Obviously cutting your springs so that you have one coil left.

Ksport makes some good springs. I personally love my h and r race springs with bilstien shocks and struts setup it rides nice and it handles like a dream and drops it a decent amount not to much not to little I'm on 17s and I'm barely tucked. So 18s will be tucked for sure. I'm also running camber caster kit front, camber kit rear via adjustable control arms, TMS sways front and rear with adjustable end links, and racing dynamics strut bar. oh and meyle zhp control arms front with replaceable ball joints with powerflex fcabs.

Well you first need to decide on what spring rates to run. Linear is unquestionably best, and most people like Swift springs. I run 90 kg/cm front and 105 kg/cm rear on my M3 because they were recommended to me by professional race car tuners for the E46 chassis and because I agree with their assessment

Then you'll need some dampers from a reputable company. Ohlins, Moton, AST, and MCS all come to mind. You pretty much can't go wrong with anything from those brands.

Because you will be going lower and changing suspension geometry you will need to change the front upper damper mount and the rear trailing arms to maintain proper geometry. I use ground control for the front mounts (camber plates). It would be best to call them on the phone and tell them what you want so they can piece together your camber plates so they fit with your dampers. Turner Motorsport makes some great rear trailing arms.

Never cut springs. Do it right and get a coil-over kit.

I NEED front upper damper mounts and rear trailing arms if i'm lowering my car on springs?

No but your alignment will be all wonky toy get adjustable camber caster plates for the front so you can adjust camber and caster in the front, and adjustable lower control arms rear so you can adjust camber in rear
