SF Racing Air Struts for the 2006-2011 Honda Civic Si (FA5/FG2) are the best coilovers available for street-driven cars. SF Sport Coilovers were designed to give a wide range of ride height adjustability without reducing the spring travel. Each corner of the car has 32 levels (or clicks) of damping adjustability. This combines both the rebound and compression into one adjustment knob. The coilovers also use rubber top mounts to help reduce the noise that typically comes with high performance aftermarket coilovers. SF Coilovers come standard with an anodized coating to protect against rust and corrosion caused by extreme use and harsh external elements.

SF Racing parts are manufactured from high quality products sourced from around the world while still maintaining a very affordable price. SF Racing Sport Coilovers are the perfect setup for your daily driver.

Features

  • Monotube Damper Design – Improves heat dissipation and reduces oil leakage.
  • 32-Level Adjustable Damping – Fine-tune rebound and compression for ideal ride quality.
  • Adjustable Ride Height – Lowers 1-2.5 inches below factory height without sacrificing suspension travel.
  • Independent Lower Mount Adjustment – Maintains shock and spring integrity while adjusting height.
  • T6-6061 Aluminum Construction – Lightweight, corrosion-resistant anodized top mounts, perches, and collars.
  • Electroplated Shock Body – Zinc-coated for rust protection.
  • Low-Friction, Pressure-Resistant Housing – Ensures smooth damping and longevity.
  • Pillowball or Reinforced Rubber Top Mounts – Reduces noise while improving handling.
  • SAE9254 Japanese Cold-Wound Springs – Durable and consistent performance.

About this air suspension kit for the Honda Civic Si

This SF Racing setup swaps the steel springs for air springs, so ride height is set with air pressure rather than a fixed spring.

Fitment notes

  • Listed for: 2006-2011 Honda Civic Si (FA5/FG2).
  • Model years: 2006-2011. Check your car's year falls inside this range.
  • Chassis code FA5/FG2: the same model name is often used across several chassis codes, so match the code, not just the name.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.
  • Specs, lead time and warranty come from SF Racing and can change. The details above this guide are the latest we have.

What else to plan for

  • An alignment. Any change in ride height changes camber and toe. Set your final height first, then align.
  • Camber and toe adjustment. Bigger drops often need adjustable arms or camber plates to align properly. See alignment and camber kits.
  • Management. Air struts need a compressor, tank and controller unless the listing says they're included.
  • Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels.

Questions about Honda Civic Si air suspension

Will this fit my Honda Civic Si?
It is listed for the 2006-2011 Honda Civic Si (FA5/FG2). Check your year, model, drivetrain and chassis code against the product title. If anything is different, contact us and we will confirm fitment with the supplier before you order.
Do I need an alignment after installing air suspension?
Yes. Changing ride height changes camber and toe. Set your final height, let the suspension settle, then get the car aligned.
How low can I go?
It depends on the adjustment range the brand lists, your wheels and tires, and how you use the car. Most cars that are driven hard work best with a modest drop that leaves enough suspension travel.
Where do specs and warranty details come from?
