The N1 Evolution is the newest generation of A'PEXi's 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, A'PEXi gathers incredible amounts of suspension data from their direct involvement in many different racing series. This specialized data goes directly into their sports parts development to provide the customer with the same cutting edge suspension technology they use on all of their race vehicles. Within the last few years, the phenomenon known as "drifting" has taken over the US by storm. In Japan, they've been battling it out with the worlds top drifters for years in the pinnacle of professional drifting competitions, the D1 Grand Prix. Suspension setup is key to provide the proper balance and stable handling characteristics suitable for drifting. Using the D1 GP to fine tune their suspension setup, they were able to create the ultimate drifting coilover. The result was a first place win.
