Paragon 2-Piece Rear Rotors + Winmax Pads for BMW M3 / 1M Coupe
When a spirited back-road drive turns into a track day, factory rotors and pads reach their limit together — this package upgrades both in one order. This package pairs Paragon's 2-piece floating rear rotors with a Winmax compound matched to how you actually drive the car.
Built for BMW M3 / 1M Coupe owners who want factory-level refinement with real track capability in reserve, whether that's a weekend canyon run or a dedicated lapping day. Choose your rotor hat finish, then pick the pad compound that matches how hard you're actually driving it. Already have pads you're happy with? Select "No Pads" and just get the rotors.
-
Rotor Hat Finish: Black Hard Anodized
-
Pad Compound: No Pads, P2 Street, P3 Sport, R5 Med Temp Track, or R7 Hi Temp Track
- 2-piece floating rotor design reduces unsprung weight and resists heat soak under repeated heavy braking

Paragon 2-piece Rotors (Rear Pair) for BMW M3 (E90/E92/E93) / 1M Coupe (E82)
Upgrade your BMW's braking power with our Performance OE Replacement Rotors! These rear pair rotors, measuring 350mm x 24mm, are designed specifically for BMW M3 (E90/E92/E93) and 1M Coupe (E82) models. Experience enhanced performance and control on the road. Take your driving to the next level with these bold, risk-taking rotors.
Made of CM-250 special formulated high carbon alloy cast iron, it allows for an optimal bite, thermal characteristics, high-temperature strength and durability. Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration then turned by state-of-the-art CBN surface machining to ensure better break-in with new brake pads.
Vibration is reduced as the rotor lateral run-out is kept within 0.03mm and well-balanced: variations are kept within 2 grams. All rotors went through rigorous quality control procedures and inspections to ensure the rotors are fit for their purposes. A slotted rotor improves braking consistency by maintaining a clean contact surface and dissipate heat generated and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface.
Center hats are CNC machined from steel for high strength and durability under extreme conditions, then anodized to increase resistance to wear and corrosion. Allow the use of OEM e-brake.

Best For: BMW Drivers Who Value Sharp Response and Repeatable Braking
These rotors are well matched to BMW applications where steering precision and brake feel are part of the driving experience. They suit daily-driven performance cars, mountain-road use, and occasional HPDE events where repeatable response matters more than flashy claims.
FAQ
Are these complete rotors or replacement rings?
This listing is for a complete 2-piece rotor assembly where specified, with the hats included and the parts assembled ready to install.
Do these reuse factory hats?
No. On listings sold as complete Paragon 2-piece rotor assemblies, the rotor hats are included. If your vehicle originally uses a factory 2-piece rotor, some other service-part listings may reuse the OE hats, but this product is sold as a complete assembly.
Do slotted rotors improve braking?
Slots primarily improve pad cleaning and help maintain consistent braking feel under heat. They do not create a dramatic change in stopping distance by themselves, but they can help the system stay more consistent during repeated hard stops.
When should rotor rings be replaced?
A practical wear indicator is slot depth. When the slots become shallow and much less visible, the rotor is typically nearing the end of its effective service life. Rotor thickness, heat checking, cracking, and brake vibration should also be inspected during service.
Brake Rotor Technology
Why high-carbon rotors matter
High-carbon cast iron offers better thermal stability than generic low-cost rotor materials. That helps the rotor maintain more consistent behavior as temperature rises, which is important on heavier vehicles and on cars driven aggressively.
Directional vane cooling
Directional internal vanes are designed to move air through the rotor more effectively, improving heat evacuation and helping the rotor recover more quickly between braking events.
Slotted rotor surface
Slots help keep the pad face clean by clearing away gases, dust, and debris. The result is more consistent pad contact and more repeatable braking feel, especially when the system is worked hard.
When to Replace Rotor Rings
Rotor rings should be replaced when the friction surface shows meaningful wear, heat fatigue, or thickness loss. One of the easiest visual indicators is the depth of the rotor slots. As the rotor wears, the slots become shallower. When they are much less visible, the rotor is generally nearing the end of its useful service life.
Other common signs include visible heat checking or cracking, brake pulsation, heavy scoring, and rotor thickness approaching the service limit.
Why Replace Rotor Rings Instead of the Whole Rotor?
This application uses a 2-piece design because separating the friction ring from the hat improves serviceability, heat management, and weight control. Compared with a heavy one-piece replacement, a quality 2-piece assembly can better suit performance-oriented vehicles where repeated heat cycles matter.
Common Mistakes When Replacing Rotors
- Not cleaning or inspecting the hat, hardware, and mounting faces
- Ignoring brake fluid condition during brake service
- Ordering the wrong configuration for the vehicle or hat type
Taking care of these details helps the new rotor deliver the braking feel, wear life, and consistency it was designed to provide.
