Cusco RS 1-Way Differential Lotus Elise 04-05

Designed to provide maximum traction that is most often lost in hard off-the-line acceleration, these L.S.D. kits are designed to integrate with your factory transmission. The unit will sense when one wheel starts losing traction due to track/road conditions, hard cornering, and/or torque steer. Once it detects the slippage, it will compensate by shuffling the power from side to side to overcome the loss of traction. This translates into better track or quarter mile times, and more efficient use of the engine's power.
