Anytime you lower a McPherson Front-Front car, you introduce suspension problems at an alarming rate and not necessarily in logical proportion to the suspension changes you've made.

If somebody's lowering an EP3 or DC5, I'll usually go out of the way to caution them to buy at the upper end of the suspension market, from people we know will have well researched all the issues related to Honda McPherson suspension geometry.

The McPherson system is not nearly as resillient as the usual Honda double wishbone suspensions, and it's important, especially if the car's used in any kind of high performance application, that the suspension designer know what he's doing.

Assuming the person buying the suspension is mostly interested in better handling, I'd suggest that a no-brainer like the Mugen SS is a logical choice for both the DC5 and EP3. The Mugen SS is designed to not need a camber kit or any adjustment other than a regular toe-in and thrust angle alignment after installation.
