Cusco Street A, 40-Way Adjustable Twin-Tube Coilover
The Cusco Street A is a street-focused coilover system that brings genuine damper adjustability to everyday driving. Built on a twin-tube design and individually developed for each vehicle application, the Street A offers 40-step damper adjustment across the full front and rear, making it one of the most tunable options in its class without requiring a track-oriented setup. It is available in two variants — the Street A Blue tuned for comfort and mild lowering, and the Street A Red tuned for a sportier character with a wider use range including autocross and open track. Both are manufactured in Japan in ISO 9001 and ASEA certified facilities and feature Nickel-Chrome treated damper cases for long-term corrosion resistance.
