BC Racing Coilovers for the Lexus GS300

The Lexus GS300 pairs rear-wheel-drive balance with genuine luxury-sedan comfort, and BC Racing coilovers let you unlock its handling potential without giving up refinement. Engineered to bridge daily driving comfort and track-ready performance, these coilovers use a large 46mm piston housed in a 53mm damper body to maximize oil capacity, manage heat, and keep damping consistent as you drive. With adjustable ride height and 30-way damping, you can set the GS300 exactly where you want it, from a clean lowered stance to a firmer, more controlled setup for spirited driving. It is a straightforward way to make a heavier luxury sedan feel sharper and more planted.

Why the GS300 Rewards a Coilover Upgrade

The GS300 is a comfortable cruiser from the factory, but that softness shows up as body roll and vague control when you drive it hard. BC Racing coilovers address that directly. Fully threaded shock bodies let you set ride height independent of spring preload, so you retain full suspension travel instead of trading it away for a lower stance. The 30-way adjustable damping lets you dial in compression and rebound, reducing body roll and improving grip through corners while still keeping the highway ride settled. The result is a GS300 that feels tighter and more connected, yet remains civil enough to enjoy every day.

Choosing Your BC Racing Series: BR, DS, or ER

BC Racing offers three series for the GS300 so you can match the coilover to how you drive. The BR series is the streetable all-rounder, with 30-way combined compression and rebound adjustment and linear valving that keeps the ride livable while sharpening the chassis. The DS series adds digressive valving for sharper low-speed control and leans toward track use. The ER series separates compression and rebound through external reservoirs for dedicated track and drift builds. Pillowball upper mounts and camber-adjustable top mounts are available on applicable fitments, and custom spring rates come at no extra cost, with Swift Spring upgrades offered.

Fitment, Support, and the Springrates Guarantee

Every BC Racing coilover for the GS300 is a monotube, fully rebuildable design protected by a dust boot and backed by a two-year warranty handled through BC Racing North America. Because the GS300 uses a divorced rear, a True Rear option is available on applicable cars, and our team can help you choose the right configuration for your build.

FAQs

Are BC Racing coilovers good for the Lexus GS300?

Yes. The GS300 has a capable rear-wheel-drive chassis that is held back by a soft factory ride, and BC Racing coilovers sharpen it with adjustable ride height and 30-way damping. You get flatter cornering and more precise control while keeping enough comfort to enjoy the car as a daily driver.

Which BC Racing series is best for a GS300 — BR, DS, or ER?

The BR series suits most GS300 owners, balancing a streetable ride with meaningful handling gains through its 30-way damping. Choose the DS series if you want sharper low-speed control for track days, or the ER series for a dedicated track or drift build that benefits from separate compression and rebound tuning.

How low do BC Racing coilovers go on the GS300?

BC Racing coilovers give the GS300 a wide, fully adjustable ride-height range, so you can run a mild, functional drop or a more aggressive lowered stance. The threaded shock bodies let you set height while preserving suspension travel, so the car stays composed rather than crashing over bumps at its new ride height.

What is the difference between a standard and a True Rear setup on the GS300?

The GS300 uses a divorced rear, meaning the factory spring and shock are separate. A standard BC Racing kit retains that layout with an adjustable damper and spring, while the True Rear option replaces the divorced setup with a full rear coilover for one-piece height and damping adjustment. True Rear offers the cleanest adjustability and stance, and our team can confirm which fits your car.

Can I daily drive my GS300 on BC Racing coilovers?

Yes. The BR series is built to be streetable, and its 30-way damping lets you soften the ride for commuting or firm it up for spirited driving. Many GS300 owners run BC Racing coilovers as their everyday setup and simply adjust the damping to match the road.

Do BC Racing GS300 coilovers come with camber plates and bump stops?

BC Racing coilovers include bump stops and a dust boot to protect the dampers, and camber-adjustable or pillowball top mounts are available on applicable GS300 fitments. These let you dial in camber for better tire contact and turn-in once the sedan is lowered.

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

Yes. BC Racing coilovers use a monotube design that is fully rebuildable, so they can be serviced or revalved instead of replaced, which extends their lifespan and value. They are backed by a two-year warranty handled through BC Racing North America.

Do I need an alignment after lowering my GS300?

Yes. Changing ride height alters the suspension geometry, so an alignment is recommended after installing coilovers. A proper alignment protects your tires and ensures the GS300 handles and tracks the way it should at its new height.
