Real-world feedback from MJ Modifications customers

We have installed this kit on customer BMW E46 models and the reactions are consistently positive. Expect a calmer, less crashy ride on rough surfaces, better body control at motorway speeds, sharper turn-in and confident cornering. The rebound adjuster is a genuine game-changer - soften it for commuting and long journeys or add a few clicks for weekend blasts and larger wheel and tyre setups.
