The Alfa Romeo Giulia Quadrifoglio is already ticking all the boxes one expects from a super sedan – a Ferrari-inspired 375kW/600Nm twin-turbo 2.9-litre V6 engine, 8-speed automatic gearbox, 50:50 weight distribution, active locking differential and extendable carbon fiber aero-splitters. Now, enthusiasts can tighten up the handling of their Giulia Quadrifoglio even more with a set of sport lowering springs from chassis specialist KW Automotive.
The ST high-performance springs from KW are made of chrome-silicon steel alloy which enable a lowering of 20 mm on both axles, giving the sportiest sedan from Alfa Romeo a lift in driving dynamics and a sporty appearance.
According to KW, the minimal pitch and roll movements of the Quadrifoglio is further reduced by the ST springs and the sedan responds even more direct to steering movements, heightening sporty driving feel. When developing the springs, the KW automotive engineers decided on a progressive spring, which is claimed to harmonise perfectly with the Alfa Romeo’s standard active dampers.
For the spring design, KW engineers decided to use mini block springs, also known as barrel springs and form springs, as they are shorter in the spring-loaded state than linear racing springs. coupled with the progressive springs the setup has the advantage deflecting harder at stronger stimulations, thus everyday comfort is not compromised.
