Cadillac XT4, XTS, CT5, CT6, and some BMW models also have this bolt pattern. Earlier models of the Chevy Impala, Monte Carlo, Corvette, Blazer, and Caprice have a 5×4.75-inch bolt pattern.
This interchangeability widens the scope for wheel customization and allows for a broader selection of compatible aftermarket options.
Changing bolt pattern of Chevy Camaro
Some enthusiasts or car owners may be required to change the bolt pattern of the Camaro for aesthetic reasons or to accommodate specific wheel designs. However, it involves using adapters fitted on the already installed lugs or modifying the hub.
It’s essential to approach this modification cautiously, as it can impact safety and performance by altering the braking and handling characteristics of the car.
Therefore, you should consult with experienced professionals and consider the potential implications of handling before attempting such changes, as it can also void your warranty because of safety considerations.
