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. We highly recommend ensuring your struts are properly valved to match your chosen spring rates. If you're increasing or decreasing spring rates by 4k or more, it's best to revalve your struts accordingly. Failing to properly match your springs and struts can lead to coilover damage, reduced performance, a noticeably harsher ride, and may void the warranty.
