Show original supplier description
The STI Rear Spoiler Wing is a high-performance exterior upgrade crafted from dry carbon fiber for exceptional lightness and rigidity. The spoiler itself is made of dry carbon fiber, complemented by durable forged aluminum stays. This wing offers 2-way adjustability, allowing for fine-tuning of its aerodynamic properties. This component is not merely an aftermarket addition; it comes as standard equipment on the STI complete car, specifically the Subaru WRX S4 tS NBR Challenge model. Subtle yet distinctive, the STI logo is engraved on both the left and right sides of the wing tip plates, signifying its performance heritage. Compatibility is specifically listed for Subaru WRX S4 VAG models from Applied A (08/2014-05/2015) through Applied G (08/2020-03/2021) with the FA20 engine, and Subaru WRX STi VAB models from Applied A (08/2014-05/2015) through Applied F (06/2019-04/2020) with the EJ20 engine. Installation requires the Subaru OEM Torsion Bar Set (RH: 57521VV020, LH: 57521VV030) for all grades. Additionally, all grades, with the exception of the VAB Large Wing Spec, will require the Subaru OEM Weather Strip (57532VA002). It is important to note that compatibility information is provided by the maker for JDM cars only, and fitment is not guaranteed. Buyers are advised to conduct their own research before purchase, as after-sale support does not include installation assistance.
