H&R and Dinan spring questions

[robrez]

First off, is anyone familiar with a blue H&R rear spring #19.03? From what I gather, they are German-spec vert and/or ix springs. They have the thicker coils that don't stack up in the middle. I'm trying to get an idea of how much of a drop to expect on my m42 sedan.

Secondly, anyone have experience with Dinan springs? I know people like to trash on Dinan because it's expensive, but they have the springs on sale right now for 35% off and an additional 15% rebate, making them about $200 a set. So they are competively priced for once. Anyone drove on them and/or know how much drop to expect. Thanks

Here is a pic of the blue H&R springs. From left to right are stock M42 springs, stock Z3 coupe springs, H&R 50406, and H&R 19.03. As you can see the blue H&Rs are the shortest, however, I doubt they'd sit lower than the 50406s since the middle 50406 springs compress onto each other under load. I'm pretty sure they have "sport" spring rates. Also, if anyone wants the Z3 springs cheap, PM me. They'll only give a .5 to .75 inch drop though.
