Operating Your Eibach Pro-Street-S Coilovers

The Eibach Pro-Street-S Coilover Kit provides adjustable ride height, allowing you to customize your vehicle's stance and handling characteristics.

Ride Height Adjustment

Ride height is adjusted by rotating the spring perch on the threaded shock body. Lowering the vehicle will generally result in a firmer ride and improved cornering stability. Raising the vehicle will increase ground clearance.

• Always adjust both sides of an axle (front or rear) equally to maintain vehicle balance.
• After any significant height adjustment, a wheel alignment is required.
• Do not exceed the minimum or maximum ride height recommendations provided by Eibach to ensure safe operation and prevent damage.

Maintenance

Regular inspection and maintenance will prolong the life and performance of your Eibach Pro-Street-S Coilover Kit.

• Regular Inspection: Periodically inspect all suspension components for signs of wear, damage, or leaks. Check for loose bolts or nuts.
• Cleaning: Keep the coilover bodies and springs clean from dirt, salt, and debris, especially in harsh weather conditions. Use mild soap and water.
• Corrosion Protection: In areas with road salt or high humidity, consider applying a corrosion-inhibiting spray to exposed metal parts, avoiding seals.
• Re-torque: After the initial installation and after approximately 500-1000 miles, re-torque all suspension fasteners to the manufacturer's specifications.

Troubleshooting Common Issues

Noise from Suspension

• Cause: Loose fasteners, worn bushings, or components rubbing.
• Solution: Inspect all mounting points and fasteners for proper torque. Check for any contact between suspension components and other vehicle parts.

Uneven Ride Height

• Cause: Unequal adjustment, settled springs, or damaged components.
• Solution: Measure ride height at all four corners and adjust as necessary. Ensure adjustments are made on a level surface.

Poor Handling or Premature Tire Wear

• Cause: Incorrect wheel alignment, improper tire pressure, or damaged suspension components.
• Solution: Have a professional wheel alignment performed. Check tire pressures. Inspect for any damaged or worn parts.

If you experience persistent issues, consult a qualified automotive technician or contact Eibach customer support.
