Hey guys i have a civic w/ a H23 motor in it. My suspension is GC w/ Yellow Koni in the front & AGX in the rear.
My question is can i put the springs from the front on the rear and get a stiffer (400lbs) springs in the front from gc?
It can be done but I wouldnt recommend it. Its not the same size length and could more than likely take you out of the normal range of travel for the strut.
ones in the rear should be harder than the ones up front already.... and if your GC sleeves were anything like mine, the spring diameter sure as hell looked the same. I must admit I never measured though.
