Hi been lurking around the forums for a while and have pm'ed few people when I had questions but I figure I could try posting. I recently bought a set of KW Clubsports as well as the spl rear mid links. The rear KW springs doesn't fit the spring perch, (KW springs ID 61mm, need 65mm/2.5"). So I want to purchase swift springs in 2.5" ID. The problem is I'm not sure what length to buy. The KW springs are 8" in length but there are also helper springs which are 20 n/mm, 80mm uncompressed and 35mm compressed. Should I just purchase the swift springs in 8" and buy swift helper springs at 60mm uncompressed and 24mm compressed at 14.7 n/mm? Will the difference in the helper springs affect any performance or I can just fix it by adjusting the height with the spl rear mid link? or should i just buy a longer swift spring like say a 9" spring?

Thanks in advance for all that reply with help.

 

You have the spl mid links, grab a 8-9inch spring depending on rate. You can adjust height with the mid links

 

Call and talk to SPL , they will know what you need. I have a feeling you are way over your head, considering you don't know what a helper spring does.

 

I second this ^

 

Thanks, called SPL they referred me to their spring calculator under their tech section. Problem solved.
