Lowering the body reduces the center of gravity and cuts body roll, which improves handling and chassis balance while closing up the fender gap for an aggressive but still driveway-friendly stance. This is H\u0026amp;R's RWD Sport Spring application for the G82 M4 \/ M4 Competition coupe, built for cars equipped with the factory Adaptive Suspension.\u003c\/p\u003e\n\u003cp\u003eH\u0026amp;R's own current fitment data for this same part number also extends coverage to the 2026+ G87 M2 CS on cars equipped with factory Adaptive Suspension — both are RWD-only platforms, so a single H\u0026amp;R Sport Spring application covers them.\u003c\/p\u003e\n\u003cp\u003eSpring rates are progressive and run 10–20% higher than stock, so the car keeps its ride quality in normal driving and firms up for proper chassis composure when the road turns. Every H\u0026amp;R spring is crafted from 54SiCr6 spring steel and shot-peened, which H\u0026amp;R states increases spring life by more than 200% and keeps the springs from settling or sagging. All production is completed in-house at H\u0026amp;R's ISO 9001-certified facility in Germany, and each spring is 100% tested before it leaves the plant. Quality assurance is backed by TÜV and ISO 9001 certification.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eH\u0026amp;R's Sport line for this application lowers the car a similar amount to other G8x Sport kits — approximately 1.0\"–1.3\" front and 0.4\"–1.2\" rear;
