Maintenance and Care of Coilover Suspension

Maintenance and Care of Coilover Suspension

For most of us a set of coilovers can cost a great deal, sometimes nearly as much as the car itself if, like me, you’re into the retro scene.

Like any automotive component, coilovers require regular maintenance and proper care to ensure their longevity and optimal performance.

By following the tips and guidelines below, you can keep your coilovers in top shape, enhancing your driving experience and ensuring a safe and enjoyable journey on the road.

Essential tools

If you don’t have a C Spanner then this is an essential tool for adjusting your coilovers. I highly recommend the Tein Adjustable Wrench (available on Amazon AU). These are by far the best quality C Spanners you can buy, and you’ll thank me later.

Regular Inspection

Regular inspections of your coilover suspension are essential to identify any signs of wear, damage, or fluid leaks.

Pay close attention to the coil springs, shock absorbers, and all adjustable components.

Look for any oil leakage or signs of corrosion. If you notice any issues, address them promptly to prevent further damage and potential safety hazards.


Keeping your coilovers clean is crucial for their performance and longevity.

Regularly wash your car and make sure to clean the coilovers as well.

Use a gentle cleaning solution and a soft brush or cloth to remove any dirt, debris, or grime that may accumulate around the suspension components. You may need to jack up your car and remove the wheels for this, which I know is a faff, but is worth it.


Proper lubrication of moving parts is vital for the smooth operation of coilovers.

Check the manufacturer’s guidelines and lubricate adjustable components and joints as recommended.

Using the right type of lubricant ensures that the suspension operates without friction or unnecessary stress.


If your coilovers are adjustable, like OZ Racing coilovers, follow the manufacturer’s guidelines when making changes to the settings.

Avoid making extreme adjustments without understanding the impact on your car’s handling.

It’s essential to strike a balance between performance and comfort to maintain stability and safety during driving.

Before making any adjustments to your coilover ride height, make sure you carefully wipe away any dirt and grit from the threads with a soft damp cloth and cleaning agent.

Avoid Harsh Impacts

While coilovers are designed to handle rough roads and spirited driving, it’s essential to avoid harsh impacts whenever possible.

Hitting large potholes, speed bumps, or road debris at high speeds can place excessive stress on the suspension components and lead to premature wear or damage.

Know your roads!

Regular Wheel Alignment

Proper wheel alignment is crucial for preserving the health of your coilovers.

Regularly schedule wheel alignment checks to ensure that your suspension is working optimally and that your tyres wear evenly.

Improper wheel alignment can lead to premature wear on the suspension and tires.

Camber adjusters may be necessary, especially if you significantly drop your car, as otherwise your tyres will wear far quicker on the inside.

Winter Care

If you live in an area with harsh winter conditions (like Melbourne ;o) ), take extra care of your coilover suspension during this time.

Salt, road grime, and ice can accelerate corrosion and wear. Consider using protective coatings or covers to shield the suspension components during the winter months.

Professional Servicing

While some maintenance tasks can be done by car enthusiasts, it’s essential to have your coilover suspension professionally serviced at regular intervals.

Certified mechanics can inspect, clean, and adjust your coilovers more thoroughly, ensuring their longevity and performance.
