History

The Spec Boxster series is the largest and most competitive class in Porsche Club racing and typically draws fields of 25-30 cars. The series is limited to first-generation Porsche Boxsters (1997-1999) and requires the use of stock OEM 2.5L engines and stock transmissions. Some upgrades are allowed in suspension and braking systems.

This car’s brake calipers were completely refurbished in January 2022 by PMB Performance in Salt Lake City. The suspension was upgraded to the fully-adjustable Motion Control 1WNR SPB damper system in October 2020. All other parts are easily sourced on the open market.

The Boxster was transformed into a Spec Boxster racer in April 2018 by RennPart Motorsports in Virginia. The car won its first two races out of the box. It was purchased by the current owner in August 2020 and has raced 3,230 miles since then.

 In September ,2021, a rare, zero hour, Porsche factory 2.5L M96 engine was installed by Vortex Motorsports in Tampa. The engine has now raced fewer than 2,000 miles since installation and its performance has been flawless. It produced more than 200HP in a recent dynamometer run (193-195 is typical for Boxster engines).

 Maintenance has been meticulously performed after each race. Fluids are regularly changed. Brake pads are new. Most general maintenance can be performed in a home garage. Exacting records have been kept on all maintenance work, including cost and part sourcing.

 The car has raced at Sebring, Daytona International Speedway, Miami Homestead, Road Atlanta, VIR, Carolina Motorsports, Watkins Glen, COTA, New Orleans, Mosport, Indianapolis Motor Speedway, and Road America. It has victories at VIR, Road Atlanta, Mosport, and Road America and podiums at Sebring, Watkins Glen, and New Orleans. In SCCA, the car has podiums at Daytona, Sebring, and VIR and is competitive against Mustangs, BMWs, and Nissans. It has also competed in The Mitty, Historic Sports Car Racing’s classic weekend at Road Atlanta.

 The Porsche was featured on the April cover of PCA Club Racing Magazine.
