Adjust Camber on Your Car's Wheels Guide

Understanding Camber and Why It Matters

Camber is the angle of your car's wheels relative to a vertical line when viewed from the front or rear of the vehicle. If your wheels lean inward at the top, that's negative camber. If they lean outward at the top, that's positive camber. Zero camber means the wheels are perfectly vertical. This measurement matters because it directly affects how your tires wear, how your car handles corners, and how much control you have while braking.

When camber angles are incorrect, your tires wear unevenly and faster than they should. A tire with too much negative camber might wear heavily on the inside edge, while a tire with too much positive camber wears on the outside edge. This uneven wear can reduce tire lifespan by thousands of miles. Beyond tire wear, incorrect camber affects steering response and stability. Many drivers notice their car pulling to one side, or the steering wheel not returning to center smoothly after turning, as signs of camber misalignment.

Most modern cars come from the factory with a slight amount of negative camber, typically between 0 and -1.5 degrees, depending on the vehicle model. This factory setting balances tire life, handling, and stability for average driving conditions. Performance vehicles and sports cars often have more negative camber to improve cornering grip. Understanding this baseline for your vehicle helps you determine whether adjusting camber will benefit your specific driving style and needs.

Camber adjustment becomes important when you modify your vehicle's suspension—such as lowering springs or coilovers—because these changes alter the wheel's angle. Similarly, after an accident or hitting a pothole, camber angles can shift. Learning to measure and adjust camber yourself can save you money compared to repeated professional alignment visits.

Practical Takeaway: Check your vehicle's owner's manual or manufacturer specifications to find the factory camber range for your specific make, model, and year. This number becomes your target when adjusting camber yourself.

Tools and Equipment You'll Need

Adjusting camber at home requires specific tools that help you measure angles accurately and safely access the suspension components. The most essential tool is a camber gauge, sometimes called a camber meter or alignment tool. Modern camber gauges attach to your wheel rim and provide a digital or analog reading of the wheel's angle. Digital gauges typically cost between $30 and $150, while mechanical gauges run $20 to $60. Some DIYers use a bubble level combined with a homemade frame, though purchased gauges offer better accuracy.

Beyond the camber gauge, you need a vehicle lift system. This could be a hydraulic floor jack rated for your vehicle's weight, jack stands (absolutely essential for safety), or a proper 4-post lift if available at a garage. Never work under a car supported only by a jack—always use redundant support. A torque wrench is necessary for re-tightening suspension components to manufacturer specifications after adjustment, typically ranging from 30 to 80 foot-pounds depending on the bolt. Impact tools should be avoided for these fasteners as they can overtighten.

Additional tools include a basic socket set, wrenches (both metric and standard, depending on your vehicle), a wheel alignment board or caster/camber plates (optional but useful for front-wheel-drive vehicles), an angle finder app for smartphones, and a straight edge. Many suspension components have castle nuts or cotter pins that require specific removal, so keep a small variety of pliers and cutting tools on hand. Some vehicles have slotted mounting holes that allow camber adjustment with simple bolt movement, while others require specialized adjustable suspension arms or eccentric bolts.

Safety equipment matters significantly. Wear mechanic's gloves, safety glasses, and a work light so you can see suspension components clearly. A creeper or low stool helps you position yourself under the vehicle comfortably. Have a friend nearby who can assist if needed—suspension work goes faster and safer with a second set of hands.

Practical Takeaway: Before purchasing tools, research your specific vehicle model to determine whether your camber adjustment points use slotted holes, eccentric bolts, or require adjustable control arms. This determines which tools you actually need.

Measuring Camber Accurately

Measuring camber begins with preparing your vehicle properly. Park on a level surface—preferably a garage floor or flat driveway—and turn off the engine. The vehicle must be at ride height with the suspension in its normal position. Do not measure camber with the car lifted, as suspension geometry changes when weight is removed. Some measurements are taken with the wheels at 20 degrees of steering angle (the "20-degree method"), which accounts for how the suspension moves during turns, but for basic adjustment work, straight-ahead measurement is typical.

Attach your camber gauge to the wheel rim following the manufacturer's instructions. Most gauges mount to the center cap area and read the angle against gravity. Take measurements at multiple points around the wheel rim—typically top, bottom, left, and right—then average those readings for accuracy. Repeat measurements two or three times to confirm consistency. Small variations between readings are normal and represent measurement tolerance. Record your measurements clearly: note which wheel (front-left, front-right, rear-left, rear-right), the angle reading, and the date.

After recording initial measurements, compare them to your vehicle's factory specifications found in the owner's manual, service manual, or manufacturer website. Write down the target camber range for each wheel position. For example, a common specification for front wheels might be -0.5 degrees to -1.5 degrees, with a preferred setting of -1.0 degree. Rear wheels often have different specifications, sometimes even positive camber. The difference between your current measurement and the target tells you which direction to adjust.

Before making any adjustments, take photographs of your suspension's current state. Document bolt positions, any witness marks (marks showing parts' relative position), and the overall configuration. This visual record helps you remember what was where if anything goes wrong, and it's invaluable if you need to return components to original positions. Some technicians use paint to mark reference points on adjustable bolts and mounting holes to track rotation.

Practical Takeaway: Write measurements on a piece of paper and keep it with you during the adjustment process. Having the target numbers visible prevents mistakes and keeps the job organized.

Adjustment Methods for Different Suspension Types

Different vehicles use different camber adjustment mechanisms, and understanding your vehicle's system is crucial. The most common front-suspension adjustment method uses eccentric bolts (also called cam bolts) at the strut's lower mounting point. These bolts have an offset center hole, so rotating the bolt changes the strut's angle. To adjust, loosen the bolt slightly—not completely—then rotate it in the direction needed to achieve your target camber. A small rotation creates significant angle change, so work gradually. After each adjustment, tighten the bolt to the manufacturer's specification torque and remeasure.

Some vehicles, particularly older models and certain Hondas, use slotted mounting holes. The strut or control arm mounts through a slot rather than a round hole, allowing horizontal movement. Loosen the mounting bolts enough to move the component, then slide it slightly inward or outward to adjust camber. This method is more intuitive but requires careful measurement to achieve precise angles. Mark your starting position with a marker before loosening, so you can move in accurate increments.

Adjustable control arms offer another camber adjustment option. Some aftermarket kits replace the factory upper control arm with an adjustable version that can lengthen or shorten. This changes the angle at which the arm connects the steering knuckle to the frame. Turning the adjustment bolt extends or retracts the arm, altering camber. These kits require careful measurement, as small movements create large angle changes. Always adjust in small increments and remeasure between adjustments.

For rear-wheel camber, adjustment methods vary widely. Some vehicles have adjustable trailing arms, others have cam bolts similar to front suspensions, and some older cars have shim kits that add material behind mounting points to change angles. Always consult your vehicle's service manual to identify your specific adjustment mechanism. If your vehicle uses shims, adjustment becomes more involved—you may need to remove the component, add or remove shim material, and reinstall. This typically requires professional equipment or help from a shop.
