BC Racing DS Series Coilover Kit – Mazda MX-5 Mk3 NC 2006–2015 • N-11-DS-DS

BC Racing N-11-DS-DS DS Series Coilover Kit

BC Racing DS Series coilover kit for Mazda MX-5 Mk3 / Mk3.5 / Mk3.75 NC / NCEC 2006–2015 applications listed in the compatibility table.

The DS Series is BC Racing's more track-biased single-adjustable coilover range, using a digressive piston and non-linear damping curve to provide increased chassis control during demanding fast-road and track use.

The digressive damping design provides increased damping force at lower piston speeds to help control body roll, pitch, dive and weight transfer during cornering, acceleration and braking. At higher piston speeds the damping characteristic allows greater suspension movement to help the wheels respond to bumps and kerbs without transferring the full impact into the chassis.

This complete four-corner suspension kit uses monotube dampers with 30-position simultaneous compression and rebound adjustment. Ride height adjustment is independent from spring preload, providing greater flexibility when configuring the vehicle's ride height and suspension setup.

The standard N-11-DS-DS configuration uses 6 kg/mm front and 4 kg/mm rear springs. Compared with BC Racing's more road-orientated BR Series, the DS Series is aimed towards drivers looking for a more track-biased damping characteristic and increased low-speed chassis control.

Fitment advice: Designed for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC / NCEC applications from 2006–2015, including the applicable 1.8 and 2.0 petrol models listed in the compatibility table. For imported, modified or previously repaired cars, matching the vehicle generation, chassis code, suspension layout and kit reference is recommended before ordering.

Other items to consider: When fitting or setting up this product, you may also want to consider purchasing replacement suspension fasteners, anti-roll bar links, suspension bushes and any worn suspension arms or ball joints. A professional four-wheel geometry alignment should be carried out once the final ride height has been established.

Useful tools / consumables: Suitable vehicle lifting equipment and axle stands, socket and spanner set, torque wrench, penetrating fluid, anti-seize compound and the appropriate BC Racing coilover adjustment tools. Professional wheel-alignment equipment will be required for final geometry setup.

Difficulty guide: DIY Difficulty: Advanced. Installation requires removal and replacement of the complete front and rear suspension assemblies, followed by careful ride-height adjustment and suspension geometry setup. Professional installation is recommended where suitable workshop equipment or suspension experience is not available.

Why BC Racing? BC Racing DS Series suspension uses digressive piston valving to provide increased damping control at lower piston speeds, making it particularly suited to fast-road, track-day and track-focused applications. Combined with monotube dampers, independently adjustable ride height and 30-position simultaneous compression/rebound adjustment, the DS Series provides extensive scope for tailoring the suspension setup to the vehicle and its intended use.

What’s in the box: Complete four-corner BC Racing DS Series coilover suspension kit with front and rear dampers, 6 kg/mm front springs, 4 kg/mm rear springs, applicable upper mounting components, coilover adjustment tools and associated components supplied with the N-11-DS-DS kit.

Installation / setup notes: Ride height, spring preload and damping should be set methodically during installation. Once the required ride height has been established, all suspension mounting hardware should be tightened to the appropriate specification and a full four-wheel geometry alignment carried out before final suspension setup.
