"The N1 Evolution is the newest generation of our track engineered flag ship N1 suspension. All N1 dampers feature large piston, monotube design using a threaded base for height adjustments without compromising shock or spring travel. Every year, we gather incredible amounts of suspension data from our direct involvement in many different racing series. This specialized data goes directly into our sports parts development to provide the customer with the same cutting edge suspension technology we use on all of our race vehicles." - A'PEXi USA
