BC Racing Coilovers for the Mazda Miata
The Mazda MX-5 Miata is the definitive lightweight roadster, built since 1989 around Mazda's "Jinba Ittai" philosophy of horse and rider as one. Its low weight and rear-wheel-drive balance make it endlessly rewarding to drive, and BC Racing coilovers are one of the best ways to sharpen that connection. A coilover kit gives you independent ride-height control at each corner, so you can set a level ride or add rake and even corner-balance the car with your weight in the seat. From the NA to the ND, BC Racing coilovers help the Miata do what it already does best, only tighter and more precise.
Why the Miata Rewards a Coilover Upgrade
The Miata's magic is its light, communicative chassis, and a good coilover setup amplifies it. BC Racing coilovers use fully threaded shock bodies, so you set ride height independent of spring preload and keep full suspension travel rather than trading grip for a lower stance. Because you control each corner independently, you can level the car, add a touch of rake, and even corner-balance it for consistent handling. Lowering the Miata reduces body roll and flattens it through corners, while adjustable damping lets you keep a firm but comfortable street ride or stiffen things up for spirited driving and light motorsport use.
Choosing Your BC Racing Series: BR, DS, or ER
BC Racing offers three series so you can match the coilover to your Miata and your goals. The BR series is the streetable all-rounder, with 30-way combined compression and rebound adjustment and linear valving that stays comfortable enough to daily while sharpening the car when you push. The DS series uses 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 work. Custom spring rates are available at no extra cost, with Swift Spring upgrades offered for fine-tuning the ride.
