Another thing comes to mind about the springs: Preload the stock springs

This will probably actually make your car ride slightly higher than OEM (if you add enough spacers) but the idea is to put (basically) a washer between the upper spring seat and the top of the spring, so that the weight of the vehicle preloads the spring rather than putting it to normal installed height.

Since the spring gains tension as it compresses (until just before it's stacked coil) having it slightly compressed at normal ride height will actually make for a slightly stiffer spring, and since the shocks bottom out before the springs reach stacked coil, you'll have the same amount of travel, meaning that you get a stiffer spring with an OEM ride height, and it only costs as much as the spacers cost to be milled. (I have a set of blue aluminum ones for 96-00 Civics, I"ll take a pic of them next time I go to the storage shed to show you what they are.)

Mine actually came in a cheap eBay set of coilovers, they're about 6mm thick (6mm of pre-tension on stock springs.) They're actually there so you can get rid of the squishy rubber mounts that go into the upper perches, but if you use them for pre-load discs, you put them in, then trim the rubber ring to fit them.
