Introduction

Coilovers allow you to lower your car while maintaining adjustability and ride quality. This advanced modification requires mechanical knowledge and proper tools. Consider professional installation if you're not confident in your abilities.

Procedure

8 steps

  1. Step 1: Prepare and measure

    Measure your current ride height at all four corners for reference. Lift and secure the vehicle on jack stands. Remove all four wheels.

  2. Step 2: Remove front struts

    Disconnect the sway bar end links. Remove the brake line bracket. Unbolt the strut from the knuckle (usually 2 bolts). Open the hood and remove the top strut mount nuts. Carefully remove the entire strut assembly.

  3. Step 3: Disassemble the strut

    Using a spring compressor, carefully compress the spring. Remove the top nut while holding the strut shaft. Disassemble the strut, noting the order of components.

  4. Step 4: Assemble the coilover

    Follow the manufacturer's instructions to assemble the new coilover. Set the initial height adjustment. Ensure all components are properly torqued.

  5. Step 5: Install front coilovers

    Install the coilover assembly in reverse order of removal. Torque all bolts to specification. Reconnect brake lines and sway bar links.

  6. Step 6: Install rear coilovers

    The rear process varies by vehicle. Typically involves removing the rear strut/shock and spring, then installing the coilover assembly. Consult your vehicle-specific guide.

  7. Step 7: Set ride height

    Lower the vehicle and adjust the coilover height to your desired setting. Ensure all four corners are even. Bounce each corner to settle the suspension.

  8. Step 8: Get an alignment

    After installation, immediately get a professional alignment. Lowering your car significantly affects alignment angles.

Tips
  • Take photos during disassembly for reference
  • Apply penetrating oil to rusty bolts the night before
  • Start with a conservative drop - you can always go lower
  • Keep your old suspension in case you need to return to stock
