Rally Armor MF32-UR-BLK/BL-X UR Mud Flaps Blue Logo for 15-21 WRX/STI Sedan

Vehicle Fitment

• 2015-2021 Subaru WRX - Sedan Only (VA Chassis; All Trims)
• 2015-2021 Subaru WRX STI - Sedan Only (VA Chassis; All Trims)

Fitment Notes

• Sedan body style only. The 2015-2021 VA-chassis WRX and WRX STI were available in both sedan and 5-door hatchback body styles. The MF32 kit is engineered and bracket-fitted for the sedan's specific rear quarter panel and fender liner geometry. It is not compatible with the hatchback/5-door body style - a separate Rally Armor part number is required for the hatchback.
• This kit covers the full VA-chassis production run of both the WRX (2015-2021) and WRX STI (2015-2021). It is not compatible with the 2022+ VB-chassis WRX, which uses the MF92-UR series.
• No drilling is required. The kit uses precision-engineered stainless steel brackets that mount to existing factory body panel attachment points using the supplied hardware.
• Sold as a complete set of four flaps - two front and two rear - covering all four corners of the vehicle.
• The -X suffix on this part number designates the Altered Font logo variant. The flap body, fitment, construction, and protection are identical to the standard MF32-UR-BLK/BL (no -X suffix). The only difference is the typeface used for the Rally Armor wordmark printed or molded on the face of each flap.

Features

• 3D scanned precision fitment for the VA WRX/STI sedan - Rally Armor developed the MF32 fitment using 3D scanning of the 2015+ WRX/STI sedan body structure, resulting in bracket geometry and flap contours that conform accurately to the specific curves of the VA sedan's fender liners and lower body panels; this precision fit ensures that the flaps sit correctly at all four corners without gaps, misalignment, or contact with rotating components
• Premium UR-series polyurethane construction - the UR compound delivers a combination of impact resistance, flexibility, and long-term dimensional stability that rubber and vinyl mud flaps cannot match; the material absorbs the repeated high-energy stone and gravel impacts that mud flaps are exposed to without cracking, gouging, or permanently deforming; in extreme cold where rubber becomes brittle and prone to cracking at the edges and mounting holes, the polyurethane formulation maintains its flexibility and structural integrity; in high temperatures where vinyl softens and develops a permanent downward curl that reduces the flap's coverage area, the UR compound holds its correct shape
• UV-resistant compound - UV inhibitors in the polyurethane formulation prevent the material degradation, surface chalking, and discoloration that cause rubber and vinyl mud flaps to look worn and aged well before the end of their service life; the UV resistance allows the black surface and blue logo to maintain their appearance in all climates
• Abrasion-resistant surface - the polyurethane compound resists surface scoring and wear from continuous gravel and stone impact; the front flaps in particular receive sustained abrasion from road debris thrown directly against them by the front tires at high speed; the UR compound's abrasion resistance means the flaps continue to protect the vehicle's bodywork without their own surfaces deteriorating into thin, holed, or pitted material
• Altered Font logo design - the -X variant features a stylized version of the Rally Armor wordmark with a modified typeface compared to the standard font used on the base MF32-UR-BLK/BL; the Altered Font provides a visually distinct appearance for owners who prefer the alternate logo aesthetic
• Direct fit with no drilling - all four flaps mount using stainless steel brackets and hardware that attach to factory-threaded locations and existing push-nut attachment points on the VA WRX/STI sedan body; no holes are drilled in the fender liner, rocker panel, or body structure; the installation is fully reversible
• Stainless steel mounting brackets - the brackets resist corrosion from the road salt, brine, and moisture exposure that undercarriage mounting hardware experiences in year-round driving and winter conditions; corrosion-free brackets ensure the flaps remain securely mounted throughout their service life without seized or degraded fasteners
• Comprehensive four-corner protection - the full set of four flaps intercepts the tire-generated spray, road stones, gravel, mud, salt, and tar at all four wheel positions; the rear flaps provide particularly important protection to the lower rear quarter panels on the WRX/STI sedan, which are directly in the path of spray thrown rearward by the rear tires during wet-weather driving
• ISO 9001:2015 certified manufacturing - Rally Armor holds ISO 9001:2015 OEM supplier certification, confirming that design, production, and inspection processes meet international quality management standards

Product Description

The Rally Armor MF32-UR-BLK/BL-X is a complete set of four black UR-series polyurethane mud flaps with blue Altered Font logo, engineered specifically for the 2015-2021 Subaru WRX and WRX STI sedan (VA chassis). The MF32 fitment was developed using 3D scanning of the VA sedan body structure, producing bracket geometry and flap profiles that conform precisely to the factory fender liner and lower body panel contours at all four corners. This precision engineering eliminates the gaps, misalignment, and imprecise coverage that often result from universal or near-fit mud flap sets adapted from other applications.

The UR-series polyurethane compound combines impact resistance, flexibility, and shape stability across a wider temperature range than rubber or vinyl alternatives. The material resists cracking in extreme cold where rubber becomes brittle and prone to splitting at mounting holes and edges, and holds its shape in high heat where vinyl develops a permanent downward curl that reduces coverage area and eventually causes the flap to drag on the ground. UV inhibitors in the compound prevent the surface degradation and fading that cause rubber and vinyl flaps to look worn within a few seasons of sun exposure. The abrasion-resistant surface withstands the continuous high-energy stone and gravel impact that mud flaps endure without developing holes, thin spots, or surface scoring that would compromise their protective function.

Installation requires no drilling - all four flaps use stainless steel brackets that attach to existing factory body mounting points using the supplied hardware, keeping the modification fully reversible. The -X suffix identifies this as the Altered Font variant, featuring a stylized Rally Armor wordmark typeface on the flap face; fitment, construction, and protection are identical to the standard MF32-UR-BLK/BL. This kit is sedan-specific - owners of the WRX or WRX STI hatchback/5-door body style require a separate Rally Armor part number.
