Before you order: Lexus IS300 fitment and setup
For a Lexus IS300 that needs to be low for shows and practical for daily driving, air suspension is the most flexible option.
Fitment notes
- Listed for: 2017+ Lexus IS300 RWD (ASE30).
- Model years: 2017+. Newer years can change parts mid-generation, so match the exact year.
- Chassis code ASE30: parts for other chassis codes of the same model usually won't fit.
- Drivetrain: RWD. RWD and AWD versions of the same car often take different parts.
- 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.

- 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. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.

Questions about Lexus IS300 air suspension
Will this fit my Lexus IS300?
It is listed for the 2017+ Lexus IS300 RWD (ASE30). 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?
From SF Racing. 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.
