BC Racing Coilovers for the Lexus LS400

The Lexus LS400 built its reputation on refined, effortless luxury, and that same rear-wheel-drive platform makes a rewarding base for a real suspension upgrade. The factory setup prioritizes a soft, isolated ride, which leaves body roll, float, and vague control that hold the car back when you want it to feel tighter or sit lower. BC Racing coilovers for the LS400 give you adjustable ride height and 30-way damping, so you can sharpen the handling and set the stance while keeping the smooth, composed character the sedan is known for. Whether you are chasing a cleaner look or crisper control, the kit lets you tune the car to your taste.

Why the LS400 Benefits from Coilovers

From the factory, the LS400 is tuned for isolation and comfort, which shows up as body roll through corners, dive under braking, and a floaty feel over undulating roads. A set of BC Racing coilovers addresses all of it. Because ride height is set through the fully threaded shock body rather than by cutting or preloading springs, you can lower the LS400 to your target stance while keeping full suspension travel and correct damper geometry. The result is a large sedan that stays flatter and more composed, with control you can tune, without giving up the refined ride the LS400 is loved for.

Choosing the Right BC Racing Series for Your LS400

The BR Series is the best starting point for most LS400 owners, pairing 30-way combined compression and rebound adjustment with streetable spring rates that balance comfort and control for a heavy luxury sedan. The DS Series adds digressive valving for sharper low-speed response if you want a more track-leaning feel, and the ER Series brings independent compression and rebound tuning through external reservoirs for the most dedicated builds. Every kit can be ordered with custom spring rates at no extra cost, supports Swift Spring upgrades, and includes pillowball mounts with adjustable camber plates on applicable fitments for precise alignment.

FAQs

Are BC Racing coilovers good for the Lexus LS400?

Yes. BC Racing coilovers are one of the most popular and best-value handling upgrades for the LS400. They give the rear-wheel-drive platform the ride-height and damping control the factory suspension lacks, reducing body roll and float while letting you set the stance, all while preserving the smooth, comfortable ride the sedan is known for.

Which BC Racing series is best for an LS400 — BR, DS, or ER?

The BR Series is the right call for most LS400 owners, with 30-way damping and streetable spring rates that suit a heavier luxury sedan on the street. The DS Series adds digressive valving for sharper low-speed control if you want a firmer, more track-leaning feel, and the ER Series brings independent compression and rebound tuning through external reservoirs for dedicated builds.

How low do BC Racing coilovers go on the LS400?

Ride height is set through the fully threaded shock body, giving a wide, fully adjustable range rather than a single fixed drop. You keep full suspension travel at your chosen height, so the LS400 rides properly whether you drop it for a sporty look or keep it closer to stock for a classic stance. The choice of ride height is entirely yours to dial in.

Should I choose the standard rear or the True Rear option for my LS400?

The LS400 uses a divorced rear layout, where the factory spring and shock sit separately, so the standard BC Racing kit adjusts height at the rear spring perch. The True Rear option replaces that setup with a full rear coilover, combining height and damping in one unit for a cleaner install and unified adjustment front to rear. If you want the most precise rear tuning and consistent adjustability, the True Rear option is worth considering where it is offered for your LS400.

Will BC Racing coilovers fit my year of LS400?

BC Racing offers coilovers across the supported LS400 years. Always select your exact year on the listing so we match the correct kit to your car. If you are unsure which application applies to your LS400, reach out and we will confirm the right setup before you order.

Can I daily drive my LS400 on BC Racing coilovers?

Yes. The BR Series is valved and sprung to stay streetable, improving body control without sacrificing the comfortable ride the LS400 is known for. With 30 levels of damping, you can soften the car for relaxed cruising or firm it up for spirited driving, so it works well as a daily driver.

Are BC Racing coilovers rebuildable, and what warranty do they include?

BC Racing coilovers use a monotube design and are fully rebuildable, so a worn or leaking unit can be serviced rather than replaced, which is a real advantage on an older sedan. Every kit carries a 2-year warranty against manufacturing defects, handled directly through BC Racing North America.

Do I need an alignment after lowering my LS400?

Yes. Lowering the LS400 changes camber and toe, so an alignment is required to protect tire life and preserve handling. Because ride height is set through the coilover body, you keep full suspension travel at your chosen height, which makes a proper alignment easier to dial in.
