This Ultima GTR was constructed in 2003 and was registered in Illinois prior to its purchase by the current owner in 2013. Its Chevrolet LS3 V8 was acquired from Turn Key Engine Supply of Oceanside, California with an increase in displacement to 7.0 liters and installation of Mahle pistons, a Brian Tooley Racing Stage 2 camshaft, a five-angle valve job, Johnson lifters, H-beam connecting rods, and an LS7-specification dry-sump oil system. Additional features include a recently-rebuilt Porsche G50/52 five-speed manual transaxle, a limited-slip differential, a stainless-steel exhaust system, AP Racing calipers, Braid wheels, adjustable coilover suspension, carbon-fiber aerodynamic aids, and an adjustable rear spoiler as well as a roll cage, dual foam-filled fuel cells, and Sparco racing seats. This Ultima now has 7,300 miles and is offered on dealer consignment in California with a dyno sheet, a specifications list, a spare wheel set, and a clean California title listing the car as a 1974 model year. The fiberglass bodywork is finished in yellow gelcoat and features an adjustable front splitter, custom-fabricated carbon fiber side skirts, front fender louvers, and an adjustable rear wing sourced from APR Performance. Staggered-width 18″ Braid wheels are mounted with Nitto racing tires, and four spare Forgeline wheels fitted with Pirelli P Zero tires will also be included in the sale. The AP Racing braking system features six-piston calipers up front and four-piston units out back, and it includes a cabin-mounted dial to adjust the braking force between the front and rear axles. Additional features are said to include MacG Racing adjustable suspension components and Intrax adjustable dampers. The cockpit features dual Sparco race seats equipped with cam-lock Schroth five-point harnesses. Additional interior equipment includes a roll cage, a carbon fiber/balsa wood laminate floor, a fire extinguisher, a backup camera, a Coolshirt personal cooling system, a helmet-to-helmet intercom system, a GoPro mount, and LED lighting. The MOMO steering wheel is mounted on a quick-release hub and fronts a dashboard panel housing Stewart Warner instrumentation consisting of a 200-mph speedometer and a tachometer, and a suite of digital readings is mounted below. The digital odometer indicates 7,300 miles. The Chevrolet LS3 V8 features a drive-by-wire throttle and was rebuilt to a displacement of 7.0 liters in 2019 and is said to have been used for less than 10 hours since the rebuild, which was performed by Rob’s Auto Machine of Hayward, California.
