stupid suspension question: which springs are front?

[PlanZero]

So I just got some 1.3" lowering springs to replace the crappy coilovers on my car, but which ones are for the front and which ones are for the rear? One pair is slightly shorter, wider and stiffer than the other pair. I assume these are the front. The reason I ask is that the serial # on those ends in "R" and the others end in "F" not sure why

Press down on each set and see which one is easier to compress. The lower springrate goes in the rear.

The ones with the thicker coils should be the fronts.

I bought a set of "ebay brand" springs because they were advertised as a 1" drop..... Well, they ended up being more like 2", but anyway it was the same deal. The ones with the printed number that ended with "R" had the thicker coils and were noticeably stiffer than the ones that ended with "F"

The wider spring is front and skinny taller spring is rear.
