Spring Lifespan?
I have a 2004.5 350z (I throw in the .5 because apparantly there was a change to spring rates that year). It still has the oem springs. Here is my question:
Will the spring rates have decreased appreciably in the 4 years and 50,000 miles of use? Should I plan on switching out the springs? I am upgrading to thoe Tokico blue struts, as I think the OEM struts could use replacing, but I dont know if I nescesserily need or should replace the OEM springs. If I did replace the springs I am thinking I would go with RSR, if you care to comment on that. Your thoughts would be appreciated. Thank you
