     The BMW 7-Series is widely regarded as the epitome of luxury, appropiately making the statement (for the driver), "i've made it." The 740iL, though not the flagship vehicle, offers unparalleled smoothness and list of amenities that takes a manual the thickness of an encyclopedia to encompass. Aaron Liao's modified DINAN7 screams, "i've arrived...and then some."

Dinan CAI      Aaron has supplemented the BMW's already-potent 4.4l V8 engine with the entire Dinan line of products, making the car worthy of the "DINAN7" badge it wears. The increased air induction via the Dinan cold air intake and air flow meter required an increase in breathability on the output end as well, so on went an Eisenmann High Performance exhaust system terminating in four 83mm pipes which peek out just enough from a Hamann rear apron to make a statement - and make a statement it does as the tarmac rumbles on wide open throttle. To complement the rear apron, Aaron has also installed Hamann's front spoiler and painted everything artik silber to match. When asked why Aaron chose to go with BMW's factory "sport" sideskirts instead of the Hamann pieces which were also available, Aaron replied, "because the Hamann skirts looked too ricey."

Yoko AVS 295      To finish things off on the BPU end, Aaron installed a 3.15 differential from the 740i Sport as a temporary replacement for the stock 2.82 differential while a 3.64LSD is being researched. With the additional power the modifications provided, Aaron needed a better way to put it all down as the stock 16" wheels were neither aggressive nor ample for the ~250rwhp and ~260lb-ft torque the car was producing (at the rear wheels). Aaron swapped on a set of OEM BMW 19" wheels from the 745Li (yes, the one with the chubby rear). Matching the staggered set of multi-spoke wheels is a set of Yokohama AVS Sport rolling stock with a beefy 295mm contact patch in the rear and a staggered 255mm up front.

Lighting      As Aaron's bimmer came from the factory without OEM high intensity discharge headlamps, a Catz 4500k HID kit was retrofitted in and a set of 5th generation Daylight Demon Eyes (similar to the "angel eyes" on 5-Series cars) was installed, giving the front headlights an updated look. Hooked on the xenon glow and in need of a matching (at least in terms of light output) look for his foglamps, Aaron went straight for a Catz 6000k HID foglight kit, passing up the simple bulb modifications that most people do and going straight for a ballast+ignitor setup with the Catz kit. Needless to say, driving through Aaron's favorite mountain pass in the dark is now quite a different experience.

Rear      To avoid possible altercations with the law with the newfound power of his 7er (which can now sprint from 0-60mph in just under 6 ticks of the second hand and run the quarter mile in the low 14s with a trap speed of over 100mph), Aaron has equipped the cockpit of his bimmer with some of the finest countermeasures available. These include a Valentine 1 radar detector and a Uniden BCT-12 police scanner, both hardwired to the vehicle's electrical system so that no unsightly wires show. In addition to this, Aaron wired up a CB Radio (set to monitor channel 19) and an Escort ZR3 laser jammer, which just so happens to be illegal in his native state of California. Finishing up the interior touches are a custom-wired push button starter from the BMW Z8, an M5 sport steering wheel and an AC Schnitzer aluminum pedal set.

     Future plans for the Hamann DINAN7 include a 3.64 limited slip differential with 35% lockup which will effectively bring the car into mid 5-second 0-60mph range and allow it to run through the quarter mile in the 13-second range. A complete custom Alpine/JL Audio/MB Quart sound system is also in the works.
