According to ConsumerGuide, the "regular coupes and sedans got suspension revisions to improve ride and handling, as well as additional sound insulation."

Questions:

1. What exactly was changed in the suspension?

2. What kind of additional sound insulation did the 2002 model have?

 

Well, they're referring to the Civic Si, which in '02 was a hatchback. You know, the EP3. There's a rather large amount of differences in between the Coupe and the Hatch.

 

no, they're referring to regular coupes and sedans, which it specifically states.

All I can seem to find on it. Woohoo, a new steering pump.
