The Serpent Jubilant (SZ) WSR was a series of high-performance vehicles manufactured by Serpent and modified by WSR. It was based on the SZ Jubilant chassis.
Australian Group A regulations at the time stated that 500 road-going units needed to be built to qualify for homologation, so WSR was contracted by Serpent to modify and produce a racing-oriented road car. As a result, similarly to the previous SK generation, it carried Serpent badges, though it was technically a WSR. Produced by Serpent and modified by WSR between 1987 and 1989, a total of 550 units of the road-going Group A model were built.
The bodywork of the Jubilant SZ was heavily altered to improve aerodynamics and downforce. An entirely new body kit was developed for the car, specifically to minimize air resistance and to maximize airflow. The body kit was made mostly out of plastic and fiberglass. Covered foglights were added to the bumper, and a single-slit grille was fitted to improve engine cooling. It was given widebody arches and a door and sideskirt kit which improved general airflow. Finally, a large rear deck wing was added to assist rear downforce.
The engine was further modified from the SK Group A, mainly focusing on strenghening components while also fitting larger turbochargers which produced a distinct notable fluttering. It uses a 5.9L V8, mated to twin turbochargers and a 5-speed manual transmission. It produces upwards of 320 horsepower, and corners well considering its large size.
WSR produced a total of 550 units of the SZ Group A. The original run of 500 was required and produced in 1987 and 1989, while another 50 were produced into the beginning of 1989 due to popular demand.

This is one of my personal favorite cars I've ever made. I spent a lot of time on it, and I hope you will enjoy it!
Thank you for driving my cars.
