In the world of car customization, coilovers are a popular choice for those seeking to fine-tune their ride.
One of the key features of coilovers is their adjustability, especially when it comes to altering the ride height.
Whether you have fully threaded or partially threaded coilovers, the ability to make adjustments while they are on the car can save time and effort.
However, it’s important to ensure that the ride height is measured on both sides to maintain balance.
For those with fully threaded coilovers, corner balancing becomes essential to achieve even weight distribution. Additionally, spring preload and dampening stiffness can be adjusted to further customize the suspension.
With the use of adjustable camber strut mounts or at the lower mount, camber adjustments are also possible. While an adjustment spanner tool is the preferred choice, a flathead screwdriver and hammer can be used in a pinch.
Just keep in mind that when altering the ride height, removing the wheels may be necessary.
Types of Coilovers
Coilovers are a popular choice for car enthusiasts who want to customize their suspension settings.
These suspension components offer a wide range of adjustment settings, allowing drivers to fine-tune their vehicle’s performance and ride quality. There are two main types of coilovers: fully threaded coilovers and partially threaded coilovers.
Fully Threaded Coilovers
Fully threaded coilovers are designed with a shock body that can be adjusted to change the ride height of the vehicle.
This type of coilover allows for precise adjustment, as the entire shock body can be threaded up or down to raise or lower the car. By adjusting the height of the shock body, drivers can achieve their desired ride height and improve the overall aesthetics of their vehicle.
Partially Threaded Coilovers
On the other hand, partially threaded coilovers are equipped with adjustable spring perches.
Rather than adjusting the shock body, drivers can move the spring perches up or down to achieve the desired ride height. While these coilovers do not offer as much precise adjustment as fully threaded coilovers, they are still a popular choice for those looking to lower their vehicle.
Adjusting Fully Threaded Coilovers
To adjust fully threaded coilovers, there are several key steps that need to be followed.
By properly measuring the ride height, corner balancing the car, adjusting the spring preload, and modifying the dampening stiffness, drivers can optimize their coilovers to suit their driving preferences.
Measuring Ride Height
Before making any adjustments to the fully threaded coilovers, it is crucial to accurately measure the ride height on both sides of the vehicle.
This ensures that the coilovers are adjusted equally, providing balanced suspension performance. To measure the ride height, the distance between the center of the wheel hub and a fixed point on the vehicle’s body or chassis should be measured.
This measurement should be taken when the vehicle is loaded with the typical weight it carries.
Corner Balancing
Corner balancing is highly recommended for vehicles equipped with fully threaded coilovers.
This process involves adjusting the ride height and spring preload on each corner of the vehicle to distribute weight more evenly. By achieving a balanced weight distribution, drivers can enhance the handling and responsiveness of their car.
Adjusting Spring Preload
Spring preload refers to the pressure applied to the coilover spring when the weight of the car is not present.
To adjust the spring preload on fully threaded coilovers, the lock rings on the shock body should be loosened, allowing for the adjustment of the spring perch. By raising or lowering the coilover spring perch, the amount of preload can be increased or decreased, respectively.
It is essential to make incremental adjustments and carefully test the suspension’s performance after each adjustment.
Modifying Dampening Stiffness
Dampening stiffness plays a crucial role in controlling the compression and rebound of the suspension.
Fully threaded coilovers often feature a knob or tool for adjusting the dampening stiffness. By making adjustments to the dampening settings, drivers can fine-tune the suspension to provide the desired balance between comfort and performance.
It is recommended to make small adjustments and assess the impact on the vehicle’s handling before making further changes.
Adjusting Partially Threaded Coilovers
Adjusting partially threaded coilovers follows a slightly different process compared to fully threaded coilovers. While the ride height is still a primary adjustment, there are additional considerations such as modifying dampening stiffness and adjusting camber.
Measuring Ride Height
As with fully threaded coilovers, accurately measuring the ride height is crucial for achieving a balanced suspension setup.
By measuring the distance between the center of the wheel hub and a fixed point on the vehicle’s body or chassis, drivers can ensure equal adjustment on both sides of the car.
Modifying Dampening Stiffness
Partially threaded coilovers, like fully threaded ones, often come equipped with dampening adjustment settings.
This allows drivers to fine-tune the suspension’s dampening characteristics to match their preferences. By adjusting the dampening stiffness, drivers can customize the balance between comfort and performance.
Adjusting Camber
Camber adjustment is another crucial aspect of suspension customization.
Having the correct camber can greatly impact the vehicle’s cornering ability and tire wear. Some partially threaded coilovers offer adjustable camber strut mounts, while others can be adjusted at the lower mount.
By adjusting the camber, drivers can optimize the tire contact patch and improve the vehicle’s overall performance.
Tools Required for Coilover Adjustment
To adjust coilovers effectively, certain tools are necessary.
These tools enable drivers to make the necessary adjustments safely and accurately.
Adjustment Spanner
An adjustment spanner is a specialized tool designed specifically for coilover adjustment. This spanner allows drivers to tighten or loosen the collars on the coilovers without causing damage to the components.
It is essential to use the correct size spanner for the coilovers being adjusted to ensure a secure and precise adjustment.
Flathead Screwdriver
In some cases, a flathead screwdriver can be used as an alternative to an adjustment spanner. While not as specialized, a flathead screwdriver can still provide enough leverage to make the necessary adjustments.
However, it is critical to exercise caution when using a screwdriver, as it may not fit as securely as a dedicated spanner.
Hammer
A hammer may also be required if the adjustment collars on the coilovers are stuck or difficult to move. Light taps with a hammer can help loosen stubborn collars, allowing for easier adjustment.
However, it is crucial to use the hammer with care to avoid damaging any fragile components.
Adjusting Coilovers on the Car
Coilovers can generally be adjusted while they are installed on the car, making the process more convenient for drivers.
However, certain adjustments may require the removal of the wheels for easier access and better visibility.
Ride Height Adjustment
Both fully threaded and partially threaded coilovers can be adjusted for ride height while installed on the car. By following the proper adjustment procedures, drivers can raise or lower their vehicle to achieve their desired stance and performance characteristics.
It is important to take accurate measurements and make incremental adjustments to ensure a balanced suspension setup.
Removing Wheels for Adjustment
While ride height adjustments can be made with the wheels installed, removing the wheels can provide better access to the coilovers and make the adjustment process easier.
This allows for better visibility and maneuverability when making changes to the spring perches or shock body. However, when removing wheels, it is crucial to follow proper safety procedures, such as using jack stands and wheel chocks, to prevent accidents.
In conclusion, coilovers offer a versatile and adjustable suspension system that allows drivers to tailor their vehicle’s handling and aesthetics to their preferences. Whether using fully threaded or partially threaded coilovers, accurate measurement, careful adjustments, and proper tool usage are essential for achieving optimal suspension performance.
With the right knowledge and tools, drivers can fine-tune their coilovers to transform their driving experience and maximize their vehicle’s capabilities.
