Subaru’s in-house performance tuning division is preparing a fantastic looking WRX STI sedan that’s parked at the 2011 SEMA Auto Show.

Aesthetically speaking, Subaru Performance Tuning’s imprint is all over the car as evidenced by all the aerodynamic additions given to the sedan. The front lip spoiler, the carbon fiber B-pillar trim, the carbon fiber trunk trim, and the carbon fiber side sill plates are all products of SPT. The WRX STI also carries new strut tower and lower chassis braces that come in handy in maximizing the potential of the car’s newly-installed Cusco Zero-2E coilover suspension kit.

Other exterior additions to the car include a moon roof air deflector, exhaust finishers, a billet oil cap (V.2), a billet battery hold down (V.2), and a set of 19" Volks Racing G12 wheels wrapped in Yokohama ADVAN Sport tires with Brembo’s "Gran Turismo" four-wheel brake kit.

Inside, SPT gave the WRX STI a unique electronic set-up, highlighted by a Footwell illumination kit, an auto-dimming mirror with a trans-reflective display, and a media hub digital music integration system with a 10" KICKER subwoofer.[...]
