Show original supplier description
The Cusco LSD 428 L2 is a limited-slip differential designed to significantly enhance a vehicle's driving dynamics, especially for those participating in motorsports. Unlike open differentials that can send power to a spinning wheel, this advanced system ensures that power is consistently transferred to both driving wheels as needed, maximizing traction and control. This is particularly beneficial in high-performance driving scenarios where grip is paramount. Key features of the LSD 428 L2 include its 1.5-way (also available in 2-way) operation, providing a controlled locking effect that aids in stability during cornering and acceleration. It is engineered with specific ramp angles of 55/20 degrees and 55/55 degrees, and an initial torque setting of 8-10 kg, allowing for precise control over its engagement. The tunability of this differential is a standout feature, enabling drivers to adjust its locking characteristics to match their individual driving style and the demands of various race tracks or rally stages. Whether a rapid lock-up for sharp turns or a smoother response is required, the LSD 428 L2 can be fine-tuned to deliver optimal performance. This particular model, the LSD 428 L2, is listed as compatible with the Mazda MX-5 (NC) NCEC, specifically for models with Manual/Automatic Transmission, an OEM Diff of OPEN/TORQUE SENSING, and model years ranging from 2006-2010 and 2012-2015. Customer feedback highlights noticeable improvements in traction during cornering, leading to a more stable and responsive feel, and enhanced acceleration out of turns.
