▶ Vehicle Fitments
The DBA Front 4000 Series Plain Brake Rotor for the BMW M3 E46 (01-06) is a high-performance replacement component designed to enhance braking efficiency and durability. Constructed from high-quality materials, these rotors feature a plain finish that provides consistent heat dissipation and resistance to warping under demanding driving conditions. The 4000 Series is engineered to deliver improved braking response, reduced fade, and longer service life, making it suitable for both street and track use. Its robust design ensures reliable performance during aggressive driving, while maintaining compatibility with OEM specifications.
This rotor is intended for use on 2001 to 2006 BMW M3 E46 models, but vehicle fitment should be verified through precise measurement of existing brake discs and pads, as fitment may vary depending on the brake package. It is a direct replacement for the original equipment, offering an easy bolt-on installation. The kit includes the rotor itself, with no additional components required. Ideal for enthusiasts seeking a reliable upgrade for daily driving or spirited track days, this rotor provides consistent braking performance and enhanced heat management for the BMW E46 M3.

Notes Regarding Vehicle Compatibility:
Vehicle fitment provided in this listing is to be used as a rough guide only and may not actually suit your vehicle. Due to multiple brake packages sometimes being offered by manufacturers it may be necessary to measure your existing brake discs and/or pads and compare with the measurements provided by DBA here:

DBA's 4000 Series disc brake rotors are a direct replacement single-piece brake rotor, designed for drivers seeking upgraded performance braking in the Specifications tab and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.
Featuring DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).
DBA's 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look, such as under controlled race divisions.
Features (Where Applicable):
Kangaroo Paw 144 diamond and tear drop pillar ventilation system
- Increased surface area resulting in greater heat dissipation which minimises brake fade and increases braking effectiveness and prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs
XG150 High Carbon Alloyed Iron
- An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time which minimises warping and cracking and prolongs the service life of the rotor.
- Special formulation designed to respond to DBA's TSP process.
Thermographic Temperature Monitoring
- Heat paint markings change colour at specific temperature thresholds offers the driver a clear indication of peak braking temperatures.
- When temperature thresholds are exceeded paint markings will permanently change colours allowing the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers with warranty claims.
Paint protection on non-friction areas
- Reduces corrosion, enhances appearance, stops any unsightly rust formation, adds value to the product.
