For E46 chassis with N52 engines (2005-2006 330i, 330ci, 330d), this BLA1693-4L set replaces the front and rear rubber lines with TÜV-certified stainless steel braided hoses - no flaring, no adapters, no guesswork.
Fitment exact: Designed for E46s with standard ABS and non-M sport brakes - not for M3 (E46) or Z4 (E85/E86)
Stage 1 & fast road ready: Firmer pedal, reduced fade on spirited drives - no change to ABS calibration or brake bias
Track day compatible: DOT-compliant, pressure tested to 3,000 psi - but not a full race-spec upgrade (no AN fittings or custom routing)
