A Small Wheel Angle Can Make a Big Difference
Have you ever looked at an RC car from the front and noticed that its wheels lean slightly inward? That tilt may be intentional and it is called camber.
RC enthusiasts often focus on motors, batteries and speed upgrades, but suspension setup also deserves attention. Understanding wheel alignment helps you tune how your car behaves through corners and recognise when something needs repair.
Whether you enjoy racing, drifting, off-road driving or simply learning about your RC model, camber is a useful place to start.
What Is Camber in an RC Car?
Camber is the inward or outward tilt of a wheel relative to vertical, viewed from the front or rear of the car. It is measured in degrees.
There are three basic types:
Camber TypeWheel PositionMeaningNegative camberTop leans toward the chassisThe wheel tilts inwardZero camberWheel stands verticallyNo inward or outward tiltPositive camberTop leans away from the chassisThe wheel tilts outward
These definitions describe the wheel’s tilt, not the direction it points when steering. Traxxas uses the same distinction in its suspension tuning guidance. traxxas.com
1. Negative Camber: Why Do RC Wheels Lean Inward?
Negative camber is commonly used in RC racing.
When a car corners, its chassis rolls and the outside tyres carry more of the load. Suitable negative camber can help those tyres maintain better contact with the surface through the turn.
However, more negative camber does not automatically mean more grip. Too much can hurt handling, and mismatched left and right settings can make the car behave differently in opposite turns. traxxas.com
For beginners, the important lesson is to start with the manufacturer’s setup and make small changes based on testing.
Does Negative Camber Make the Car Faster?
It does not increase motor power or gearing speed. Its purpose is to tune tyre contact and handling.
A suitable setup may help you carry speed through a corner more confidently, but an unsuitable one can make the car harder to drive.
2. Zero Camber: Wheels Standing Straight
At zero camber, the wheel stands vertically when the car rests on a level surface.
This gives you an easy reference when checking alignment. However, a wheel that stands straight while stationary may change angle as the suspension moves.
Static camber is measured with the car resting at its normal ride height. The wheel angle during suspension movement can differ, depending on the chassis geometry.
3. Positive Camber: Wheels Leaning Outward
Positive camber means the top of the wheel leans away from the chassis.
Do not assume that visible outward lean is an intended performance setting. Compare it with the model’s manual, especially if it appeared after a crash.
A bent suspension part, loose mounting point or damaged hub can change wheel alignment. Fixing that fault should come before tuning.
Camber, Toe and Caster: What Is the Difference?
These terms describe different aspects of suspension geometry.

Camber and toe are separate settings. Adjusting a steering link when you intended to change camber can alter the wrong part of your setup. Traxxas distinguishes camber from toe in its tuning guide. traxxas.com
Can Every RC Car or Toy Have Its Camber Adjusted?
No. Adjustability depends on the suspension design.
Hobby-Grade RC Cars
Some hobby-grade cars use adjustable upper links or turnbuckles. Others use pivot balls, shims or model-specific parts.
Check the manual before turning anything. An adjustable-looking link may control steering rather than camber.
Toy-Grade RC Cars
Many basic RC toys use fixed suspension links or moulded assemblies. They may not provide a camber adjustment.
If the wheels look uneven, inspect for damage or loose parts. Avoid bending fixed components to create a different angle.
Solid-Axle RC Crawlers
Many scale crawlers use solid axles. Their suspension links position the axle rather than providing the same individual wheel camber adjustment found on independent-suspension cars.
A touring-car tuning method therefore may not apply to your crawler.
What Is the Best Camber Angle for an RC Car?
There is no single angle that works for every model.
The suitable setting depends on tyre construction, surface grip, suspension geometry, ride height and driving style. Front and rear settings may also differ.
For example, one Traxxas alignment guide specifies 2° of negative camber for the setup it describes. That is a model-specific instruction, not a universal setting for all RC cars. traxxas.com

How to Check and Adjust RC Camber
Step 1: Inspect the Car
Check wheel bearings, suspension arms, links, hubs and mounting screws. Excessive play makes accurate measurement difficult.
Step 2: Prepare a Level Surface
Place the car on a flat setup board or table. Fit the battery and normal running equipment so the suspension carries its usual weight.
Step 3: Settle the Suspension
Gently compress and release the suspension, then roll the car slightly forward and backward. Measure at normal ride height, with the steering centred.
Step 4: Measure the Angle
Use a suitable RC camber gauge. Follow its instructions and measure consistently on both sides.
Avoid judging small differences from photographs—the camera angle can be misleading.
Step 5: Make a Small Adjustment
Follow the model’s manual and use the correct tool. Keep adequate thread engagement in adjustable links, and check that the suspension moves freely afterward.
Step 6: Recheck and Test
Measure again, check steering clearance and recheck toe if needed. Test on the same surface while keeping other settings unchanged.
Record the original setting so you can return to it.
Common Camber Mistakes
- Copying another car’s setup: Different chassis and tyres can need different settings.
- Choosing an extreme angle for appearance: A dramatic stance does not prove better performance.
- Measuring with the car lifted: Fully extended suspension does not represent normal ride height.
- Changing several settings together: This makes it difficult to identify what helped.
- Ignoring unequal wheel angles: First check for damage, loose parts or uneven suspension.
- Treating tyre wear as proof of one fault: Toe, tyre condition and driving surface also deserve inspection.
What If Your RC Car Pulls to One Side?
Camber is only one item to check.
Inspect steering trim, toe alignment, tyre condition, wheel bearings, suspension damage and drivetrain resistance before changing the setup.
If the problem started immediately after an impact, focus on finding the damaged or displaced part first.
Get to Know Your RC Car Beyond Speed
Learning about camber turns suspension tuning into a practical experiment: measure, change one setting, drive and compare.
Begin with your model’s recommended setup. Aim for predictable handling and consistent results, then make adjustments as your understanding grows.
