Spring Coil Bind, also known as spring sag Options

[BonzaiCelica]

So i purchased these TRD front Springs 48131-ST001(@ 4.1kg spring rate) for my superstrut conversion. So i didnt see rust when i bought them until i received them. So now that i've learned about coil bind/sagging from sport springs. You wouldn't think it would happen to good quality TRD Springs. pics as follow. so basically what can i do? i've read from an Subaru Forum that you can definetly tell if the springs are bad unless you get the manufacture specs of the distance between each coil. I've read that EIBACH and TRD springs are one in the same, is this true?? the length of TRD spring measure in @ 24.5 cm and claim a 1 inch drop and Stock ST205 springs are 30.5cm @ 2.5kg spring rate.

ah yes rusty correction i had it wrong but you were slightly off too(i corrected the first post). I assumed it was 3.9kg because it was superstrut, but they were actually mcpherson springs on his superstrut suspension(perhaps his local parts store he bought them from didnt have the specific trd superstrut springs in stock and he just settle for mcpherson TRD spring rate which are .2kg softer

So correction the TRD front springs i have are 4.1kg
