335xi front only lowering?

I have been reading on here for a bit and haven't found an answer to my exact question. I have an 07 335xi e90 and I don't want to lower the back at all, just the front so it is even/slightly lower then The back



I have read that subframe bushing inserts raise the back very slightly so I am planning on that, but I'm unsure what to do about the front. I would like to do Koni fsd shocks all around eventually. figure this should work with the front lowered to around non awd height.



Also going to run e36 m3 bump stops for more travel in the front.



Only option I have seen for just the font is lowering perches, anyone use these or know where to get them?



Are there rubber isolation dampers on the front shocks I could just take out to lower it .5" or so?



Anyone sell front springs only? Don't want the ride much harsher (went to far with my old audi s4) I don't think any kits leave back at stock ride height and lower the front, everyone I have read about still has the awd rake.



Not looking to go coil overs due to expense, any other options you can think of?



I suppose I could run the calculations on how much it would raise the wheel rate to cut a coil off, but it usually is too much stiffer...



Anyway thank you I a advance for any help!
