Product Details

Ready to enhance your BC Racing Coilovers with Swift Springs or adjust your spring rates for a tailored ride? Look no further. These performance coilovers upgrades are designed to take your tuning game to the next level.

Swift Springs are a trusted name in the performance tuning world, backed by over 90 years of industrial spring manufacturing expertise. Our engineers have fine-tuned every detail, crafting coilover springs that are lightweight, durable, and compliant—while maintaining consistent linear spring rates.

Swapping springs might typically mean a stiffer or softer feel, but Swift Springs for BC Racing Coilovers deliver more: improved traction, smoother weight transfer, superior ride quality, lower tire temperatures, and a predictable driving experience. These aren’t just springs—they’re a performance upgrade engineered for enthusiasts who demand the best.

Made from our advanced (H5S.TW.) material—outperforming standard silicone chrome steel—these tuning springs use fewer coils to cut un-sprung weight and maximize stroke. The result? A lighter, more responsive setup for your BC Racing Coilovers.

Important: We strongly recommend to shop by spring size instead of vehicle.

Additional Notes

  • Customize at your own discretion. Please ensure you are selecting the right specs when customizing your coilovers.
  • It's highly recommended to ensure your struts are valved for the rates you are choosing. If you change the spring rates by 4k or more, it's also recommended to change the valving. Failure to properly pair your springs and struts can damage your coilovers, hinder performance, and reduce ride quality.

      Great upgrade for my FG2 Civic Si

      For years now I’ve had the default BC Racing BR series coilovers, which came in 6k rates front and rear. It’s a perfect amount for driving every day but because of the suspension design it was a bit too soft in the rear. I upgraded to these with 8k rates to not overload the shock absorber. Now it handles better and rubs much less when I have cargo or passengers. Still soaks up bumps well.
