The 964 Carrera RSR is a triumph of Porsche’s production-based GT racing efforts, blending the performance of the slightly less-potent RS 3.8 with full-scale, race-ready engineering. Built as a Turbo-bodied competition machine, the RSR was designed to dominate both major European GT events and North America’s Supercar series. Its rear-mounted Type M64/04 3.8-liter air-cooled flat-six was an engineering marvel featuring natural aspiration, 11.4:1 compression, lighter pistons, dual ignition, dry-sump lubrication, and Bosch electronic fuel injection. Depending on class regulations, this potent mill was rumored to deliver up to 375 horsepower—or even more—providing breathtaking speed and outstanding drivability.

While the RSR used the standard 964 production shell as a foundation, each chassis was seam-welded for rigidity before being sent to Matter for the installation of a fully triangulated roll cage. Lightweight construction extended throughout the car: alloy doors and front lids, a steel engine cover to support the large fiberglass rear wing, lightweight front and rear bumper facias, thinner side and rear windows, and a front-mounted oil cooler. The suspension was comprehensively upgraded, featuring stainless-steel Heim joints, competition Bilstein dampers, and Turbo S-derived brakes, all stashed behind 18-inch center lock Speedline modular wheels. Tipping the scales at just 2,673 pounds dry, the RSR 3.8 was not only under the FIA minimum weight limit, it was blisteringly fast: capable of 0-60 mph in 3.7 seconds and a top speed exceeding 180 mph.

The celebrated example on offer, chassis 496081, stands out as the most successful RSR of the 1994 season. Ordered through Porsche’s Special Vehicle Department in September 1993, the car was delivered that December to privateer racer Mark Sandridge of Westfield Center, Ohio. A factory invoice confirms the car’s original specification, including open exhaust, center locks wheels, and an air jack system.

Dressed in Grand Prix White and competing under Sandridge’s Team Salad banner, the RSR enjoyed a spectacular 1994 IMSA GT season including 2nd in class and 4th overall at the 24 Hours of Daytona, class wins at both Sebring and Watkins Glen, and ultimately earning Sandridge the IMSA GT2 Championship, 2nd in the Exxon Championship, and 2nd in Class in the World Porsche Cup.

After its banner 1994 season, the RSR found a new home in 1996 with Karl McKeever of Morrow, Georgia, who kept the car on the track and pushed its performance even further. Through upgrades from Porsche Motorsports North America, the RSR received a 3.8-liter engine with slide-valve throttle bodies, reportedly generating over 400 horsepower. With these enhancements, it continued to chase podiums across SCCA and Porsche Club of America events for another decade. In 2006, the car crossed the Atlantic, purchased by UK-based Porsche enthusiast Neil Primrose, drummer of the Scottish rock band Travis, adding another chapter to its remarkable story.

Finished in its iconic 1994 Team Salad livery, this RSR has most recently enjoyed a cherished life of sparing use and remains a remarkably well-preserved example. It is accompanied by significant documentation including a Porsche Manufacturer's Statement of Origin, Porsche Motorsport North America invoices and correspondence, race history, period photographs, as well as select spare parts.

With its ultra-limited production and championship-winning history, this Carrera RSR 3.8 presents a rare chance to own a factory-built, air-cooled racing 911, equally suited for concours display or a glorious return to spirited competitive use.
