Here are things I did in this order on my 2011 F53 chassis. First installed Saf-T Steer stabilizer which stopped the constant corrections on the steering wheel to keep her in the lane. Second the CHF on the rear stabilizer bar. Big improvement on eliminating the body roll (for example when a semi passes). Finally, a front end alignment which addressed almost completely any undesirable effects during driving. No Trac Bars, no airbags, no Sumo Springs, no Koni shocks. Just the above.
That's it, and the F53 now handles like a dream.
