I have a 1989 240 wagon. Coilovers up front and I'm cutting the springs in the rear. My question is, once I cut the coils off, should I mount them just the way they came out? I read somewhere that you should switch it up so the big seat which is normally at the top is on the bottom? Any truth? And whats a decent amount of coils for being decently low? my sus[pension has basically no sag, so would 2.5 inches be okay? Thanks!
