Forza Horizon 4 Beginner's Tuning Guide

The difference between a good car and a great car in Forza Horizon 4 is in the tuning. In order to make your car the best it can be, you're going to need to know how to tune. After reading this, you may not be a professional tuner, but you will know what you're doing.

Tires

The best tuning setup for tire pressure is a compromise between low pressure and high pressure. Low pressure will result in a more agile car, while high pressure will cause less grip, but a slightly higher top speed. The best way to see which works best for you is to experiment with different pressures.

Transmission

Transmission tuning is unlocked after upgrading to a Sport or Race Transmission. Tuning the final drive of your car will decide if it will have better acceleration or a higher top speed. A higher final drive will increase acceleration, but top speed will drop, and vice versa.

Alignment

Alignment impacts the grip similarly to tire pressure. Negative camber reduces understeer, increases grip, but makes the car unstable in a straight line. Positive camber decreases oversteer, but also makes the car unstable. Changing toe angle will affect the way the car enters corners. Toe-in increases stability of the car but reduces responsiveness when entering a corner. Toe-out increases responsiveness when entering corners, but the car will lose stability. Caster angle is all about straight line stability. A high caster angle enables you to have less negative camber, giving the car better acceleration and braking. With a low caster angle, you may want to consider adding negative camber in order to get more grip, other wise the car will be unstable.

Anti-Roll Bars

Anti-roll bars provide extra stability when cornering and lessen body roll around corners. A good balance between softness and stiffness is important because anti-roll bars are crucial when it comes to tuning a car for max performance. An increase in rear anti-roll bar stiffness will increase oversteer, but if they are too stiff, the wheels could come off the ground when cornering hard. Softening the anti-roll bars will make the car go around corners much easier.

Springs

Tuning of the springs on an offroad vehicle are especially important. The stiffness determines how much weight is transferred during cornering, braking, and acceleration. Stiff springs transfer more weight, but if they are too stiff, the tires could lose grip. Soft front springs decrease understeer and increase front grip. If the springs are too soft, the car will bottom out while cornering. Low ride height lowers the center of gravity and greatly improves the handling, but if you lower it too much, the car becomes uncontrollable.

Aerodynamics

Increasing downforce causes the car to stick to the road better, increasing the temperature of the tires, along with the grip. Too much downforce causes too much drag, decreasing the top speed.

Brakes

Changing the balance of braking towards the rear of the car will increase oversteer and decrease stability, however moving it towards the front will increase understeer, but increase stability.
