Apparently the 2012 coupe and sedan have considerable more body roll that the 2011's. This could very well be due the fact that Honda has engineered the 9th gen suspension to be geared towards luxury rather than sport handling.
If you compare the listed suspension between the two year cars, the only noticeable difference is the thickness of the front sway bars. 2011 has 23mm and 2012 has 18mm bars.
I wonder if I replaced the front bar with an after market 23mm (or perhaps 25mm) would it adversely affect over/under steering. Has anyone had any experience with this kind of mod?
