Transform the way your BMW X3 E83 stops on circuit and fast road. This Paragon front axle braking package delivers serious stopping performance, rock-solid pedal feel and excellent thermal control when driven hard, while remaining civilised for everyday use. It is a direct-fit upgrade for 2003-2010 X3 E83 models and is engineered to work seamlessly with factory systems.

Why it belongs on your X3

• Six-pot PA015 or PA035 aluminium calipers provide strong, even clamp force and crisp modulation. The only difference between PA015 and PA035 is the maximum disc size they accept.
• Two-piece floating brake discs with directional internal vanes move air efficiently for cooler running and consistent performance. Expect temperatures up to thirty percent lower than stock one-piece discs in extended sessions.
• Hard anodised calipers and aluminium hats resist wear and discolouration under repeated heat cycles.
• Piston sizing is tailored for the E83 platform, retaining the factory master cylinder and ABS behaviour for natural brake balance.
• Pairs perfectly with standard rear hardware for a well-matched overall setup.
• Complete bolt-on front axle kit supplied pre-assembled with all components required for a clean, straightforward install.
• Ideal for track days, spirited B-road driving and daily commuting where confidence and repeatability matter.

Real-world confidence

We run Paragon braking hardware on our own builds at MJ Modifications and our customers consistently praise the fierce initial bite, progressive control and fade resistance lap after lap.
