Rabbit's very first post spells out clearly what he's seeking.

What do you guys think? This thing is already kind of choppy, but it could possibly do okay with a little lowering...
Someone should have said lowering in theory improves fe but in practice the results, if any, are too small to notice.

Additionally, if he already thinks the ride is kind of choppy, lowering it is only going to make it moreso. It doesn't matter if the springs are cut or if aftermarket springs are bought; when a typical car has perhaps 4" of bounce travel and 1"-2" are taken away, it is obvious that the spring rate needs to increase or the bump stops will be hit with some regularity. Progressive rate springs may allow the first wee bit of travel to remain soft but the Piper must be paid and any larger bumps will be harsher yet. The only ways around having higher spring rates are drop spindles with otherwise stock parts, re-hacking the suspension points themselves, running smaller diameter wheels and/or tires, or thinking that having soft rate springs and bouncing off the bumps stops is acceptable.

Then we get into the bought vs cut springs crap yet again, with yet another failure to explain just what it is that makes buying aftermarket springs superior to cutting stock ones (as if it hasn't been clearly refuted already).

The first page of this thread contains little more than pure crap.
