I know there's alot of thread about the dreambeams etc. so please excuse me for making another one

The time has (finally) come that I can start working on my bump properly(So this is the start of my endless HELP threads

The plan is to get a set of DJM Dreambeams and do a flip kit and/or relocate the hangers.
I want my truck to be as low as possible without sacrificing driveability with negative camber etc. I'm hoping around a 4" front drop and 5" rear if possible.
So I was wondering, 1- With the dreambeams is it best to use a set of original style new springs or to cut a coil or two off of my old ones? Like I said I want it to be low as possible without creating bad camber. Or can I purchase some lowering springs? If so is there any point?
2- What is the go with shockers? Should I purchase a set of the DJM supplied ones?
3- What is the best possible way to lower the rear without doing a C-notch and having enough distance between diff and frame..
The reason I can't do a C-notch is in Aus you needa go through hell and back to get it all engineered in order to register it.
Oh yeah and I have flexo-matic springs..
The truck won't be carrying and loads, occasionaly maybe a 200kg motorbike but that's about it.
Thanks heaps for any and all help!
