Danno74Z Posted November 23, 2006 Share Posted November 23, 2006 Has any member used 12" (vs the 10") free length coilovers (springs) on there Z's? I don't feel it's necessary to go the 10" route in my case but any suggestions would be great. Thanks. Danno74Z Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 23, 2006 Share Posted November 23, 2006 I know it's been done before. The question is why choose one length over another. The answer to that question (as far as I am aware) basically boils down to two things. 1. Will it coil bind before the strut compresses all the way? I know this is a problem with 8" springs using rates under about 275 or 300 in lbs. I don't know what rate you have to get down to in order to start having coil binding issues with a 10" spring. Should be able to look it up and figure it out though. 2. What's the minimum weight you can get away with? If you want to minimize weight, you want to run the shortest spring that doesn't coil bind. Other than those two things, I'm not really aware of any other critical factors in deciding on a spring length. Less critical stuff like cost and availability might also be important, but not really to the way the car functions as much as to your wallet.

JustinOlson Posted November 23, 2006 Share Posted November 23, 2006 Since we are discussing this, is there a downside to run different length springs front and rear? 10" front and 8" rear?
