Forza Horizon 4 How to Tune Cars
Great tuning can give you an edge in online races or shave seconds off your track times.
Forza Horizon 4 offers a deep level of customization when it comes to car upgrades and tuning. Whether you’ve got a stock vehicle or one that’s been highly modified with upgrades you can tune cars to your specific liking in a number of different areas.
You can tweak things like tires, alignment, roll bars, springs, damping, areodynamics, braking, and differential. All of these options will impact your car in different ways.
Tire tuning allows you to select the PSI for your front and rear tires. Setting tire pressure higher increases speed and responsiveness of the car, but can also lead to sudden loss of grip. Setting pressure lower can cause the tires to heat faster but can reduce responsiveness.
Gears in Forza Horizon can be adjusted to provide better top speeds or more acceleration. These can be adjusted one by one, manually, or can be done through the Final Drive gear ratio which will basically allow you to decide whether you want a car with high top speed or high acceleration.
Changing the alignment of a vehicle in Horizon 4 can be a little bit daunting as there are multiple options to deal with in Front and Rear Camber, Front and Rear Toe, and Front Caster. Changing any of these options will have drastic impact on who your car performs on straight lines and in corners. Negative camber will do things like reduce understeer and increase corning at the cost of having less control on straight aways. Positive Camber on the other can reduce oversteer but also end up making the car unstable.
Antiroll bars can give you extra stability when taking corners. Antisway bars can be adjusted to be soft or stiff for both the front and rear of the car. Decreasing stiffness will result in reducing oversteer. Increasing stiffness can increase oversteer.
Adjusting springs have a bunch of different options as well. You can make them soft or stiff in the front and rear, but you can also adjust the ride height of the vehicle here as well.
Downforce can be adjusted in Horizon 4 to help with more speed or give a car better handling in corners. Adjustments can be made in the front and rear of the car. Increasing downforce can keep your car more grounded, while heating tires more quickly and improving handling. The downside is that too much downforce will cause excessive drag which can then decrease maximum speed, increase tire wear and fuel consumption.
Braking will help your car stop faster with Braking Force adjustments that can be made to balance and pressure of the brakes themselves. This can help with braking distance as well as understeer and oversteer for your car. Adjusting breaking balance from front to rear will reduce car stability and give a bit of oversteer under heavy braking. Moving from rear to front will increase stability with a big bump to understeer.
You can access all of the tuning options from the upgrades section of the game’s menu. Here a small tab labeled tuning will allow you to experiment with different options. You can also find new community tunes or store different tunes to apply on vehicles. As each tune works differently depending on the car, the best bet is to try out some different tuning options on the road to see how changes have impacted the vehicle.
