BMW Brakes & Brake Parts for BMW 3 Series E46 (1999-2005)

The ultimate upgrade when it comes to improving stopping power!

Complete with stunning, British-engineered six-piston calipers and all the hardware you need to completely replace all equivalent components of the front axle of your vehicle’s stock braking system, these complete kits give a firmer and more responsive brake pedal feel and allow you to drive much longer without the onset of brake fade.

EBC Racing Brake Kits come with fully‐floating 2‐piece rotors as standard. These rotors allow the cast iron rotor ring to float independently of the hub, preventing disc cracking and leading to reliable performance even when subjected to the most demanding driving conditions.

This kit comes with everything you need in the box and a detailed vehicle-specific installation pack, including race-spec brake fluid for the final system bleed.

Key Features:

Apollo-Series 6-Piston Calipers

Two-piece bolted design that incorporates high-tensile 12.9-grade steel bolts for reinforcement of the caliper bridge section (computer FEA analysis shows that this offers significant improvements in caliper stiffness compared to a monobloc design) Machined from heat-treated low-pressure castings (this offers a noticeable performance advantage over conventional gravity cast calipers, exhibiting higher overall strength and a comparable caliper body stiffness to forging) High-temperature fluid seals coupled with full boot-type dust seals give maximum protection against road grime and debris Lightweight, hard-anodized aluminium staggered pistons with serrated/castellated piston noses that reduce heat transfer into the braking hydraulics Every single brake caliper pressure tested to 2,500psi Uses standard pad shapes, giving choice when selecting brake pads Fully-Floating Two-Piece Discs

Fully-floating 355x32mm two-piece discs that allow the outer ring to expand freely in response to heat (this reduces stress which in turn extends disc life and reduces the tendency for disc cracking during extreme use) Drive bobbins machined from a single piece of stainless steel giving maximum strength and corrosion resistance (this reduces maintenance requirements and ensures the outer ring continues to float freely over time) Disc rings feature 48 directional internal curved vanes for improved cooling Unique ‘Swept Groove’ slot design for effective evacuation of braking dust and gases whilst ensuring good initial bite on brake application Now featuring the latest thermic black corrosion-resistant finish – the very latest in rust prevention Bluestuff™ NDX Performance Brake Pads

Now road legal in most markets, Bluestuff™ NDX combines excellent cold bite with the capability to perform well in short spells of track/race conditions Stainless Steel Braided Brake Lines

Every hose has a stainless-steel braided exterior that prevents a phenomenon known as ‘ballooning’, this braided exterior prevents the spongey feel of OE rubber lines and provides greater precision and feel under braking Super DOT 4 Brake Fluid

Every kit is supplied with 1 litre of BF307+ super DOT 4 brake fluid. This fluid has a 310°C boiling point – a significantly higher boiling point than standard DOT 5.1 fluid Having such a high boiling point gives the braking system exceptional endurance, allowing you to push hard for extended periods without heat soak causing the fluid to boil and resulting in fade

BMW E46 M3 Semi-Floating Front Brake Rotors - Pair (325x28) are an excellent upgrade for any US spec E46 M3, providing superior braking performance and reliability. Designed as a direct replacement for the factory rotors, these vented 325x28 rotors feature directionally veined construction for optimal cooling efficiency.

Constructed with Zimmermann Formula-Z 2-piece technology, these rotors are lighter than stock alternatives, allowing for improved thermal expansion and contraction, which significantly reduces the risk of warping at high temperatures. The cross-drilled design enhances heat dissipation, resulting in better braking performance and reduced fade during demanding driving conditions.

ECS Tuning offers a wide range of premium brake components, including pads, rotors, shoes, drums, hardware, hoses, lines, fluids, and high-temperature lubricants, ensuring everything needed for a professional brake service is readily available.
