Unfortunately I have not found a good resource as to spell out the differnces in the springs. However, there is certainly a difference, as there has to be for all zsp equipped cars to ride close to the same height yet weigh different amounts depending on engine/trans. D6 is a fine spring to run up front and will give you the desired drop (on a 335). I am just thinking the D2 will give you an ass down look, as it is only seen on coupes (wait...I was assuming you had sedan, if you have coupe you are all set then). Anyhow, the best advice I can give to someone trying to figure out which springs to get is go to the local dealer when closed and snoop around the cars on the lot and see what has what. That is what I did.

Here's an intersting, yet crappy, pic. I just swapped the front springs back to stock with the lowering perches, but left the H&R rear springs as I was running out of time today. It actually looks really good and rides much better than with the H&R springs in the front. It sits about .5" higher in the front now.

IMO, the stock setup w/lowering perches is perfect...brings the rake back. Even though I know that to you, it probably looks worse since it's putting slightly too much weight up front. :P

has anyone done this to a LCI e92 or with the bmw performance suspension?

[mattsten]

It should work good on an LCI e92. ASFAIK, there were no changes to the suspension that would make these not work. I am going to be putting new springs on and won't be reusing my set, I will sell them to you cheap if you want. PM me if interested.
