Yep, base 128i suspension is basically rubbish. Intended to keep pricing low to entice more people into the brand. As Chris flies and I found out, beefier front and rear sway bars make a huge difference, and adding the rear bar is something that should be done with the rear subframe completely lowered. You may be fortunate, being from sunny CA, and not have to re-tap or run a thread chaser into the holes where the sway bar bushing mounts go. Mine were a mess. So were the brake lines. If you decide to go that far, replace the rear subframe bushings with M3 bushings, or urethane. Between the M3 bushings and ECS sway bars (28mm front/15mm rear), I am amazed at the difference. Just the bigger front bar made a huge difference, but understeer was worsened by it until the rear bar went in.
