OK, so I'm looking at springs again.
Going to Moog CC652 in front and CC667 in rear certainly tightened up the handling completely, but Fluffy ended up riding unusually high. That can't be so good.
Since you cannot get springs that are both stiffer rates and lower (or the same) ride height, I'm stuck trying to alter the new Moog springs. However, since they're much stiffer already, it gets around one problem- that of disabling part of the spring and having it bottom out too easily.
It looks like with the front springs, they're pigtail on one side and flat on the other- and I could cut a coil (or possibly two, but not advisable to do in one go) to make it go back to the stock ride height.
With the rear springs, they're pigtail on both ends and it appears like there is NOTHING I can do other than get some of those JC Whitney (or similar) spring clamps, clamp some of the coils together, and rely on the fact that they're already stiffer than stock springs and won't be bottoming out. The springs look like they have so little space between the coils that I'm not sure how you'd fit clamps in there... will have to look more closely at the real springs on the actual car.
It would be getting coils cut in front (returning to more or less stock ride height) and clamping coils in the back (also returning to basically stock ride height). In both cases the ride will continue to get harder, but I'm happy with that short of shaking the car completely apartit's not that shockingly rough now, despite the different springs.
Does this sound like I'm talking from a reality place? I'd rather get springs that are made right in the first place, but again, it seems like they don't exist so I can't really be yelled at for not having them- or for lowering the car on weak springs and bottoming out, since that's already well taken care of...
