[GR86] Rear Under Diffuser 2022+

Give the rear of your GR86 a wider, lower, and significantly more aggressive appearance with the TOM’S Rear Diffuser.

Designed specifically for the 2022+ Toyota GR86 ZN8, this diffuser enhances the factory rear bumper with a sharper, more performance-focused design while maintaining the clean integration expected from TOM’S.

The diffuser extends approximately 15 mm beyond the factory body line and sits approximately 27 mm lower, creating a more planted stance and giving the rear of the GR86 a stronger motorsport-inspired presence.

It is also designed to complement other TOM’S aerodynamic and exhaust components, making it an ideal upgrade for a complete TOM’S GR86 build.
