About the 2018 WRX STI Type RA (x2):

In 2018 Subaru Tecnica International did the United States a huge favor with a production run of 500 WRX STI Type RA vehicles, each with their own serialized number plate next to the shifter. The new limited-edition Type RA takes the already great STI and makes it much, much better. The Type RA’s name is inspired by the Nürburgring record-attempt car (the "RA" in Type RA).

- Serialized number plates, limited to 500 vehicles
- Adjustable rear carbon wing gives measurable downforce over 50mph
- 310 horsepower at 6000 rpm from a 2.5 turbocharged EJ25
- 290 lb-ft @ 4000 rpm
- Strengthened pistons and sodium-filled exhaust valves
- 19-inch forged BBS wheels
- Carbon fiber roof
- Bilstein STI sport-tuned dampers

The engine gets significant upgrades, including new sodium-filled valves and reinforced pistons. These upgrades are essentially durability upgrades, helping the Type RA to withstand extended high rpm and high-boost track usage. Combined with some electronic tweaks, a larger-diameter exhaust, and a cold-air intake, the STI Type RA's upgraded 2.5-liter engine is rated for 310 hp and 290 lb-ft. Jointed with a 4 percent shorter third gear ratio, (1.590:1 in place of the standard STI's 1.521:1), the Type RA feels perceptibly quicker in typical corner carving, most of which happens at third-gear speeds. The STI Type RA is also 68 pounds lighter than a factory-spec STI equipped with Recaro seats. The weight is mostly cut by dropping the spare wheel/tire kit, but some of the weight savings also comes from the carbon fiber roof. As a result of the weight savings, the Type RA's center of gravity is a few millimeters lower.

Inside, a steering wheel wrapped in microsuede, a red engine-start button, and a serial-number plate are the only cues to this model’s exclusivity. The Subaru’s molded spoiler is replaced for an adjustable high-mount carbon-fiber wing, which makes measurable downforce at speeds of more than 50 mph. A front splitter and new rear bumper that has functional air ducts to reduce drag and lift. There are Cherry Blossom Red accent stripes on the grille up front and on the bumper out back. The RA’s silver-painted, reinforced six-pot Brembo calipers and cross-drilled rotors look perfect behind the 19-inch forged gold BBS wheels. The STI Type RA was available at select U.S. dealers in Crystal Black Silica, World Rally Blue Pearl, or Crystal White Pearl.
