Motorsports has always played a crucial role at Callaway. The marque possesses a legendary record at many of the world’s great race tracks: Spa, Suzuka, Paul Ricard, Nürburgring Nordschleife and GP courses, Monza, Vallelunga, Hockeheim, Daytona, Lime Rock, Road Atlanta, Sears Point, Laguna Seca, Charlotte, Texas World Speedway, Watkins Glen and Mugello.

Callaway’s motorsports venture was created in 1985 under the name “Wöhr & Ciccone”. Since its founding, the Leingarten, Germany company has specialized on body production and race car construction. In 1988, company business expanded to include distribution of Callaway Corvettes in Europe. Callaway Competition GmbH got its name in 1994. Since then, racing Corvettes developed and built in Leingarten for ADAC GT Masters and other series have achieved great success. Callaway Competition is the oldest team in ADAC GT Masters, and started in 1993 with a Corvette C4 at the ADAC GT Cup. Since 2006, more than twenty GT3 Corvettes have been built in Leingarten.

Currently, Callaway Competition campaigns its own GT3 race team and sells Corvette GT3 race cars and support parts and equipment to leading race teams throughout Europe. GM has expanded Callaway’s exclusive authorization to homologate, construct and sell Corvette GT3 race cars worldwide, including North America.

Development of the Callaway Corvette C7 GT3-R began in mid-2014 on CAD, under the supervision of Ernst Wöhr and Giovanni Ciccone, with technically-relevant parts designed by Mike Gramke and Uwe Hoffmann. The first Callaway Corvette C7 GT3-R’s set new standards in the ADAC GT Masters series.

The body and dashboard were CAD-designed by Paul Deutschman, Callaway’s designer of over 30 years, of Deutschman Design – Montreal, Canada. By the end of 2014, vehicle design was established and, in the spring of 2015, prototype construction commenced at Callaway’s German facility.

Callaway Competition supplied dimensional data for specialist suppliers who milled forms for body parts. The carbon fiber parts from these forms were chiefly manufactured in Leingarten, with some produced by friendly firms.

The only stock components retained from the Corvette C7 are the chassis, which is reinforced with the roll cage, the lower control arms, the upper half of the rear bumper and the tail lights. The naturally aspirated 6.2-liter engine was carried over from the Callaway Corvette Z06.R GT3 with minor changes. Other parts were newly developed and manufactured, with the major part of the technical components from aluminum and carbon fiber hand-built in Leingarten.

The front spoiler, diffuser and rear wing aerodynamic components were developed and implemented in CAD by Paul Schreiber and Alex Koppe. The shape and the profile of the rear wing corresponds to all the latest developments in aerodynamics.

Callaway Competition partners Ernst Wöhr and Giovanni Ciccone utilized all their race car building experience in the construction of the Corvette C7 GT3-R.

The greatest moment in the history of Callaway’s LM GT cars…

Crossing the finish line at Le Mans 1995.

During the last lap, Frank Jelinski, behind the wheel of Car No. 73, waited for Rocky Agusta in Car No. 004 so the two Callaways could cross the finish line together.

Callaways finished P2 and P3 in GT2, P9 and P12 overall.

Race Car Fabrication Services

Fabrication Services

Artful fabrication is a key part of presenting a mechanical design. At Callaway, we’re versed in all the traditional fabrication arts and recognized for the handsome execution of our designs both above and under the hood. While we’re employing advanced fabrication techniques at our California and Connecticut facilities, we are building world-class, champion GT race cars at Callaway Competition. Constructing these machines requires forming, cutting, machining, welding with a wide variety of metals. Callaway Competition’s expertise in carbon fiber and other composite materials also allows them to produce lightweight, strong structural components and body panels. Traditional German craftsmanship combined with innovative, state-of-the-art technologies results in clever, efficient fabrication solutions.

The Callaway Corvette C7 GT3-R, one of the most powerful, successful and reliable GT race cars, is built by Callaway Competition GmbH in Leingarten, Germany. There is no factory support in building racing Corvettes for GT3 competition, so each detail is developed by the Callaway Competition team, directed by General Manager, Ernst Wöhr. It all starts with a completely-stock Corvette C7 road car. After removing all of the interior and stripping the car down to the bare aluminum chassis, the car gets its steel roll cage. Since the FIA steel roll cage cannot be welded to the Corvette’s aluminum frame, the roll cage is bolted and bonded to the chassis on steel supports. Hundreds of man-hours are spent converting the world-class road car into a world-class GT racer. Most of the carbon fiber parts on the car are hand-made at Callaway Competition to ensure the best possible product quality.
