FAQs
A rear bumper diffuser lip is an aerodynamic styling component installed on the lower rear bumper of the Toyota Supra A90/A91 MK5. It enhances the car’s aggressive rear-end appearance and creates a more performance-oriented OEM+ motorsport look.
Yes, the HONGHANG rear bumper diffuser lip is specifically designed for Toyota Supra A90/A91 MK5 models from 2019–2023, ensuring OEM-style fitment and seamless integration with the factory rear bumper structure.
Installing a rear diffuser lip provides several advantages:
Enhances aggressive sports car styling
Creates a lower and wider rear visual stance
Adds OEM+ performance-inspired appearance
Complements front lips and side skirts for full body kit styling

PP (polypropylene)
ABS plastic
Carbon fiber style materials (depending on version)
These materials provide:
Lightweight construction
Strong impact resistance
UV and weather protection
Long-lasting durability for daily driving use
Common finish options include:
Gloss Black → sporty OEM+ look
Matte Black → stealth performance styling
Carbon Fiber Style → aggressive motorsport appearance
These finishes help match other Supra exterior and aerodynamic upgrade parts.

Screws or bolts for secure mounting
Automotive-grade 3M adhesive tape for reinforcement
Minor drilling in some cases depending on design
Installation usually takes 30–90 minutes depending on experience level.

Speed bumps
Driveway ramps
Curbs and uneven roads
This is a common trade-off for achieving a more aggressive and sporty appearance.
No. When installed correctly using proper mounting methods and alignment, the rear diffuser will not damage the original bumper or paint. Proper installation ensures OEM-style fitment and long-term durability.

Front bumper lips
Side skirts
Rear trunk spoilers
