About S-01

S-01 is BARBARO’s most ambitious street formula — designed to deliver both everyday civility and track-day capability. No compromise, no excuses.

42 months of development (3.5 years): 25 months of dyno testing, 21 months of real-world long-term testing, 4 months of internal testing across 20 vehicles, followed by 4 months of public beta testing across 120 vehicles (1,000+ km each). This level of validation is almost unheard of in the industry.

S-01 excels in noise control across diverse platforms, delivers controllable high-speed braking, and after the 3,000 km break-in period, produces less dust than C-01. On race cars, it performs exceptionally well when installed on rear axles.
