BC Racing Coilovers: Implications of Ordering Custom Spring Rates

Many people are aware that BC Racing will allow you to customize your coilovers to your liking. Here are a few things to keep in mind when considering a custom BC kit.

  • Swift Springs upgrade is mandatory for rates above 18k. This is because BC does not make a wide variety of springs (length, diameter) at rates above 18k. The Swift Spring upgrade does come at an increase cost as well.
  • Off the shelf, your kit can handle spring changes of 2-4k in each direction. Beyond that will require shocks with different valving.
  • Any kit that varies in specification from its "Off the Shelf" version is considered a custom kit. These are not eligible for cancellation or return once your order has been processed, and the build time will be 2-3 weeks. You must be committed to your custom kit, so be sure to think about this before you place your order!

With this information, you see that BC Racing has a lot of flexibility and capability when it comes to building a kit tailored to your specific needs. Heeltoeauto.com is the place to go for all your BC Racing needs, from mild to wild.

I want to add swiss springs but I don't know what "spring rate" means I have an 04 tl maybe you can give some good advice?
Administrator Note:
"Spring rate" is the amount of weight required to deflect a spring one inch. The lower the Spring Rate, the softer the spring. The softer the spring, the smoother the ride. So basically, it is a measure of how stiff or soft the spring is.

For coilover packages that come with springs we normally recommend keeping with the standard rates that come with the kits. These springs have been chosen to give a good ride and handling balance. It is very hard to tell you what rates you would choose in a custom application before you had something in there to compare against.

While choosing custom rates is a vogue and we do offer that option, many people choosing this option are not doing so at our recommendation.

What are the max number on spring rates I can get before revalving ? For a 2006 Acura tsx
Administrator Note:
Two up or two down, and after that there would be it before you would need to revalve.
