MAZ Muscle Rear R1 Evo Widebody Kit - Fiberglass with Carbon Fiber Side Skirts (MAZ-24-WB-REAR-PCF) - 2024-2026 Ford Mustang
Give your 2024-2026 Ford Mustang an aggressive race-inspired rear stance with the MAZ Muscle Rear R1 Evo Widebody Kit with Carbon Fiber Side Skirts. 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. The fiberglass widebody components are paired with carbon fiber side skirts for an additional performance-focused visual accent and a distinctive transition from the factory-width front bodywork into the widened rear quarters.
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.
Fiberglass Widebody with Carbon Fiber Side Skirts
This R1 Evo configuration combines fiberglass widebody components with carbon fiber side skirts. The fiberglass construction provides a versatile foundation for professional body preparation, paint, and finishing, while the carbon fiber side skirts add an exposed composite accent along the lower body.
The carbon fiber side skirts also form part of the transition between the Mustang's factory-width front bodywork and widened rear quarters, helping create a cohesive profile from front to rear.
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 approach creates cleaner transitions between the factory body and widened components while maintaining an OEM-inspired finished appearance.
Included Components
- Rocker panel and carbon fiber side skirt components for the OEM-front-to-wide-rear transition
- Add-on fiberglass wide rear quarter panel - left side
- Add-on fiberglass wide rear quarter panel - right side
- Fiberglass 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, paint, or other final finishing.
