BC Racing BR Series Coilover Suspension Kit for 2015-2018 M3 and 2015-2019 M4 (5-Bolt Front Top Mounts)

The BC Racing BR series coilovers are designed for street driving with occasional track use. They feature easily accessible adjustment knobs and separately adjustable ride height. The BR series utilizes a mono-tube shock design, 30 levels of dampening force adjustment, and available adjustable rear camber plates. They have 46mm pistons and 53mm shock housings, spring steel valves, patented concave lower locking ring, SAE9254 high strength steel springs, T6061 Aluminum for spring locks and seats, iron lower brackets on MacPherson struts, highly polished steel piston rods, high pressure inner rod guide seals, a 2 step coating process (nickel and chromium plating), and newly developed lubricant oil. An additional bearing beneath each pillowball mount is also included. They aim to provide an affordable entry into coilover suspension without sacrificing performance, comfort, build quality, vehicle height, or handling. BC Racing selects spring rates to balance comfort and performance, avoiding oversprung suspensions. The BR Series offers 30-clicks of compression/rebound adjustment simultaneously. Front camber plates are included.
