The Ultimate Guide to Building a Porsche 911 RSR Replica

The 1973 Porsche 911 Carrera RSR is a legend. Born for the track, its aggressive stance, wide arches, and iconic ducktail spoiler have captivated enthusiasts for decades. While owning an original RSR is a dream for most, building a high-quality RSR replica is an attainable goal that offers the thrill of classic racing aesthetics combined with personalized performance. This guide will walk you through the essential steps of a Porsche 911 RSR conversion, from sourcing the right body panels to achieving the perfect stance.

The Heart of the RSR Look: Bodywork and Aero

The RSR's soul lies in its dominant, track-ready appearance. Achieving this look requires a focus on key body panels and aerodynamic components that define its character.

1. RSR Front Bumper and Spoiler

The RSR's front end is arguably its most recognizable feature. The deep front spoiler and integrated oil cooler opening are not just for looks; they provide essential downforce and cooling for high-performance driving. When choosing a front bumper, look for a high-quality fiberglass or carbon fiber replica that matches the original's dimensions.

At Bexco Automotive, we offer a range of RSR-style front bumpers designed for a perfect fit on classic 911 models. Our 911 RSR Front Bumper is a popular choice for its authentic look and durable construction.

2. Widebody Fenders and Flares

To accommodate wider wheels and tires, the RSR was given its signature widebody look. This is achieved through bolt-on fender flares or complete widebody fenders. For a true RSR conversion, you'll need to significantly widen both the front and rear of your 911.

• Front Fenders: Look for 9-inch or 11-inch front fenders to achieve the classic RSR stance.
• Rear Flares: 11-inch or wider rear flares are essential for the aggressive, track-ready look.

Our 911 Turbo Front Fender Flares and 911 Turbo Rear Flares are perfect for your RSR widebody conversion, providing the necessary clearance for wider wheels and tires.

3. The Iconic Ducktail and IROC-Style Wings

While the 2.7 RS is famous for its ducktail spoiler, the RSR took aerodynamics a step further with a larger, more aggressive wing. For a period-correct RSR build, you have a few options:

• Ducktail Spoiler: For a 2.7 RS look, the ducktail is a classic choice. Our 911RS Duck Tail is a high-quality replica that will give your 911 that iconic RS style.
• IROC/RSR Wing: For the full race car aesthetic, an IROC-style wing is a must. These larger wings provide more downforce and are a hallmark of the RSR's track-focused design. Check out our 911 IROC Whale Tail for an authentic race-inspired look.

4. Wheels and Tires: The Foundation of Your Stance

No RSR replica is complete without the right set of wheels. The classic choice is a set of deep-dish Fuchs-style wheels, which perfectly complement the widebody look. For an authentic RSR build, you'll want to go with a staggered setup:

• Front Wheels: 15x9 or 16x9 Fuchs-style wheels
• Rear Wheels: 15x11 or 16x11 Fuchs-style wheels

At Bexco Automotive, we offer a wide selection of Fuchs-style wheels in various sizes to help you achieve the perfect stance for your RSR replica. Our 911 Carrera 2.7/3.0/3.2 wheels are a popular choice for RSR builds.

5. Suspension and Brakes: Performance to Match the Look

An RSR isn't just about looks; it's about performance. To handle the wider wheels and tires and provide the sharp handling a race car deserves, you'll need to upgrade your suspension. Coilovers are a popular choice for their adjustability, allowing you to fine-tune the ride height and damping to your liking.

Brake upgrades are also essential, especially if you plan on increasing engine power. Larger calipers and rotors from a later model 911 or an aftermarket big brake kit will provide the stopping power you need.

6. Interior: Stripped-Down and Purpose-Built

The interior of an RSR is all business. To save weight and create a track-focused cockpit, you'll want to remove unnecessary components like the rear seats, sound deadening, and radio. Here are some key interior modifications for your RSR replica:

• Seats: Lightweight bucket seats, like our Lollipop Racing Seats, will hold you firmly in place during spirited driving.
• Door Panels: Simple, lightweight door panels, like our 911 Race Doors, are a must for any RSR build.
• Roll Cage: For a true track car, a roll cage is essential for safety and chassis rigidity.

Conclusion: Your RSR Dream Build Awaits

Building a Porsche 911 RSR replica is a rewarding project that allows you to create a personalized tribute to one of the most iconic race cars of all time. From the widebody fenders and RSR bumpers to the deep-dish Fuchs wheels and stripped-down interior, every element of an RSR build contributes to its legendary status.
