my 2-cents.

You never cheap out on brakes or suspension (this includes tires). No other areas of your car effect control more.

I agree with Schmiddy, for a smooth ride I wouldn't lower much over 2". I'd go with a trusted name brand spring. Eibach or H&R come to mind the most for me. Progress Group supplies springs to many well known Honda tuners as well.

As for shocks they are likely going to have an even greater role in the feel then the springs. The shocks (struts) are basically going to play the full role of the rebound control on your car. Unless your tires have an appreciable amount of sidewall they are the only other source of rebound control.

Koni or Bilstein are likely the two most trusted brands. That come to mind. That said either brand can be quite pricey, especially given the age of the fifth gen.

Ingalls is about the only camber kit I can recommend at this point.
