For the front suspension, cars equipped with a MacPherson strut design generally cannot have their camber angle adjusted without installing aftermarket parts. Similarly, many vehicles with a simple non-independent rear suspension, such as a solid or twist-beam axle, also have a fixed camber.
Vehicles with MacPherson struts
The MacPherson strut design combines the coil spring and shock absorber into one unit. The camber angle is primarily determined by the fixed mounting points of the strut and the lower control arm. While this design is simple and cost-effective, it does not allow for factory adjustments to the camber.
Front-wheel-drive cars: MacPherson struts are common on many small and medium front-wheel-drive cars. Aftermarket "camber bolts" or "camber plates" can be installed to add adjustment, but this is not standard.
Issues from modifications: Lowering a car with a MacPherson strut suspension will automatically increase the negative camber. Since this is not adjustable from the factory, it can cause increased inner tire wear and affect handling.
Vehicles with solid or twist-beam axles
On many front-wheel-drive vehicles, the rear suspension uses a solid or twist-beam axle. These simple, non-independent setups have a rigid connection between the two rear wheels, so their camber is not adjustable and cannot be changed independently.
