coming back after many months - need advice on handing/suspension

Hey all,



I bought a 2012 135i n55 early this year. Since then, ive done a lot with BMS tuning, including:



- intake

- chargepipe

- downpipe

- jb4

- intercooler



And the car does have a lot of power, esp when it hits 18 psi. But, i remember that many on the forum mentioned that the car won't feel fast until you mod the suspension. Also, the mechanices who installed these parts suggested "struts and sways".



I would like to upgrade the suspension or whatever it is to make the car feel better in turns and more confidence-inspiring. Right now, going around a roundabout feels kinda clumsy and not precise or sharp. The handling is not really that great on the 135i. It feels unstable and I don't feel in control. Anyone know what I'm talking about? What things can I do to fix it?



Specific part/kit recommendations would help. What about the BMW performance suspension kit?



Thanks!
