I took delivery of my 2013 Accord EX-L with Navi in late July. I am coming from a 2009 BMW 3 series which unfortunately was totaled in an accident. I decided to get the Accord for all the reasons why it is such a good seller. I basically liked the car except for its light feel and and some body roll. After reading threads on this forum, I decided to order the 22mm anti-roll bar from Progress Technology. I had it installed by a local mechanic and unfortunately, I do not like it. It has reduced body roll but it has made the ride very harsh! I can feel every bump in the road and the rear end feels somewhat unstable. I will try living with it for a few more days and I will probably put the stock bar back on. This will require drilling out the holes on the ends of the stock bar to accommodate the larger bolts that came with the Progress bar. I do not know if I can return the bar to Progress; I guess that I learned a lesson from this, the engineers knew what they were doing when they designed the components for the car. If I wanted a car that handled like a BMW, I should have bought another BMW.
