WP Pro Front 350x28mm 2pc Brake Rotor Upgrade BMW M3 E46

We have a used set of WP Pro 2pc brake rotors for the BMW M3 E46 with the CSL brakes. This set was used for 1 track day. Rotors are in good working condition and show minor stress. Great to use for the street. Can order new discs and hardware if needed later on. This is a steal for a pair of rotors.

The BMW E46 M3 is one of the most iconic M cars to date which has become extremely popular for track enthusiasts.  One of the most important upgrades for the car is the brakes.  Most E46 M3 enthusiasts go with the CSL upgrade which includes an entire new brake bracket assembly to run the larger rotors.  Many companies make a CSL upgrade option, but only have a 1 piece or semi floating 2 piece rotor.  The WP Pro brake rotors upgrade you from a 325x28mm to a 348x28mm that is a full 2 piece fully floating design with 32 vanes for the best braking possible.  This front brake upgrade is a direct fit for those that already have the CSL upgraded brakes.  Better braking means you can go faster into the turns, which gives you faster lap times to be ahead of your competition. 

To improve your braking, you want to have better heat dissipation, even brake pad wear, and a firmer pedal feel.  One of the biggest advantages of doing a brake upgrade is the rotational weight savings.  The factory brake rotors weigh 19.1lbs.  The solid disc surface lacks the performance of light weight 2 piece rotors.  The WP Pro rotor weighs only 16.9 lbs which saves you 2.2 lbs per corner over stock.  Rotational weight savings has an estimated factor of three.  This is like taking 6.6 lbs of dead weight off each corner!  The WP Pro rotors feature a unique Sun Cut pattern with the drilled holes. Because the rotor features rotational drilled holes and more effective curved vanes, it helps dissipate heat away from the rotors.  This design is used to improve cooling by pushing cool air from the center of the wheel to where the rotor needs it most.  It also acts like a heat exchanger to carry heat away from the rotor.  With the 2 piece rotor design and the improved cooling, the brakes pads have an even wear on both sides and almost no brake fade. 

Each kit has been manufactured with high quality control standards and has gone through rigorous testing.  The kit features anodized machined aluminum hats and 2 piece floating hardware.  Each kit is sold as a pair of complete rotors.  Replacement brake discs can be sold when necessary as the brake hat is not a consumable item.

Weight Savings:

  • Stock Rotor - 8.66KG
  • WP Pro Rotor - 7.66KG


  • Anodized rotor hats
  • Full floating assemblies with stainless steel M8 bolts vs standard M6 hardware
  • Directional vented, heat treated, and coated rotors 


  • Requires CSL upgraded brake brackets

Vehicle Engine Notes

WP Pro Brakes has been in business since 1981 with facilities in Canada, Taiwan, and the UK producing high quality OEM and aftermarket braking systems. It does everything from forging, machining, assembly, and even race car testing. This is not just another colored chinese caliper kit, there is engineering behind the WP Pro components. Proving this point is their Race/Track brake systems. The specific calipers share the same body as their beautiful EX6 6piston caliper but with titanium vented pistons, 3D machining on the body, for where looks are secondary, and performance is the main focus. The 6-piston race caliper weighs just 2.6kg and is designed strictly for racing. These WP Pro racing kits were developed for the WTCC and Asia Carrera Cup racing series. Having partnered with the Chevrolet Cruze WTCC teams, their 4 piston calipers are the same design as the EX6 and include anti-knock-back springs, titanium piston covers with stainless steel pistons, and a structural bridge. These calipers were tested against some major companies' calipers and proved stronger and more rigid.

What we are really excited about is its Carbon Ceramic rotor offerings. For years it has been only the OEMs who had the carbon ceramic rotors as a factory options. This option could cost upwards of $30,000 and good luck finding cheap or any replacement parts. The reason carbon ceramic rotors are so highly desired is they are EXTREMELY lightweight and simply do not fade. WP Pro Brakes has a huge application list of Carbon Ceramic rotors for almost every high performance car including Aston Martin, Ferrari, Nissan GT-R, Porsche 996 997 Turbo or GT3, and others. Of course these are not or never will be priced as low as standard steel discs, but are much more affordable and for those looking at serious braking performance or upgrades, this is an amazing option. For some of the Carbon Ceramic kits, WP Pro offers the discs to work with the factory hat, or alternatively will include the hat assembly and pads. Some kits are even a Plus 1 size to give you more rotor surface for better braking. For price comparison, the front 997 Turbo carbon ceramic rotors to work with the OEM 6piston calipers are $7800. That is in the OEM size of 380x35 but they even do a 'Plus 1' kit to a 392x35mm!

Now that we have shown they have the track record to back up their products, we can tell you that WP Pro Brakes also carries an entire line of street/track big brake kits. Every make model you can think of from Audi A4, BMW M3, Mini Cooper, Corvette, Ferrari, Mercedes and the new CLA, Ford Focus ST and Fiesta ST, Infiniti, Lamborghini, Lexus, Mazda, Nissan including GT-R, Range Rover, Porsche, Scion including FR-S, Volkswagen, and more. Each big brake kit includes 2 piece rotors, steel braided brake lines, calipers, pads, lightweight brackets and hardware to install. Where available, a Plus 1 rotor size can be had and some kits are available in 4, 6, and 12 piston calipers. Their EX6 6piston caliper as pictured below features an optional carbon fiber vent duct as well. All replacement parts are available for each kit if needed.
