BC Racing Coilovers for the Lexus IS300
The Lexus IS300 blends luxury and rear-wheel-drive performance in a compact sedan, and BC Racing coilovers are the most direct way to unlock its handling potential. Engineered for superior control and responsiveness, they use a monotube damper design for faster, more consistent adjustments and offer 30 levels of damping force so you can tune compression and rebound from full soft to full stiff. Full-length height adjustment lets you set anything from a near-stock ride to a sporty, lowered stance while retaining suspension travel. The result is an IS300 that feels sharper and more planted without losing the everyday comfort that makes it such a usable sedan.
Why the IS300 Rewards a Coilover Upgrade
The IS300 has a genuinely good rear-wheel-drive chassis, but the factory suspension prioritizes comfort over control, which shows up as body roll when you drive it hard. BC Racing coilovers fix that. Fully threaded, full-length shock bodies let you set ride height independent of spring preload, so you keep full suspension travel instead of trading it away for a lower stance. The 30-way adjustable damping lets you dial in compression and rebound to reduce body roll and improve grip through corners while keeping the highway ride settled. The IS300 ends up tighter and more connected, yet still comfortable enough to daily.
Choosing Your BC Racing Series: BR, DS, or ER
BC Racing offers three series for the IS300 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. Custom spring rates come at no extra cost, Swift Spring upgrades are offered, and camber-adjustable or pillowball top mounts are available on applicable fitments.
