MX5 NA6 KAAZ 1.5 Way Diff Approx 7-10 day lead time 12 Plates for mild to medium power levels 1.5 way Fits cars equipped with or without factory LSD option Part# DBZ1610 A 1.5-way limited-slip differential is the most common LSD upgrade option in performance and race cars. It is referred to as a 1.5-way because it functions under acceleration and to a lesser extent under deceleration. It provides differential locking characteristics under acceleration, maximizing power distribution to the wheels that need it most. Under deceleration, the 1.5-way LSD engages to assist in braking stability and smoother turn-in.
