Learning how to adjust coilovers properly is essential if you want the perfect balance of ride height, handling, comfort, and tire life. Coilovers offer far more adjustability than lowering springs, but incorrect adjustments can lead to harsh ride quality, uneven stance, poor handling, and premature tire wear.

This guide explains how to adjust coilovers the right way, including ride height adjustment, spring preload setup, and damping settings. Whether you’re dialing in your daily driver, weekend canyon carver, or track build, these steps will help you get the most out of your suspension.

What can you adjust on coilovers?

Most modern coilovers allow multiple suspension adjustments that affect ride height, handling, and comfort:

  • Ride height adjustment
  • Spring preload
  • Damping (shock stiffness)
  • Optional camber adjustment (on select applications)

How to adjust coilover ride height

How to adjust coilover ride height

Ride height adjustment allows you to raise or lower your vehicle to improve stance, handling, and center of gravity. The correct method depends on your coilover design.

Common ride height adjustment methods

  • Adjustable shock body: height is changed by threading the shock body into or out of the lower mount.
  • Spring perch adjustment: some designs use the spring perch to set ride height.

How to measure ride height correctly

  • Measure from the wheel center to the fender.
  • Record measurements for all four corners.
  • Adjust in small increments for accuracy.

Step-by-step ride height adjustment

  1. Safely lift the vehicle and support it with jack stands.
  2. Loosen the locking collar on the coilover.
  3. Adjust ride height using the proper method for your coilover design.
  4. Tighten locking collars securely.
  5. Lower the car, roll it to settle the suspension, and re-measure.

Quality kits like BC Racing coilovers are designed to maintain suspension travel while allowing precise height adjustment.

How to set coilover spring preload

Spring preload refers to how much the spring is compressed when the suspension is fully extended. Proper preload ensures the spring remains seated without reducing suspension travel.

How to set preload correctly

  1. Lift the vehicle so the suspension is unloaded.
  2. Tighten the spring perch until the spring is snug with no free play.
  3. Add minimal preload if recommended by the manufacturer. Typically this is around 5mm.
  4. Lock the collar securely.

Too little preload can cause clunking noises. Too much preload can make the ride harsh and reduce traction over uneven surfaces.

How to adjust coilover damping settings

Damping adjustment controls how quickly the suspension compresses and rebounds. This directly affects ride comfort, handling response, and body control.

How to adjust damping

  1. Locate the adjustment knob (typically on top of the strut).
  2. Turn clockwise for stiffer damping.
  3. Turn counterclockwise for softer damping.
  4. Match settings on both sides of the vehicle.

Common coilover adjustment mistakes

Lowering the car incorrectly

Using the spring perch to lower adjustable-body coilovers can reduce suspension travel and degrade ride quality.

Uneven adjustments

Always match ride height measurements and damping clicks on both sides of the vehicle.

Skipping alignment after adjustments

Changing ride height affects camber and toe. A professional alignment is essential to prevent tire wear and maintain proper handling.

What to do after adjusting coilovers

  • Drive the vehicle to let the suspension settle.
  • Re-check ride height measurements.
  • Re-torque locking collars.
  • Schedule a professional alignment.

Recommended baseline settings for street driving

  • Ride height: maintain adequate suspension travel
  • Preload: snug spring with minimal additional compression
  • Damping: start mid-range and fine-tune

FAQ: How to adjust coilovers

Does spring preload change ride height?

On most adjustable-body coilovers, preload should not be used to set ride height. Ride height is typically adjusted at the shock body or lower mount.

How many damping clicks should I use?

Start in the middle of the adjustment range and fine-tune based on comfort and handling preferences.

Do I need an alignment after adjusting coilovers?

Yes. Any significant ride height change affects alignment and can cause tire wear if not corrected.

Final thoughts

Properly adjusting coilovers improves ride quality, handling, and tire life. Small, precise adjustments combined with proper alignment will help you get the most from your suspension setup.
