BC Racing RM Series Coilovers for 2015-2023 Ford Mustang w/o MagneRide (S550)

BC Racing RM Series Coilovers for the 2015-2023 Ford Mustang (S550) are purpose-built for McPherson-strut cars that see serious track time, with an inverted mono-tube damper engineered to outlast a hard season of lateral loads. Every kit is extensively tested on the Mustang S550 chassis and refined until it balances ride quality with performance, the reason Mustang coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

The RM Series inverts the mono-tube damper on strut-equipped chassis, putting the heavy internals where the lateral loads are worst. A wider piston shaft than conventional uprights means more consistent damping on long sessions and more fatigue life before rebuild. Where BC Racing separates itself is tuning philosophy: every off-the-shelf spring rate and damper setup is chosen to stay comfortable on daily roads while still delivering real performance at the track. If you want something different, Swift Springs, rates, and valving are all options at checkout, BC will match the valving of the dampers to whatever springs you pick, something most brands don”t offer outside their flagship race lineup.

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 ization options, and a damper design any suspension shop can rebuild instead of replacing. These Mustang coilovers arrive tuned for the S550 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.
