You have an E90, not an E92. The M-Tech or M-Sport kit for the E90 is also known as the BMW M-Aerodynamic kit and available at your local dealership as an accessory. I'm not sure where DFW is.
The M-Tech front bumper and rear bumpers for the E90 are complete bumpers. The front bumper includes a set of new foglights that is shaped differently and uses different bulbs (9006). It also comes with an additional plastic undercarriage that extends the existing one. Also included with the kit are side skirts. The rear bumper comes with a detachable diffuser and plastic insert that goes between.
