I just swapped out the rears earlier today from the stock. I compared the 4 new springs to the stock rears; 2 were just about the same height and 2 were about 1.5 inches shorter than the stock rears. I installed the springs that were the same height since I figured the shorter ones should go on the front shocks. Can someone put my mind at ease and confirm whether the shorter springs go on the front or rear?

Second question: I have Koni SA all around and my question is which perch should I use with the strano springs?

 

Not sure what you are saying, but the front and rear springs are nothing alike (stock, anyway). You couldn't mix them up.

 

Don't use the lower Koni perch with lowering springs...it's designed for people who want to lower the front slightly without changing springs. I didn't compare my Strano springs to my stock springs...but I remember they looked distinctly different, so I'm not sure you could swap them, or if they would even fit if you swapped them...

 

The rear springs are a larger diameter than the fronts. As Rob noted, no way they could be interchanged, even accidentally.

 

Thanks guys. I had never done a spring job before so I had never seen the front springs in comparison to the rear springs. The rears I installed fit perfectly into the rubber isolator so it must be correct.

I am installing the fronts today and will use the upper perch as recommended.

Ill respond with how the setup feels this evening hopefully! From other posts I've read, ill be going full soft in the rear and 4 sweeps from full hard up front.

 

Hey, I just installed his setup a few months ago. Don't be afraid to ask any questions!
