Toyota GR86 Rear Diffuser Kit – Genuine OEM (PJ158-18800-XX)
This rear diffuser kit gives the GR86 a more aggressive, performance-inspired finish by refining the lower rear bumper area. It adds visual depth and definition to the rear end, helping the car look wider and more planted without overpowering the factory design. Designed as a GR aero upgrade, the diffuser follows the GR86 body lines closely and ties in cleanly with other GR exterior pieces. Available in multiple color options, it allows the rear styling to be tailored while keeping the overall look cohesive and intentional.
