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.
Tools Required
- Spring compressor
- Socket set
- Torque wrench
- Jack and jack stands
- Penetrating oil
- Impact wrench (recommended)
Parts Required
-
Coilover suspension kit
-
Alignment
Safety Warnings
- ⚠ Spring compressors can be dangerous if used improperly
- ⚠ Lowering your car may affect ground clearance and drivability
- ⚠ Always get a professional alignment after installation
- ⚠ Some coilovers require periodic maintenance
Step-by-Step Instructions
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 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 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 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 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 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 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 Get an alignment
After installation, immediately get a professional alignment. Lowering your car significantly affects alignment angles.
Pro 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
