Up for auction is this 2019 Ultima Evolution/RS, finished in Brilliant Blue with silver stripes over a black interior, powered by a 426 cubic-inch stroker LS3 V8 running through a Porsche G90 six-speed manual transaxle, with 1,100 miles on the clock.

Dream Cars is pleased to offer this Ultima for auction, an example built for the owner to an exacting specification, as a street legal track-focused sports car perfect for track days.

Ultima, based in England, is a small builder known for their years of experience custom building sports cars. They produce high-quality chassis under the “kit car” classification, which exempts them from meeting government regulations that large-scale manufacturers must abide by. They are designed to accommodate Chevy’s popular LS and LT motors, allowing a wide range of power levels to choose from, and comprehensive support for tuning and custom specification, which this owner took full advantage of.

The Ultima Evolution RS is the latest model by the company, and represents decades of development and experience building dedicated sports/GT cars for capable drivers. The owner of this car ordered it from scratch, and had an informed and specific idea of what he wanted from his track car build, and selected everything himself down to the smallest detail.

The result is an impressive specification for the experienced track aficionado. with carefully selected options and equipment for enjoyable, reliable track days, while providing the proper pace and capability to challenge the driver. This is fully analog drivers car, with no traction or braking aids, which is something mass production manufacturers simply aren’t allowed to do.

Though registered as a 2019, full completion of the build occurred in 2020.

During the build of this car, Ultima announced a new RS spec of the Ultima, with upgraded mechanical and cosmetic specs. The owner promptly requested that every RS upgrade be included in his build, thus making it an Ultima/RS. A three-ring binder detailing all the specs of the build is available, and will come with the sale. This is an excellent, fully optimized example with no stories, and has never been driven in rain or inclement weather - garage kept its entire life, and ready to go for its next owner.

The roof scoop for the engine induction is extended to the front, and all engine air ducts and louvers are constructed of carbon fiber. The front splitter, canards, and rear spoiler are all carbon-fiber, and adjustable.

All gauges and switches are fully operational.

This Ultima/RS is powered by a naturally aspirated, 426 cubic-inch LS3 V8, with a dry-sump oiling system.

It was built to customer specification by Mast Motorsports out of Nacogdoches, Texas, a highly respected engine builder that specializes in Chevrolet LS and LT motor builds. It started with a new LS3 block, then built from the bottom up - forged internals, aluminum heads, race fasteners - resulting in a light and powerful stroker LS3 motor that was dyno-tested at 550 hp to the wheels, for reliable naturally aspirated horsepower.

The engine runs through a new Porsche G90 six-speed transaxle, aided by a CAE short shifter kit, chosen for its size and stout construction. Brakes are power assisted, AP Racing six-piston calipers at all four corners with slotted rotors, covered by 19" three-piece Forgeline modular wheels, with Michelin Pilot Sport Cup 2 tires in 265/30-19 size in front, and 325/30-19 out back. The Ultima does not have any electronic driver aids or anti-lock brakes, and the hydraulic steering is not power assisted.

The remote reservoir shocks are fully adjustable for compression and rebound with upgraded springs running at 600f/700r lb/in, while the sway bars are upgraded from stock spec to Ultima’s race spec.

Curb weight of this Ultima is estimated to be 2,050 pounds, dry weight.
