Mitchy Posted March 28, 2020 Share Posted March 28, 2020 Can anybody shed some light on front springs’ loaded and unloaded lengths? I am about to swap the tired old original struts and springs for new KYB Legacy Outback struts and KYB Forester SF springs. Being a non-standard set-up, I am taking measurement before disassembly; The original front springs under the weight of the car show an overall length of 18-20cm (~7.5”). The brand new new uncompressed spring measures 38cm (15”). Can I expect the new springs to compress to almost half their length??? This, combined with Outback struts which give an extra 0.5” spring perch height, would appear to give me some brutal lift. Obviously the strut will limit the length of the spring to some extent. I’m hoping for some lift at the soft front end, but perhaps this will be too much. PS the rears were done earlier using the same combination of new KYB springs and Legacy Outback struts, and gave me around 2” of clearance, tire-top to wheel arch, no lift spacers. Thanks for any theories or knowledge in this matter. New versus old. Both new and old springs have roughly four turns: Quote Link to comment Share on other sites More sharing options...
