The IX MR retained the features of the Evolution VIII MR, like Bilstein shocks, a 6-speed manual transmission, a rooftop vortex generator, BBS forged wheels, HID xenon headlights, foglights, accessory gauge package, "zero lift" kit, special badging and an aluminum roof. All models continued to sport Recaro bucket seats, Brembo brakes and Momo steering wheels as well. Additional revisions from 2005 included a closer gear ratio for the 5-speed manual transmission, new lighter Enkei wheels on non-MR models, a redesigned front end with a more efficient air dam (the most noticeable feature are the two small oval ducts to cool the intercooler pipes), and a new rear bumper with a diffuser undersurface to smooth out the airflow coming out of the car for non-US models. HID headlights were no longer standard equipment on the base IX (nor were they standard on the 2005 VIII), and were available only in the SSL package (Sun, Sound, and Leather), SE (Special Edition) and MR trims.
