- Vehicle Fitment
BC Racing BR Series Coilovers for the 1997-2001 Infiniti Q45 (Y33) offer the most affordable entry into coilover suspension without sacrificing performance, comfort, build quality, vehicle height, or handling. This is done by extensively testing each vehicle, then refining the coilover characteristics as many times as needed to ensure the most well-balanced and affordable aftermarket suspension conceivable.
BC Racing takes great pride in choosing spring rates for our off-the-shelf kits that strike the perfect balance between comfort and performance so you're never stuck with an oversprung suspension like many other brands sell. BC Racing offers one of the widest ranges of damping adjustment with 30-clicks of compression/rebound adjusted simultaneously on the BR Series.
With meticulously chosen spring rates, damper valving, and one of the widest adjustment ranges in the industry, you can't go wrong with the BC Racing BR Series Coilover System. BC Racing BR Series is the most popular coilover option from BC Racing.

Questions & AnswersAsk a Question
I have a 2001 Infiniti Q45t (Touring) will these BC Racing BR coilovers fit my vehicle
Yes. The suspension mounts are the same as the other trims.
Can I replace lower coilover mount from a different vehicle to fit my specification
We cannot advise on mixing and matching components. BC Racing will only guarantee fitment on the vehicles for which they are built. Individual components (or replacement parts) for BC Racing Coilovers can only be purchased direct from BC Racing North America (https://www.bcracing-na.com).
Will these work on a 99 Q45T ?
The Q45T uses a bigger front hub so the weld-in version would have to be used. The SKU is V-05-BR.
