Superformance MKII Slab Side SPS0034

MKII SPS0034 is one of the world’s most beautiful Superformance Street 289 roadsters. From the heritage wire wheels to the burbling Ford V8, this car has the classic cues you want in a British roadster with the reliable power you expect from an American powertrain.

SPS0034 was custom ordered clad in Grigio Silverstone two-stage paint with extra clearcoat; a clear bra was fitted to the nose and fenders to protect the beautiful finish, along with the fender spats and underbody rockers. Like new condition, the roadster has Bullet style mirrors, and authentic rear exit under-car exhaust with ceramic coated headers to maintain the sleek original style appearance. It even wears genuine 2-lug knock-offs splined 15” X 6” Dayton chrome wire wheels with 205/70/R15 tires front and rear; a matching spare is in the trunk.

Original style Sun visors, polished stainless-steel bumpers front and rear, wind wings, and fender side vents help create the picture of 1960s sophistication. Options include a tonneau cover, top, side curtains, and a stainless-steel gas tank.

The Ford 347 cid “stroker” motor makes a healthy 410 horsepower and 418 ft. lbs. of torque. The small block V8 connects to a 5-speed transmission with a hydraulic clutch that sends all the power to a ZF limited-slip IRS differential housing the 3.52:1 final ratio gears. The engine is kept cool by the Harrison expansion tank and HD Aluminum radiator with thermostatic controlled HD electric fan; a manual override is located on the dash.

This Superformance MK II Street 289 stays true to the original John Tojeiro-designed chassis with its 3” tubular rail ladder style main tubes and welded cross-members. The rack & pinion steering helps keep the car pointed faithfully while the fully adjustable front and rear transverse leaf spring style suspension manages bumps in the road. Stopping power is impressive due to the car’s power disc 4-piston Wilwood Brakes with double master cylinders. Ross Henry designed and engineered several upgrades for Superformance that were incorporated into the vehicle. These include Heim joints fitted to the lower control arms, adjustable shocks front and rear, and front and rear sway bars to sharpen the MKII’s handling.

SPS0034 has a classic Moto-Lita hardwood-rimmed steering wheel and period-correct Stewart Warner gauges. Tan leather was fitted throughout the interior, including the seats (on sliders). The convertible has an original style grab handle, heater/defroster controls, and fresh air vents. A side-screen pocket is located behind the seats, and the Superformance car has both door and map pockets.

The Superformance MK II Street 289 is a meticulously engineered and crafted reproduction of the original, built under license from Carroll Shelby Licensing Inc. No expense was spared in recreating the legendary cars, ensuring an authentic sports car experience.

SPS0034 is titled and registered in California under SB-100 with under 4,000 miles and is available
