The fronts are a bit of a pain in the ass because you have to remove the covers right underneath the windshield to get at the suspension top struts.
Although actually that's still fairly easy. There's a significant change in the rear suspension, not the least is that the spring and damper are now separate entities rather than the "coil on damper" crap in the old Civic. It takes a bit more time, but still not that difficult- you can install everything on a weekend if you've got all your tools handy.
