1963 Superformance Slab Side 5 Speed Manual 2-Door Convertible

Superformance is proud to announce the availability of our newest model the Superformance MKII Slab Side – designed to emulate the great Cobra 289 street cars from that nostalgic golden era of racing in the 1960s. Unlike most competitors. the MKII Slab Side is built on the successful Tojeiro-styled round tube chassis and features an authentic transverse leaf spring suspension to give owners an exceptionally authentic driving experience. Through our exclusive agreement with Carroll Shelby. the MKII Slab Side is the latest licensed Shelby product in the Superformance lineup. The Chassis The Chassis is the original John Tojero designed 3” tubular rail ladder with cross-member. This chassis is reproduced using drawings obtained from AC cars and also implements the necessary changes to utilize rack and pinion steering . The 3” tubes are tig and mig welded to guarantee a safer and stronger chassis. This is much stronger than the arc and gas welded originals. Pain staking efforts were made to reproduce the chassis as close to original as possible while incorporating a few modern improvements. Building the cars with a meticulous eye on authenticity took time. but in the end. we feel that effort pays off in a superior driving experience for our customers. The Suspension To compliment an original chassis you need to follow the same rules when it comes to the suspension. It had to be period correct. or as close to it as possible. While the original used a transverse leaf spring style suspension. that arrangement requires different length springs to change camber settings. Because of that. the decision was made to go with heim joints. just like some of the original competition cars used. In fact. two options are offered here – The first being rose joints and the second being adjustable rod ends with poly bushings for a slightly less harsh ride. Another change with regards to safety was to add an additional pick-up point to the chassis to increase the shear strength of the bolt passing through the lower control arm rose joint or poly-bushed rod end. The original springs were made of thinner steel than that available today. In an effort to keep compression rate the same. this car comes with one blade less and “free camber” was changed to keep the ride heights equal from front to rear. This insistence on authenticity means that owners of a Superformance MKII roadster will have virtually the same driving experience as the original . The Body The Superformance MKII roadster bodywork replicates the later of the 289`s which incorporated modifications to fender flares that will accommodate the slightly wider tires fitted onto chrome wire wheels. One of the improvements made by Hi tech was that the footwells were tweaked so that the taller North Americans can now sit comfortably. There are pedals made for short. medium and long legs. Side fender airvents are also fitted. The Interior Again. attention to small details like the replication of the glove box knob and the correct use of gauges make this car stand out from the others. A Side screen pocket is fitted behind the seats on the rear bulkhead and door map pockets are also incorporated in the doors. Lush carpeting finishes off the cabin for a comfortable feel on the road. The Powertrains Fitted with A Southern Automotive date coded 289 with 360 hp and a four speed top-loader.
