F30 340 xdrive modded suspension questions

kleitos77 · 09-25-2021, 07:47 PM

Recently bought a 2016 BMW 340i xdrive from Carvana. Great price ($31k all in) and similar mileage. Noticed the car has been modified and/or wrapped at some point. Car has the MPPSK kit installed along with tune (no sticker but the HP/torque is there 380-390 on both), sport transmission, and every additional factory package MINUS m-sport. Grab bag of modifications. SO on to my question...

The car has been lowered on what appear to be H&R springs along with m-sport struts. My question is if this is an alright configuration or if I need to invest in coilovers in the future? Thanks! Attached is rear springs picture and front struts with P/N

right now..."if it ain't broke, don't fix it"

if there comes a point in time where you feel the dampers are failing or not performing properly, then replacing them with Koni Yellow sport or Bilstein B8 may be considered. if you'd rather switch to a coilover, consider KW V1 or Bilstein B14 PSS if you rather spend less and don't mind a firmer ride.

Thanks for the suggestion, Im just happy to have scored such a good deal. I will have to look up what rims/offsets/tire sizes work with those and go from there. Thanks!
