Porsche has selected Multimatic’s DSSV dampers for the 2021 992-based 911 GT3 Cup racing car. The DSSV is a popular damper in motorsport, used by many race teams, including Formula E, GT and sportscar racing, many single-seater formulae and grass-roots racing, as well as 40% of the 2021 Formula 1 grid.
Every new Porsche 911 GT3 Cup race car competing in the Porsche Mobil 1 Supercup and numerous national Carrera Cups will be fitted with DSSV technology. The high-fidelity hydraulic damping uses precision spool-valve technology that Multimatic says gives predictability, accuracy and repeatability. The frequency response of the spool valve provides “outstanding” transient characteristics, while its turbulent flow regime minimises temperature effects and the basic architecture of the damper eliminates cavitation, enabling low charge pressures.
The 911 drivers will be in good company, as Red Bull Racing took all of its Formula 1 World Championship victories using Multimatic dampers, while the Ford GT won the 2016 24 Hours of Le Mans on DSSVs and the Porsche 919 Hybrid Evo fitted with DSSVs smashed the Nürburgring Nordschleife lap record. The Mazda RT24-P will soon return to the notoriously bumpy Sebring Raceway, where in 2020, its DSSVs helped the car to ride the bumps all the way to overall victory in the 12-hour race.
Raj Nair, Multimatic‘s president & COO said, “Multimatic continues to develop our unique damper technologies and we’ve always believed that there’s no better proving ground than motorsports. Within motorsports it’s well known that the Porsche Carrera Cup is the premier one-make race series in the world and we’re happy to see the series expand to North America.”
