Upgrade or replace your BC Racing coilover springs with high-quality, 70mm I.D. (inner diameter) linear springs, designed for precision performance and long-term durability. Made from SAE9254 high-tensile steel, these springs feature a zinc undercoating and outer powder coating to provide superior rust resistance and reliability.

BC Racing 70mm linear springs are available in a variety of lengths ranging from 120mm to 260mm and spring rates from 3K to 20K, giving you the flexibility to fine-tune your suspension for optimal handling and ride comfort.

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.

      Bc racing springs on adlerspeed coilovers

      Still haven’t got the time set it up properly but so far, but it’s way smoother than I expected.

      The spring rates I chose are overkill fo a small sedan.But now I have a better idea of what I’m doing thanks to this purchase.

      Would recommend to anyone who wants to go for style but want the car to be functional. But keep in mind that depending on what series or brand of coil over you’ve got (since the springs can be fitted to other different brands of coilover if you know what size you’re coilover springs are).
