What camber is best for drag racing?

Camber should be set at zero; you should try to keep the front wheels straight up and down. Toe-in should be as close to zero as possible on a production line chassis. On a strut-equipped tube-frame car, Bickel recommends 3/16-inch of toe.

What camber do race cars use?

In a NASCAR ^® oval race, the race cars only make left turns. This means the right wheels are always on the outside of a turn, so NASCAR ^® mechanics use negative camber on them. The left hand wheels are on the inside of the turn, so they use positive camber.

Is positive camber good for racing?

For the left wheels, they use positive camber, because those wheels will always be on the inside of a turn. With this ideal cornering combination, NASCAR race cars can have optimal grip and stability during a turn and thus maximum corning speeds.

Why is negative camber good for racing?

Simply put, negative camber helps counteract the natural tendency for a tire to roll onto its outer shoulder while cornering, keeping the contact patch squarely on the road while cornering allow for more grip and higher cornering speeds.

What's better negative or positive camber?

Positive Camber - When your wheels are tilted outward, the vehicle has improved stability. Negative Camber - High performance vehicles that require better cornering tend to use negative camber, because it gives the driver more control in this regard.

Drag Car Front End Alignment

What camber do F1 cars run?

This is the angle of the wheel and tyre assembly relative to the vertical and, at a standstill, the front camber angle is usually around 3.5 degrees from vertical with the rear set at between zero and one degree.

Is rear negative camber good?

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.

What is the best camber angle?

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 is too much negative camber?

Excessive negative camber can cause the wheels to tramline, or follow cracks in the road. It also worsens acceleration and braking in a straight line. The vehicle is often too sensitive to the crown of the road (curvature designed for water drainage to the sides of the road).

How much camber do race cars run?

Front -2 to -2.5 degrees, toe 1/16" in (+. 25 deg) & Rear 0 to -0.5 degrees, toe 0. Excessive toe is what causes uneven tread wear, not camber.

What is better 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.

Is camber good for drag?

Most production line cars require different camber figures (while at rest) so that good grip and tire wear is maintained as the car travels down the road. Typically, a car with a small amount of negative camber will exhibit better drag strip handling characteristics without killing the tire.

How much camber should a drag car have?

The camber should generally be 1 to 2 degrees negative. Toe should usually be set at zero, but sometimes the tires will be toed out slightly to help the car with turn-in, but this is more of a driver's preference issue.

Should camber be 0 degrees?

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.

How much negative camber is OK?

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).

What is 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.

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.

Will negative camber cause a pull?

Excessive negative camber will cause scuffing of the inside edge of the tire. Camber can cause pull if it unequal side-to-side. The vehicle will pull toward the side with the most positive camber. A difference of more than half of a degree from one side to the other will cause vehicle to pull.

Does camber affect ride quality?

Camber is used to distribute load across the entire tread. Improper camber can make the tire wear on one edge and may cause the vehicle to pull to the side that has the most positive camber. Zero camber will result in the most uniform tire wear over time, but may reduce performance during cornering.

Why do F1 cars toe out?

This means that the front wheels are splayed outwards, whereas the rear will be pointing inwards. Front toe out not only helps to put heat into the tyre as there is a slight scrubbing effect, but can help give more grip and stability when the wheels are turned.

How does toe affect a race car?

Toe In. Running toe in will also decrease the acceleration and top speed of the car in a straight line. This is due to the front wheels not being driven so any extra grip generated by toe will increase the drag on the system. The life of the tyre is also reduced due to the increased stresses on the rubber.

Does camber affect speed?

Traction for braking and acceleration will decrease due to the smaller contact patch while the wheels are straight. Cars with negative camber will also tend to tramline and wander by following cambers and grooves in the road surface, which reduces high speed stability.
