Manthey’s take on the 992-generation GT3 RS adds aggressive carbon-fibre aero including a massive wing with endplates, roof vanes, a supported front splitter, canards, rear-wheel aero discs, shark fin and an enlarged diffuser. The package increases downforce from 860 kg at 175 mph on the standard 3RS to more than one metric tonne without an added drag penalty.
Underneath, Bilstein dampers are replaced by KW units with custom springs and valving, now integrated into Porsche’s PASM system for in-cabin adjustment. The car also gains braided brake lines and Michelin Pilot Cup 2 R tyres. The Manthey option costs £99,999 and can be selected through Porsche’s configurator.
