Whether you're driving on the road or track, changing the springs on your HSD coilovers is a great way to alter their handling characteristics. Replacement springs are sold in a range of length and stiffness (measured in kg/mm). If you have any questions regarding the required length for your HSD kit be sure to get in contact!
If you aren't sure which springs you require, select the "HSD Springs - Other" option and be sure to tell us what car you have and which spring rates you require in the Order Comments section.
(dimensions differ for inboard rear setups)
Internal diameter 65mm
External diameter 90mm
E39 front coilovers use CS2 sized springs!
Please note that HSD springs are sold in pairs.
