For a normal car you typically want to maintain a slight amount of negative camber (0.5 – 1°) to have a good balance of cornering grip, braking grip, and tire wear. On most vehicles it’s common to have slightly more negative camber (0.8 – 1.3°) in the rear to reduce the chances of oversteer (loss of grip in rear).

How do you adjust the negative camber on a BMW?
How do you align camber?
Should camber be 0 degrees?
0 degrees camber gives you the best contact patch and therefore the best performance with heavy braking. Static negative camber will usually cause the inside of the tire to wear more than the outside.
What is acceptable camber?
For normal, modern cars typically feature a slightly negative camber angle is desired (0.5–1° to ensure a good balance and cornering grip, braking grip and tire wear.
What causes negative camber?
If a wheel is perfectly perpendicular to the surface, its camber would be 0 degrees. Camber is described as negative when the top of the tires tilt inward. Consequently, when the top of the tires tilt away from the vehicle it is considered positive. Camber is used to distribute load across the entire tread.
How does negative camber affect handling?
Because negative camber allows the car’s tyre to be kept perpendicular to the road as the vehicle moves along, it will enable drivers to achieve a better grip on the road, reduce wheel vibration, and improve vehicle handling.
Does adding camber lower your car?
Yes, if you move the top mount inboard then you effectively have a longer distance between the knuckle and top mount, if you don’t compensate by lengthening the strut then the car will be lower.
Does camber affect steering?
Positive camber reduces steering effort and provides greater stability in a straight line. This makes it great for off-roading or agricultural vehicles, as turning can sometimes be more difficult in these cases.
Do I need alignment after adjusting camber?
You still won’t need an alignment. Yes you will, you still need to set the camber to ensure it’s even and where you want it. Yes you will, you still need to set the camber to ensure it’s even and where you want it.
Will an alignment fix camber?
Will an Alignment Fix Negative Camber? In some cases, yes. But as mentioned above, camber issues often result from worn or broken parts.
Is it better to have toe in or toe out?
Generally the rule of thumb is that more toe-in increases understeer and more toe-out increases oversteer. However, with modern cars, especially race cars with independent front and rear suspensions, there is another effect on handling.
What camber is best for racing?
A road-racing application also benefits from positive caster between 2 to 5 degrees depending on the car. The camber should generally be 1 to 2 degrees negative.
Does camber cause a pull?
Camber can cause a pull, but it doesn’t do it by being extremely negative or positive, but by being different from side to side. If camber is the cause of your pull, it will always pull to the side with more camber (from negative to positive).
What are good alignment specs?
- Front. Caster: 5.0 degrees. Camber: 1.0 degrees negative.
- Rear. Camber: 1.5 degrees negative. Toe-in: 1/16″, 0.15° or 9 arcminutes total (1/32″, 0.075° or 4.5 minutes per side)
- Front. Caster: 8.0 degrees (basically, as much as possible)
- Rear. Camber: 1.8 degrees negative (matching the front)
How do you tell if your camber is off?
What happens with too much positive camber?
Excessive positive camber causes scuffing or shoulder wear on the outside of the tire. Too much negative camber creates the same wear patterns on the inside of the tire. Basically, anything that affects the tilt of the tire centerline changes camber.
What are the five factors of wheel alignment?
There are five factors involved in setting the alignment to specification: caster, camber, toe, thrust and ride height. Use the following guide to better understand the process and spot potential problems. Caster is the angle of the steering axis (the part of the suspension that supports the wheel and tyre assembly).
Is rear camber good?
Generally, camber plays a key-role in cornering performance. If the camber is out of the manufacturer’s range, it can cause handling issues and excessive tire wear, which costs you money. If a vehicle has rear-camber adjustments, adjusting the rear camber plays a big role in straight-line stability and cornering.
How do I get more positive camber?
Placing shims between the upper control arm shaft and the frame (arrows) will increase negative camber. Adding positive camber involves removing shims. Once you’ve established the camber, caster is the next angle to check. With the bubble gauge installed on the hub, turn the tire inboard 20 degrees and level the gauge.
Is positive or negative caster better?
Performance Benefits of Positive Caster You get better handling when cornering, better stability at high speeds, and better straight-line tracking. The better traction while cornering is similar to a vehicle with negative camber, as it keeps more tread on the ground despite the sharp angles.
Does negative camber improve cornering?
Negative camber is when the wheels are inclined towards the chassis of the car. If you are someone who opts for high-speed cornering, then the negative camber is the ideal camber type for you. The angle allows making high speed cornering a breeze.
Is negative camber good for cornering?
With negative camber, the contact patch can be maximised during cornering, allowing the tyre to lie flush with the road surface which makes for an increase in grip and potential cornering speed.
Do coilovers affect camber?
Coilovers, when installed, will most likely affect the camber of the vehicle. Since the Coilover is a popular way to lower a car, lowering it will give the car a negative camber.
Does camber affect ride quality?
While positive camber is used to improve ride quality and vehicle stability, high performance vehicles may require better cornering performance. Either way, your vehicle manufacturer will have the exact angles for this setting.
