MAZ Muscle Rear R1 Evo Widebody Kit - Carbon Fiber (MAZ-24-WB-REAR-CF) - 2024-2026 Ford Mustang
Transform your 2024-2026 Ford Mustang with the aggressive stance and performance-focused construction of the MAZ Muscle Rear R1 Evo Carbon Fiber Widebody Kit. Inspired by modern GT and Time-Attack race cars, the R1 Evo was developed with an emphasis on stance, airflow management, aerodynamic performance, and clean body integration rather than exposed hardware or cosmetic-only width.
This rear-only configuration retains the Mustang's OEM front appearance while dramatically widening the rear of the S650. Constructed from carbon fiber, the kit combines lightweight composite body components with a significantly wider rear profile, CFD-developed aerodynamic surfaces, and a flush-mounted, rivet-free design for a clean performance-oriented appearance.
Rear-Only Widebody Configuration
The Rear R1 Evo Widebody Kit is designed for Mustang owners who want to retain the factory-style front profile while creating a dramatically wider rear track and body appearance. Dedicated rocker panel and side skirt components provide the transition from the OEM-width front of the vehicle into the widened rear bodywork.
MAZ Muscle specifies that the rear-only system adds approximately 2.5 inches of width per side at the rear. Separate manufacturer information describes the total rear-width increase as 5.5 inches, so those supplied measurements should be verified if an exact overall-width specification is required.
Carbon Fiber Construction
This version of the R1 Evo Rear Widebody Kit features carbon fiber construction throughout the included widebody components. The composite construction provides a lightweight, performance-focused alternative to the fiberglass versions while adding the premium exposed carbon fiber appearance suited to high-end street, show, and track-oriented Mustang builds.
Race-Inspired R1 Evo Design
Inspired by modern GT and Time-Attack race cars, the R1 Evo uses performance-focused surfacing and aerodynamic geometry rather than relying solely on added body width for visual impact. The result is a widebody package designed to give the S650 Mustang a significantly more aggressive stance while maintaining clean transitions and cohesive body lines.
CFD-Developed Aerodynamics
MAZ Muscle states that the major aerodynamic surfaces of the R1 Evo Widebody Kit were refined using CFD analysis. The design process focused on improving cooling efficiency, airflow management, and aerodynamic balance at speed, giving the widebody system functional performance objectives in addition to its aggressive appearance.
Flush-Mounted, Rivet-Free Installation
Rather than using exposed rivets or visible mounting hardware as part of the styling, the R1 Evo is designed around a flush-mounted installation. This creates cleaner transitions between the factory body and widened carbon fiber components while maintaining an OEM-inspired finished appearance.
Included Components
- Carbon fiber rocker panel and side skirt components for the OEM-front-to-wide-rear transition
- Add-on carbon fiber wide rear quarter panel - left side
- Add-on carbon fiber wide rear quarter panel - right side
- Carbon fiber rear bumper widebody attachment
Professional Installation Recommended
The R1 Evo is a multi-piece aftermarket widebody system that requires integration with the Mustang's existing bodywork. Professional installation and body preparation are recommended. The complete kit should be test fitted and properly aligned before permanent installation or other final finishing.
