BC Racing BR Series Coilovers for 2008-2013 BMW 135i Convertible RWD (E88)

BC Racing BR Series Coilovers for the 2008-2013 BMW 135i Convertible RWD (E88) 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 RWD chassis and refined until it balances ride quality with performance, the reason 135i Convertible 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, spring rates, and valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of ization most brands reserve for their top-tier race kits.

BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep ization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These 135i Convertible coilovers arrive tuned for the RWD 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.
