2002 Chevrolet Corvette Z06 Specter Werkes/Sports GTR
Inspired by the success of Corvette's C5-R racing program, Specter Werkes/Sports created the GTR to bring competition-inspired styling and performance to the street. Believed to be one of just 25 conversions, this 2002 Z06 combines an aggressive widebody design, exclusive craftsmanship, and a Katech-developed 427ci V8, creating a Corvette far beyond the ordinary.
Designed by Specter Werkes/Sports founder Jeff Nowicki in Troy, Michigan, the GTR was built for enthusiasts seeking something more exclusive than a factory Z06. Finished in white with bold red and blue stripes, this example features a distinctive widebody conversion that adds approximately three inches of width up front and six inches at the rear. A vented cowl-induction hood, enlarged fender vents, rocker extensions, detachable front splitter, and rear wing give the car its unmistakable presence. Fixed projector-style headlights, a contrasting black rear panel, and exclusive GTR badging complete the transformation.
Beneath the hood sits the centerpiece of the build, a Katech-developed 427ci C5-R V8. With Katech's established connection to Corvette's endurance racing success, this engine brings an impressive performance pedigree. Featuring Jesel rocker arms, Manley exhaust valves, Johnson tie-bar lifters, and upgraded cooling components, the V8 is paired with long-tube headers and a custom dual exhaust system. A six-speed manual transmission and limited-slip differential keep the driving experience engaging and true to the Z06's performance roots.
The upgrades extend well beyond the engine. Four-way adjustable Feal coilovers with Swift springs, Pfadt adjustable sway bars, and additional suspension refinements give this GTR the hardware to match its aggressive appearance. AP Racing Pro 5000 R calipers paired with Essex two-piece rotors provide serious stopping capability, while silver 19-inch Forgeline GS1R wheels wrapped in Michelin Pilot Sport Cup 2 tires complete the purposeful stance.
Inside, the GTR retains the driver-focused character that made the C5 Z06 so appealing. Black leather high-back bucket seats, a head-up display, dual-zone automatic climate control, and a Bose sound system offer a welcome balance of performance and comfort.
Identified as Specter Werkes/Sports GTR SWS 02-002-20, this rare Z06 offers something few Corvettes can match. With its limited-production heritage, unmistakable widebody styling, and Katech-developed 427ci V8, it represents a unique opportunity for the collector or driving enthusiast seeking a Corvette that truly stands apart from the crowd.
