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 is the importance of toe out on turns?

The angle of the steering arm on the steering knuckle determines the turning radius. It’s known as the Toe Out On Turns or the TOOT angle. This angle keeps the front tires from squealing around corners.

How does toe affect steering?

Toe can also be used to alter a vehicle’s handling traits. Increased toe-in will typically result in reduced oversteer, help steady the car and enhance high-speed stability. Increased toe-out will typically result in reduced understeer, helping free up the car, especially during initial turn-in while entering a corner.

What are good alignment specs?

Recommended alignment numbers

• 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)

What is the purpose of toe in?

A toe in alignment of the wheels can help to reduce over steer problems and can increase stability in vehicles that have front-wheel drives. Alternately, a toe out alignment can help to mitigate issues related to under steering and can improve the handling on a vehicle that has a rear-wheel drive.

What is positive toe on a car?

Negative toe, or toe out, is the front of the wheel pointing away from the centreline of the vehicle. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle.

Is too much toe in bad?

Excessive toe-in or toe-out causes the tires to scrub, since they are always turned relative to the direction of travel. Too much toe-in causes accelerated wear at the outboard edges of the tires, while too much toe-out causes wear at the inboard edges.

Does toe in increase stability?

Toe In. On the front of the car, toe in increases straight line stability. This is because if one of the wheels is disturbed during straight line driving and is pulled rearward of the steering axis then the wheel will steer outwards.

Is toe in good for drifting?

You shouldn’t run too much rear toe-in on a drift car. By doing so, you’ll have a car that will straighten up if the throttle is lifted or modulated. This is the leading cause of serious drift car crashes. A car’s understeer/oversteer balance should always be adjusted in the suspension, not by using the toe.

How does toe angle affect handling?

The toe angle affects directional control, turning response and tire tread life. Commonly, a rear-drive vehicle would likely require a front wheel toe-in (positive) setting, and a front-wheel-drive vehicle would likely require a slight toe-out (negative) setting.

What is positive toe?

Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle.

Is toe in good?

Toe is the point of the front tires when a vehicle is viewed from above. Camber affects tire wear and the handling of the car. Most vehicles have a slight negative camber, but in some cases, a positive camber is more suitable.

How important is toe on steering wheel?

If you are truly concerned about it, zero toe is also acceptable and recommended for a “sportier” feeling steering while maintaining some stability at speed. A slight bit of toe in can help stabilize the car at speed if you do a lot of highway driving and wouldn’t hurt.

What is the difference between toe-in and toe-out?

All racers know the difference between toe-in and toe-out (alignment). However, the many forms of toe-out can be confusing or misunderstood. Toe-out can be found in at least one of five main forms; static toe out, toe out on turns “ackerman steering”, toe out due to bump steer, steering arm toe out, and toe out due to slip angles.

What are the advantages and disadvantages of toe-out in racing?

These various forms have advantages and disadvantages. One objective in using toe-out with a race car is to increase the turning force generated at the front of the car. So, if your race car understeers (pushes) in the middle of a turn, then a little toe-out may help reduce or cure your problem.

Why do my Wheels toe out when I turn?

This causes the wheels to toe-out when the steering wheel is turned. This is why some alignment shops and dealerships refer to Ackerman as toe-out on turns (not to be confused with static toe-out). Toe-out can also be the result of bump steer. The toe-out in this situation occurs during ride motions or body roll.
