Hey everyone, just looking to see if someone can answer this for me. I am looking into getting a set of PSS9s or PSS coils but I am not too excited about the lower spring rates. Currently I am running GC coil conversion with eibach springs. I really want to keep the spring rates I have so I want to know if I can just throw the springs I have now on the PSS or PSS9s?

Thanks in advance!

The Eibach springs are likely 2.25" ID or 2.5" ID. What are the spring part numbers you are using? The spring P/N format should be "XXX.YYY.ZZZ", where XXX is the spring length in inches, YYY is the spring ID in inches, and the ZZZ is the spring rate in lb/in. 700.250.600 is a 7.0" long spring with a 2.5" ID and a spring rate of 600 lb/in.

You would need to have the lower perches of the PSS9 machined for the ID of the springs you're using. You can likely adapt your current Ground Control top hats to work with the PSS9s.

I had the info written down somewhere. I would need to remove my wheels to double check. All I remember is the weight bearing of 440 front and 380 rear when i looked it up on Ground controls website. I will try to measure them this weekend and get back to this thread to post more info.
