BC Racing BR Series Coilovers for 1990-2005 Mazda MX-5 Miata (NA/NB)
SKU: N-04-BR-RS
BC Racing BR Series Coilovers for the 1990-2005 Mazda MX-5 Miata (NA/NB) are BC Racing's entry-level coilover and the most popular kit in their entire lineup, they offer the most accessible entry into adjustable coilover suspension without sacrificing performance, comfort, build quality, or handling. Every kit is extensively tested on the MX-5 NA/NB chassis and refined until it balances ride quality with performance, the reason MX-5 coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
Every BR Series kit is built around a mono-tube damper with simultaneous compression and rebound adjustment at every corner, a wide damping range without the complexity of a race-only setup. Ride height is fully adjustable independent of spring preload, so you set the stance and the ride separately. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance, you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, custom spring rates, and custom valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of customization most brands reserve for their top-tier race kits.
Since 2004, BC Racing has grown into one of the most trusted names in aftermarket coilovers, not by racing to the bottom on price, but by pairing that price with real build quality, deep customization options, and a damper design any suspension shop can rebuild instead of replacing. These MX-5 coilovers arrive tuned for the NA/NB chassis and ready to bolt in, no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts, no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.
