TL;DR: Werk83 diecast models in this collection cover 1970s Porsche endurance racing specials and Group 5 silhouette racers in 1:18 scale. A single-manufacturer, single-marque range concentrated on one of motorsport's most visually extreme regulatory eras, when flared bodywork turned road cars into near-unrecognizable competitors.
Group 5 regulations asked for a silhouette resemblance to a road car and little else, and Porsche's response pushed flared arches, massive rear wings, and turbocharged power to genuinely dramatic extremes.
Group 5's Flared Bodywork and Silhouette Racing Rules
Werk83's 1:18 builds concentrate on the flared wheel arches and oversized aero that defined this regulatory era, details that have to look aggressive rather than restrained.
- Flared arch width and rear wing scale specific to Group 5 regulations.
- Livery and sponsor decal accuracy on period silhouette racing entries.
- Proportional contrast between the road-car base and the racing bodywork added.
Endurance Racing Specials Alongside the Silhouette Cars
The endurance racing specials included here offer a more conventional counterpoint to the Group 5 extremes, showing that Porsche's 1970s competition program wasn't only about outrageous silhouettes.
