To keep costs down, the concept was to race without making any major modifications, these being perceived as only distorting the technical merits of the original car. For an inclusive sum of 146m Lire (compared 80m for a standard car), customers were provided with a brand new SZ equipped with special Tuning and Safety upgrade packs. The Tuning Kit comprised special shock absorbers, springs and a competition braking system, re-mapped engine management, a racing exhaust and reinforced clutch. As a result, output was probably closer to 250bhp and possibly beyond. The Safety Kit included a roll-cage, four-point racing harness, a fire extinguisher system and tow hook. Additionally, each SZ Trophy car was sold with 12 five-spoke OZ Racing wheels, enough tyres for all eight races and a mechanic at each event too.
