On average Eibach Pro Lowering Springs will lower your vehicle 1.2" in the front and 1.0" inches in the rear, providing for a lower center of gravity and improved handling. Pro Springs feature more control than that of the OEM springs, but are still comfortable for daily use. I'll shoot you over a PM with more details!
Your website doesn't show which part number can be used with the xi...can you share those details?
