Product Information
ABOUT ST X COILOVERS
ST X Coilovers combine adjustable lowering with a matched spring and damper package, giving your car a more purposeful stance and a sportier driving feel. Manufactured by KW automotive, they bring proven suspension engineering to an accessible, straightforward coilover upgrade.
With damping preset for your vehicle, ST X lets you focus on getting the ride height right while enjoying a balanced setup for everyday road use.
SPORTY HANDLING, STRAIGHTFORWARD SETUP
ST develops the fixed damping characteristics to work with the supplied springs, improving steering response and body control while retaining everyday usability.
There are no manual damping settings to configure. The spring and damper combination provides a defined balance of comfort and sportiness, making ST X a practical choice for drivers who want a complete suspension upgrade with minimal setup.
SET YOUR STANCE
Continuous height adjustment lets you refine the lowering within the kit’s specified range. You can adjust the ride height after installation to suit your preferred appearance and wheel and tyre combination.
Threaded adjusters and durable composite spring seats provide precise adjustment, with the available front and rear lowering ranges listed in Key Details.
KW ENGINEERING, ST CONSTRUCTION
ST X uses galvanised steel strut housings with additional sealing for corrosion protection. Polyamide composite spring seats with stainless steel inserts help maintain the function of the height adjusters.
The dampers incorporate low-friction components, while dust protection and bump stops help protect the suspension during regular use.
MAKE IT YOURS
Personalise your kit with optional spring colours and individual spring markings. ST’s customisation options let you carry your build’s style through to the suspension.
Available options are listed on the product page. Customised orders require additional production time.

ST X COILOVERS OR LOWERING SPRINGS?
Lowering springs retain your original dampers and provide a predetermined reduction in ride height. Height adjustable spring kits add the ability to fine-tune that lowering.
ST X replaces both the springs and dampers with a matched package. It suits drivers who want adjustable ride height together with ST-developed damping, rather than retaining the original dampers.
Please refer to the Key Details section and model compatibility list for this kit’s lowering range, suspension requirements and fitment restrictions.
