Subaru Press Release:
2010 Subaru WRX STI by SPT
The drivetrain in the WRX STI by SPT is essentially stock, which means a 2.5 liter DOHC, 16 valve,
turbocharged and intercooled 4-cylinder Subaru Boxer® engine with Dual Active Valve Control System. Backed by a 6-speed close ratio manual transmission, it gets power to the road via Symmetrical All-Wheel Drive with Driver Controlled Center Differential (DCCD), limited slip helical front differential and TORSEN® rear differential.
The engine remains stock, including 14.7 PSI max. boost. An SPT exhaust system boosts horsepower to 315 hp @ 6,000 RPM (up from the stock 305), while peak torque remains stock at 290 lb.-ft. @ 4,000 RPM. There is also an SPT turbo heat shield.
For that extra dose of style under the hood, the car features an SPT billet oil cap v2.0 and SPT billet battery hold down v2.0; an STI front lip spoiler and SPT exhaust finishers complete the look.
The stock WRX STI is already a master of the curves; the WRX STI by SPT ups the handling ante with readily available accessories: 19 x 8.5-in. Prodrive® GT2 wheels are finished in Glitter Gold and wear Michelin Pilot Sport A/S 245/35R19 performance tires. Suspension is tweaked with STI performance springs, an SPT strut tower brace and an SPT lower chassis brace.
Interior appointments and electronics are geared to what the average enthusiast can afford and use. So, you won't find half a dozen 10-inch LCDs scattered around the interior. An SPT boost gauge, a media hub digital music integration system and an auto-dimming mirror with transflective display and HomeLink® transmitter, are all available from the SPT catalog. Final touches include an STI shift knob and all-weather floor mats (because Subaru drivers aren't afraid of the weather.)
