Yes. The diffuser fins expand the exiting underbody airflow, reducing rear turbulence and drag while adding stability at speed. The benefit increases with vehicle velocity and is most noticeable on track above 60 mph.
Will this diffuser fit my exhaust system?This diffuser is designed around the factory exhaust exit positions for the 2015-2020 Ford GT350. Most OEM-location cat-back systems are compatible. If your exhaust uses relocated tips or custom exit positioning, verify clearance during test-fit before final installation.
Does installation require cutting or drilling?No. The AC-RL15MU350 uses the OEM rear attachment points. No new holes or body modification are required. A test-fit before final fastening is recommended to confirm all exhaust and body clearances.
Will this affect factory tow hooks and jacking points?Yes, access to factory jacking and tow hook locations is preserved in the design. If you have aftermarket underbody accessories, verify clearance during test-fit before committing.
How does carbon fiber hold up to road debris?The marine-grade gel coat with UV inhibitors resists UV degradation and light surface scratches. Like any composite bumper cover, direct high-speed rock impacts can cause chips. Carbon fiber panels will not rust, dent, or permanently deform. Minor surface damage is repairable with carbon fiber repair kits.
Can this diffuser be painted?Yes. Prep with a flexible composite primer and apply automotive basecoat and 2K clear coat for a color-matched result alongside adjacent painted panels.
Does Anderson Composites warranty the rear diffuser?Yes. A limited manufacturer warranty covers material and workmanship defects. Road debris impact damage, improper installation, and ground-clearance-related damage are excluded. Contact Anderson Composites for full terms and claim procedures.
How long does installation take?Rear diffuser installation typically takes one to two hours. The vehicle needs to be safely lifted for undercarriage access, the OEM lower valance is removed, and the new diffuser is secured using factory clips and fasteners.
