C5 Z06 T1 - Spec

Up for sale is a 2003 Corvette Z06 (C5Z) built to T1 spec / Spec Corvette, with just over 28k miles. This car is fully caged and comes with its official SCCA T1 racing logbooks, making it eligible and proven for wheel-to-wheel competition. We’ve owned the car since 2022 and have continually improved it with professional upgrades, including a custom header-back race exhaust with emissions delete and ECU tune, suspension and bushing refresh, brake and cooling system enhancements, and a full professional wrap by Evolve Graphics (2023). It also features an AIM MXm digital GPS lap timer/data system that automatically detects the track and records laps down to the thousandth of a second. Unlike most track builds, this car comes with receipts and detailed records for all work ever done, including dates and prices, plus a full maintenance log.
