So first impression, the response time between pressing the gas pedal and power to the wheels is so much faster. Actually, Dinan recommended this LSD for RWD 550 to handel the additional power from the mods (stage 4) There is way too much power for standard differential=wheels slippage and then power reduction from traction control under WOT especially in corners. Not an issue with the Xi models. The LSD ensures that all that power gets put to the ground.
