Front and Rear Brake Lines

The GruppeM Brake Line System is a high-performance brake hose upgrade featuring a Teflon inner core reinforced with a stainless steel mesh coating. By minimizing hose expansion under heavy braking, this system ensures that pedal input is transmitted directly to the calipers without loss, providing a more consistent and firm pedal feel compared to standard rubber hoses. The exterior of the hose is encased in a protective PVC coating, shielding it from external damage, heat, and environmental factors. This construction offers superior pressure resistance, making it suitable for both street driving and circuit use. This kit is a vehicle-inspection compliant product that has passed rigorous testing specified in JIS D2601. This specific kit, part number BH-3054S, is designed for the 2010-2014 BMW 3 Series (325i) with the N53B30A engine, covering chassis codes E90, E91, E92, and E93. It includes both front and rear lines for a complete vehicle-wide upgrade.
