Not always. A camber kit is only necessary if you cannot bring the wheel camber into the car manufacturer's specification after modifications such as lowering, installing aftermarket suspension parts, or changing wheel sizes. In most cases, stock alignment can be maintained without additional hardware.
What a camber kit does
Camber refers to the tilt of the wheels from vertical. A camber kit expands the range of camber adjustment beyond what the stock suspension provides, allowing you to correct camber wear and optimize grip when ride height or suspension geometry has changed.
How camber kits work
Most kits use either adjustable upper control arms, adjustable bolts at the control arms, or adjustable strut mounts (camber plates) to alter the wheel's tilt. They are designed to restore camber to within manufacturer specs or to achieve a desired negative or positive camber for handling.
When you might need one
Consider a camber kit if your vehicle has changed its camber range due to modifications, and you want to maintain even tire wear and predictable handling. The following scenarios commonly trigger a need for a kit:
- Lowering the vehicle significantly, which can push camber out of spec away from the stock range.
- Installing aftermarket suspension, coilovers, or performance parts that alter suspension geometry and reduce factory camber adjustment.
- Having limited or no camber adjustment left in the stock setup on the front or rear axle.
- Experiencing unusual or uneven tire wear patterns indicating improper camber (e.g., inner or outer edge wear).
- Planning for aggressive driving or track use that benefits from a controlled camber angle.
In practice, many daily drivers that stay close to stock ride height will not need a camber kit, while those with substantial height changes or performance goals often require one to maintain tire life and grip.
Types of camber kits
There are several hardware options, chosen based on the car model, the extent of camber adjustment required, and the budget. Each type offers different ranges of adjustment and installation complexity.
- Camber bolts (eccentric bolts) — inexpensive, simple inserts that shift camber on many older or mainstream models; often used for minor adjustments.
- Adjustable upper control arms — replace the stock upper arm to provide broader camber adjustment and sometimes toe alignment.
- Adjustable lower control arms — extend adjustment options on the opposing arm, useful on some platforms.
- Camber plates — adjustable strut mounts typically used with MacPherson-strut front suspensions to increase camber range at the top of the wheel.
- Full rear camber kits or multi-link rear kits — for vehicles with independent rear suspension or multi-link setups, allowing camber adjustment at the rear to improve wear and handling.
Choosing the right kit requires checking your vehicle's serviceable adjustment range and consulting with a shop or the manufacturer’s specs to avoid overcorrection or alignment instability.
Installation considerations and safety
Camber kit installation should be followed by a professional alignment to ensure toe and caster are set within spec. Improper installation or over-adjustment can lead to uneven tire wear, reduced steering feel, or handling instability. Always use hardware recommended for your vehicle and obey the torque specs in the service manual.
Summary
Bottom line: you usually do not need a camber kit for a standard, unmodified vehicle. If you lower your car, install suspension that changes geometry, or encounter tire wear due to excessive or insufficient camber, a camber kit can restore proper camber and improve grip and tire life. The best choice depends on your car, how much camber adjustment you need, and your budget; consult a qualified technician to determine the right solution for your setup.
