Show original supplier description
The Mntriderdesign 2008-2014 Subaru STI Hatchback Wide Body Kit is engineered to give your vehicle a more aggressive stance and improved aerodynamic profile. Constructed from MntRider Design's proprietary fiberglass and polymer weave, this material mimics the strength and lightweight properties of carbon fiber without the premium price tag. This kit is not only about aesthetics but also aims to enhance aerodynamic performance. This comprehensive kit includes all necessary components to significantly alter your Subaru's appearance and capability: two front bumper flares, two front fender flares, two rear door flares, two rear fender flares, and two rear bumper flares. The primary benefit is the ability to accommodate significantly wider wheel and tire setups, allowing for approximately 3.5 to 4 inches of additional width compared to stock. Specifically, it facilitates the use of wheels as wide as 18 x 11 with a +6 offset, paired with tires up to 295/30R18 or even wider. It is important to note that some vehicle modifications, such as changing the front bumper to a more current year, may be necessary to achieve optimal fitment. For detailed guidance, it is recommended to refer to the product images or contact MntRider Design directly. Professional installation is mandatory for this wide body kit to ensure proper fitment and performance.
