The Complete BC Racing Coilover Guide for Infiniti
The Q50 has four BC Racing listings, split three ways: whether the factory Dynamic Damping System is fitted, whether the drivetrain is AWD or RWD, and whether the car has the 2.0T four-cylinder. The part numbers are not interchangeable. Sort that out first and the rest of the Infiniti range is manageable.
Twenty-nine fitments across 26 models, all of them on BR. The G37 standard kit, the G37 True Rear Coilover variant, and the M35/M45 on the Y50 platform (2006 to 2010) also have ER and ZX. The first-generation FX35 (S50, 2003 to 2008) is the only RM fitment in the range.
Which BC series fits your Infiniti
BR is available on all 29 Infiniti fitments. Three of those fitments also carry ER and ZX: the G37 standard kit, the G37 True Rear Coilover variant, and the M35/M45 on the Y50 platform (2006 to 2010). The first-generation FX35 (S50, 2003 to 2008) is the only fitment in the range with RM available. Everything else is BR only.

All 29 BC Racing coilover fitments for Infiniti
What to check before you order
Three things to sort on the Infiniti range before going to the part number.
Q50 and the Dynamic Damping System. The AWD Q50 sits on the HNV37 chassis and BC Racing lists it twice depending on whether the factory DDS is fitted: W/ Dds for cars that have it, Wo/ Dds for cars that do not. These two kits use different lower mount configurations. The Q50 also has a separate listing for the RWD drivetrain (HV37) and another for the 2.0T four-cylinder (ZV37). If you are not sure whether your Q50 has the DDS, look for a wiring harness connector on the front damper body. If you need help identifying the spec before ordering, drop us an email or click to open a chat and we’ll help you confirm it.
FX35 and FX50S CDC status. The second-generation FX35 (S51, 2009 to 2017) appears twice in the range: W/O CDC for cars without Continuously Damped Control, and separately the FX50S (the V8 model) which is listed only in the W/ CDC configuration. The QX70 (2013 to 2017) sits on the same S51 platform and has its own dedicated listing. If you are ordering for a QX70, use the QX70 listing rather than the FX35 S51 entries.
G37 standard kit vs True Rear Coilover. Two listings cover the same G37 (V36, 2007 to 2015). The standard kit works with the factory rear mounting geometry. The True Rear Coilover replaces the rear shock-and-spring arrangement with a full coilover unit, giving you damper adjustability at both ends. Both listings are available in BR, ER and ZX. The AWD G37 and the Convertible are on separate BR-only kits.
BC Racing coilovers for the Infiniti Q50
Four BC Racing kits for the Q50, each covering a specific combination of DDS status, drivetrain and engine. The AWD Q50 on the HNV37 chassis is listed twice: W/ Dds for cars with the factory Dynamic Damping System fitted, Wo/ Dds for cars without it. The RWD Q50 (HV37) has its own single listing. The 2.0T four-cylinder (ZV37) has its own kit. Confirm which applies to your car before selecting.
BC Racing coilovers for the Infiniti G37
Four BC Racing kits for the G37 on the V36 platform (2007 to 2015). The standard kit and the True Rear Coilover cover the same chassis and years but use different rear configurations: the True Rear Coilover replaces the factory shock-and-spring rear setup with a full coilover unit. Both are available in BR, ER and ZX. The AWD G37 (2009 to 2015) and the Convertible are separate BR-only listings.

BC Racing coilovers for all other Infiniti models
The wider Infiniti range covers the FX35 and FX50S across two platform generations (S50 and S51), the QX70 (S51 platform, 2013 to 2017), the Q45 in two chassis generations (Y33 and F50), the M-series across three platform codes (Y34, Y50, Y51), both Q60 variants (Front Eyelet and 2.0T Front Fork), the EX35 in RWD and AWD, the G35 AWD, the Q30 and the second-generation QX50. The M35/M45 on the Y50 platform (2006 to 2010) carries BR, ER and ZX; the first-generation FX35 on the S50 (2003 to 2008) carries BR and RM. Everything else in this group is BR only.
Final thoughts
Twenty-nine Infiniti fitments, all on BR, with three models stepping up to ER and ZX and one to RM. The Q50 is the make’s most split model: four listings across two chassis codes, separated by DDS status, drivetrain and engine. Get those confirmed before selecting a kit. On the G37, the True Rear Coilover listing is there if you want a full coilover unit at the rear of a V36. Everything else resolves from the fitment table by model, year and chassis code.
