Celebration and disappointment -- that's what the Subaru Impreza WRX STI 20th Anniversary edition brings to the party. Celebration because it marks two decades of low-mounted, boxer-powered, all-wheel-drive fun and disappointment because the Takumi concept we saw earlier this month – assumed to be a glimpse of the future Spec-C WRX – was just an early unveiling of this limited edition Impreza.

To make matters worse, the 20th Anniversary WRX doesn't get much in the way of modifications. The only substantive changes to the STI's dynamics come from a new set of coilovers with retuned springs and shocks to offer a more planted ride, along with thicker front and rear anti-roll bars and a set of 18-inch aluminum wheels to compliment the only available hue (white). Body mods are also kept to a minimum, with only a black lip spoiler and rear wing subtly proclaiming the STI's special status.

No special edition would be complete without the prerequisite badging, so in addition to leather Recaros with red stitching and a matching shift knob, a commemorative plaque on the center console and a new set of door sills are the only thing letting people know that the Impreza is one of the 300 limited edition examples. Oh, and there's a special red pouch for the key fob too.

Sales are beginning in Japan as you read this, carrying a price tag of 4,126,500 yen.
