Reviews / Q&A

FAQs

Please read our FAQs page to find out more.

How much will BC Coilovers lower my car?

On average, Standard Drop allows about 1-2 inches of drop range below factory ride height. Extreme Low allows about 2-3 inches of drop.

Can BC Coilovers achieve factory ride height?

No. In most cases, factory ride height cannot be achieved.

Will the struts be valved correctly?

Yes! The shocks and/or struts are always valved to match the spring rates you choose during a custom build. There is no additional cost.

Can they be rebuilt?

Yes, all BC Racing Coilovers can be rebuilt by purchasing individual replacement parts. For example, if a strut leaks, you can simply replace the shock cartridge.

Is there rush shipping available?

Rush shipping is not offered, but all in-stock kits ship very fast— most by the next day.

Customizing the coilovers in any way will delay the shipment by a few weeks on average.
