Before you order: fitment and setup

Coilovers combine the spring and damper in one adjustable unit. That lets you choose your ride height and, on kits with damping adjustment, tune how firm it feels.

Fitment notes

  • 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 HKS and can change. The details above this guide are the latest we have.

Not sure it fits? Tell us exactly what you drive and we'll confirm fitment with the supplier first. It's free and saves a return.

Plan the whole job

  • 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.
  • Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.
  • The right spring rate. Compare the rates listed here with what our spring rate calculator suggests for your car's weight and use.

Questions

Will this fit my car?
Check the product title and details for the vehicles it is listed for. If you are not sure, contact us with your year, make, model and trim and we will confirm fitment with the supplier before you order.
Do I need an alignment after installing coilovers?
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?
From HKS. We sell parts from several brands and suppliers, and each one sets its own specs, lead times and warranty terms. The product details above are the latest we have.
