Lean on it through a freeway ramp, though, and the soft factory springs let the body roll and the nose dive under braking. It sits a little tall, too. You want it tighter and lower without turning your daily driver into a buckboard.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Performance Spring Set for the BMW G30 M550i xDrive lowers the car 3\/4 in. front and rear and raises spring stiffness 15% at both ends. The result is less roll, less dive and less squat, sharper turn-in, and a lower stance that closes up the wheel gap.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy the Dinan M550i Spring Set Rides Better Than Typical Lowering Springs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMost lowering springs drop the car and eat suspension travel, which is how you end up bottoming out over dips. Dinan pairs these springs with a Supplemental Ride Quality and Handling Kit (D193-3071) that uses tuned progressive bump stops to keep full travel at the lower height. Choose the \"Yes\" option above to add it. Dinan strongly recommends running both together. Without the kit you will not get the advertised ride height or ride quality, and Dinan will not warranty handling or ride complaints that come from skipping it.\u003c\/p\u003e\n\u003cp\u003eEach spring is CNC wound from high tensile chrome silicon wire and shot-peened for stress relief, so it is built to last the life of the car. Dinan part number D100-0932.
