I have an 07 328i non sport base model. I have no suspension mods but swapped out the 16s and put on the 17s from an 09 335 (225/45 R17, style 284, square setup). Im def considering the M3 Strut Bar and was wondering if I will need anything else for the suspension upgrade being that I only have the base suspension.
Or is it simply a matter of bolting it on and start driving?
Is this all I need? Also, do you have any installation guides for this?
