As with any racing game, the tuning of a car is essential if you want to get the best possible performance from it. Here's our guide to the basics of tuning in Forza Motorsport 7.

1. Adjust the tyre pressure after a few laps

The tyres are an integral part of the car. All of the acceleration, braking and handling travels through the tyre to get to the road. Adjusting the pressure of the tyres can be a rather effective way of changing the grip levels of the car, but changing it too drastically can result in the handling becoming very unpredictable.
The best time to adjust the tyre pressure is after a few laps of racing, when the tyres have reached optimum temperature

2. Get the gearing right

Getting the gearing right on your car can make all the difference when it comes to finishing first or second. You can adjust the final drive ratio of the transmission depending on which track you are racing on. So, if you’re trying to maximise the top speed on the Mulsanne straight at Le Mans, moving the final drive to give the car more speed is the way to go. If you’re attempting to master the tricky corkscrew at Laguna Seca, the acceleration out of the corner is vital for a fast final sector so moving the final drive to give the car better acceleration would work in your favour.
If you want to fine tune the gearing of the car even more, you can adjust each individual gear to get every last ounce of horsepower from the engine.

3. Align your tyres

As with every racing game, the alignment of the tyre can have a huge impact on how the car behaves in the corners. However, adjusting the camber too much will also have an effect on the braking and acceleration so it’s important to find a balance. Start by adding one degree of negative camber to the front and rear then tune them to your preference.
Changing the toe will increase the responsiveness of the turn-in response of the car. Adding toe-in will move the fronts of the tyres closer together than the rears, making the car more stable but reducing the turn-in response. 
Toe-out brings the rear tyres closer together than the fronts, increasing the turn-in response but decreasing the stability of the car. So it’s essential to get the balance right to get the best cornering performance from the car. Avoid radical changes as it will wear the tyres out much quicker than normal.

4. How to tune anti-roll bars

The anti-roll bars provide extra roll stiffness when cornering. This controls the body roll of the car without affecting the load transfer when braking or acceleration is applied. Decreasing the front stiffness normally decreases the amount of understeer when cornering, while increasing the front stiffness will increase understeer. The most effective way to tune the front anti-roll bar is at the entry of the corner when the front of the car is loaded when braking.
Rear anti-roll bars work in the opposite way to the front anti-roll bars. Decreasing rear stiffness will reduce oversteer in the corners and if you increase it, the car will oversteer more. Tuning is most effective at the exit of the corner, when the rear of the car is loaded as it accelerates out of the corner.
If you’re racing on a track where there are lots of corners, the right amount of adjustment on the anti-roll bars is extremely important to get the best possible handling out of the car.

5. Adjust the springs and ride height

Combined with the anti-roll bars, the correct adjustment of the suspension will also influence how the car handles when accelerating, braking and cornering. Softening the front springs will increase grip and reduce understeer but if you soften them too much, it’s possible that the car will bottom out under heavy braking, which will make the car very unstable when transitioning from left to right. 
If you increase the stiffness too much, the car will be unstable over rough surfaces and curbing. For example, if you’re driving a front-wheel-drive car, some adjustment to the front springs will provide more grip towards the front of the car which will improve overall handling.
Softening the rear springs will increase the rear grip of the car while reducing oversteer, but too much change and the car will bottom out under acceleration, making the car unstable. Having driven the rear wheel drive Porsche 911 GT2RS, a slight adjustment to the rear springs made the car much more stable when cornering.
The ride height of the car determines the ground clearance of the car and its centre of gravity. The trick with adjusting the ride height is to make it as low as possible without the car bottoming out and suddenly losing control. Raising the front ride height may help in heavy braking situations while adjusting the rear ride height will help with rear weight transfer when accelerating heavily.

6. Get the damping right

Rebound damping controls how quickly the suspension of the car expands when the wheel moves away from the car as the inside wheels would during a turn or as the rear wheels would when braking. When adjusting the damping, it’s best to start with the bump damping first, then adjust the rebound damping.
Lower the car’s rebound damping until it transitions harshly though a tight chicane. Then slowly raise it until the harsh transition begins to smooth out. If the rebound damping is set too high, the front of the car will become unstable and understeer a lot when quickly changing direction.
Bump damping controls how quickly the car’s suspension compresses when the wheel moves towards the car. Like the rebound damping, start off with a low setting and slowly increase it so tyre contact across bumps, curbs and harsh transitions is smooth. If you increase the bump damping too much, it will cause the tyre to bounce across the bumps, making the car very difficult to control.
There you have it – there are lots of different tuning options which depend on which car you’re driving, what the conditions are and which track you’re racing on. Experiment with different tuning options but once you find that perfect setup, you’re all set!
