Lower and sharpen the stance of your McLaren 600LT without sacrificing comfort or adaptive suspension function — KW’s H.A.S. adjustable spring kit replaces the stock springs and lets you dial in ride height to your preference. With this kit you get a more aggressive, planted look, improved steering response, and a sportier driving feel while retaining full use of the car’s OE dampers and adaptive suspension functions. The adjustable design lets you fine-tune height even after install, giving flexibility for track days, street use, or show-ready stance. It’s a subtle but high-impact upgrade that refines the 600LT’s handling behavior and visual presence.
Fits McLaren 600LT (2019–2021) equipped with OE lift-system / adaptive suspension.
Intended to work with the factory electronic/adaptive dampers — no need to replace shocks or suspension components.
Because of adjustable height, final ride height and alignment should be set carefully after installation to preserve handling balance and suspension geometry.
Four height-adjustable chrome-silicon steel coil springs (front + rear) matched to 600LT wheel loads.
Vehicle-specific bump stops and dust boots for both front and rear suspension.
Hardware and installation instructions needed for a clean swap using existing suspension mounts.
Spring Material: Chrome-Silicon steel, coated for corrosion resistance and durability.
Ride-Height Adjustment Range: Lowering from ~5 mm up to ~15 mm depending on vehicle load and desired stance.
Front + Rear adjustment: Both axles adjustable — allows balanced stance and tuning.
Compatibility: Works with factory adaptive/electronic suspension — no need for aftermarket dampers.
Certification / Approval (in relevant markets): Comes with approval compliance per applicable standards (e.g. homologation §19.3 where required).
Ride-height adjustability — continuous height tuning lets owners lower or restore ride height at will, tailoring the car’s stance to daily driving, spirited runs, or track use.
Preserves factory electronic suspension — because the springs are matched to the original dampers, all OEM ride-comfort and adaptive suspension functions remain intact.
Improved handling and sharper response — the slightly lower center of gravity and optimized spring rates result in more direct steering feel and better body control through corners.
Sporty, aggressive look — dropping ride height 5–15 mm gives the 600LT a more planted, purposeful stance without needing coilovers or drastic suspension mods.
Quality materials and build — built to OEM tolerances — chrome-silicon steel springs, matched spring rates, and proper bump stops/dust boots help ensure reliability and comfort over time.
Simpler, lower-cost alternative to coilovers — get adjustable height and refined handling without the complexity, cost, or maintenance of a full coilover setup.
