FH5 Tuning Guide

Brakes are an important part of the total performance picture. To be competitive, your car's brake performance must match it's power and handling. Leading the pack at the end of a straight won't help you if you can't slow down fast enough to make the next turn. These upgrades increase braking power and decrease brake fade due to excessive heat.

Spring and Dampers can make a big difference in your car's handling by maintaining optimum ride height and tire contact

Front Antiroll bars (also called antisway bars) provide extra stability when cornering. When you turn left or right, the car body tends to roll in the opposite direction. By tying the left and right sides of the suspension together, antisway bars make the car ride more level and keep one side from rolling or swaying more than the other

Rear Antiroll bars (also called antisway bars) provide extra stability when cornering. When you turn left or right, the car body tends to roll in the opposite direction. By tying the left and right sides of the suspension together, antisway bars make the car ride more level and keep one side from rolling or swaying more than the other

Chassis reinforcements stiffen the shell of the car, reducing flex when cornering, which in turn aid the suspension in keeping the maximum amount of tire on the road.

A lighter car accelerates and handles better than a heavier one. Reducing weight by removing nonessential materials or replacing stock parts with lighter ones pays off on the track.

The clutch is the vital link between the engine and the transmission. Upgrades increase the clutch's ability to handle the extra torque of a racing engine without damage.

The transmission transmits your car's power from the engine to the drive wheels. Transmission upgrades can make shifts quicker and more efficient, reduce friction and power loss, and provide better durability. These upgrades also make an audible difference.

You can improve throttle response and acceleration by decreasing the weight and inertia of driveline components, especially the driveshaft itself.

The differential allows the tires on each side of the car to turn at different rates because the inside tire travels a shorter distance around a turn than the outside tire. A limited slip differential locks at a present point to limit this difference in rotational speed, providing maximum traction under acceleration and/or deceleration.

Upgrading to tires with a softer, more aggressive compound increases traction and improves the tires' ability to maintain traction despite high heat, but also increases wear. The harder compound used in stock tires sacrifices grip to increase wear. These upgrades also make an audible difference.

In general, more rubber on the road means better traction and performance. Upgrading to a larger, wider tires provides more contact area and thus more traction. You can use wider normal-profile tires to improve traction by enlarging the tire's contact patch on the pavement. Or you can choose larger rims and low profile tires with shorter, more rigid sidewalls. These tires are less prone to deforming when acceleration and cornering forces increase. This improves traction by maintaining tread contact with the pavement.

Upgrading rims can improve handling by decreasing the wheels' unsprung weight and rotational inertia. This upgrade can also enhance performance by decreasing the overall weight of the car.

A wider spacing between the front tires can provide additional stability under lateral g force.

A wider spacing between the rear tires can provide additional stability under lateral g force.

You can upgrade your front bumper to increase the load over the front wheels by increasing downforce. These upgrades allow higher cornering speeds. Note that the level 3 upgrade makes downforce adjustable.

Upgrading the rear wing on your car increases the load over the rear wheels by generating downforce to allow higher cornering speeds. Note that the level 3 upgrade makes downforce adjustable.

Rear bumper upgrades improve handling by decreasing lift at high speeds. The level 3 upgrade also increases the load over the rear wheels by adding adjustable downforce. These changes allow higher cornering speeds.
