BC Racing DS Series Coilover Kit – Mazda MX-5 Mk1/Mk2 NA/NB 1989–2005 • N-04-DS-DS

BC Racing N-04-DS-DS DS Series Coilover Kit

BC Racing DS Series coilover kit for Mazda MX-5 Mk1 NA and Mk2 / Mk2.5 NB / NB-FL 1989–2005 applications listed in the compatibility table.

The DS Series uses BC Racing's digressive piston and damping curve to provide a more track-focused suspension setup. Higher damping force at lower piston speeds helps control body roll, pitch, dive and rapid weight transfer, while the damper is designed to allow greater wheel movement at higher piston speeds over bumps and kerbs.

This complete four-corner coilover system combines monotube dampers with adjustable ride height and 30-click simultaneous compression and rebound damping adjustment, allowing the suspension setup to be tailored to the car and its intended use.

Ride height is adjusted independently from spring preload, giving greater flexibility when setting the vehicle's stance and suspension operating range. The DS Series is particularly suited to drivers looking for a more track-biased setup while retaining the adjustment available from BC Racing's single-adjustable suspension ranges.

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 full four-wheel alignment should be carried out after 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 supplied coilover adjustment spanners. Professional wheel-alignment equipment will be required for final geometry setup.

Difficulty guide: DIY Difficulty: Advanced. Installation requires removal and replacement of the front and rear suspension units, careful ride-height setup and subsequent wheel alignment. Professional installation is recommended where suitable workshop equipment or suspension setup experience is not available.

Why BC Racing? BC Racing DS Series coilovers use a digressive piston design aimed at drivers looking for increased chassis control and a more track-biased suspension setup. The combination of digressive damping, 30-click adjustment, monotube dampers and independently adjustable ride height provides extensive scope for tailoring the suspension to fast-road, track-day and motorsport use.

What’s in the box: Complete four-corner BC Racing DS Series coilover suspension kit, adjustment spanners and associated components supplied with the N-04-DS-DS kit.

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