Paragon 2-piece Rotors (Rear Pair) for Tesla Model 3/Y Performance - oversize rotor
Upgrade your driving experience with the Performance OE Replacement Rotors for your Tesla Model 3/Y AWD Performance. These larger 370/380x23mm rotors not only enhance your vehicle's performance but also offer improved braking power and control. Push yourself to the limit and conquer any road with confidence!
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. The floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads. 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. Weighing less than most O.E. rotors while maintaining proper thermal capacity, our 2-piece rotors improves overall handling by saving unsprung mass.
Aluminum hats are CNC machined from lightweight 6061-T6 aerospace grade aluminum for high strength and durability under extreme track conditions, then black hard coat/hard anodized to increase resistance to wear and corrosion. Mil-spec Type III anodized hats will not discolor under extreme heat, and are harder and more wear/scratch resistant. Unnecessary materials are taken out from the aluminum hats for maximum weight savings while maintaining proper structural integrity. *Black hard coat and hard coat anodized hats are the same in terms of performance and durability.
Direct bolt-on without any modifications and designed to work flawlessly with OEM ABS and brake system while maintaining factory brake bias. Compatible with OEM brake pads or aftermarket pads with the same pad depth (D)
Directional ventilation vanes for optimal cooling performance, runs up to 30% cooler than O.E. rotors and increase cooling efficiency by up to 30%. Great upgrade from stock pillar vane rotors
Increases rear rotor diameter by 35-45mm / 1.38-1.77"
Further increases brake torque over O.E. sized 2-piece rotors due to improved leverage
Increased thermal capacity to absorb and dissipate the heat generated more efficiently

Front rotor for my volvo v60 polestarl
Needed a front brake job on my 2015 Polestar. The only place that could sell me the rotor was my local Volvo dealer, for a total of 2200can$ all tx included. Bought Paragon rotor from Alcon Brake for 1500can$ all included. No braokage fee. The quality is superb and the customer service is quick and friendly.
Merci AK!

Great brake rotors for Porsche Cayman GT4
The Alcon rotors are serviceable, hats are of excellent quality and are at a good price. I recommend them! I have 4 track days on them and they look fine. Sebring International Raceway isn't easy on brakes either.

Frequently asked questions on Alcon Brakes
Why buy from Alconkits.com?
Can I buy Alcon Brakes and parts somewhere else?
Yes, some general automotive retailers and online marketplaces may list Alcon brake kits or individual components. However, Alcon brake systems are engineered, vehicle-specific systems, not commodity parts.
When purchased from Alconkits.com, you are buying directly from a specialist Alcon distributor with deep application knowledge, fitment validation experience, and long-term service support. This ensures you receive the correct configuration, pad compound guidance, wheel-clearance assistance, and ongoing support throughout the life of the brakes.
Why should I buy this kit from Alconkits.com instead of a retailer like eBay or Amazon, or marketplace?
Alconkits.com specializes exclusively in Alcon brake systems. We are not a general parts reseller.
When you buy from Alconkits.com, you get:
Application-specific guidance for heavy trucks like the Ram TRX
Fitment advice on your brakes to ensure they clear your wheels with guaranteed compatibility with your vehicle.
Wheel-fitment and clearance validation support
Pad compound recommendations based on real-world use (street, off-road, towing, track)
Access to replacement pads, rotors, seals, and service parts long after purchase
Lifetime technical support from Alcon brake specialists
Most marketplaces can sell a box. We support the entire brake system lifecycle for as long as you own it.
What makes Alcon big brake kits different from other aftermarket brake options?
Alcon brake kits are engineered systems, not assembled collections of parts.
Each kit is designed with:
Vehicle-specific caliper piston sizing
High-mass rotors for thermal capacity on heavy vehicles
Motorsport-grade materials and manufacturing processes
Compatibility with factory ABS, traction control, and master cylinder
This results in more consistent pedal feel, better heat management, and superior durability compared to budget or generic big brake kits.
Are Alcon brake parts “one-size-fits-all”?
No. Alcon brake kits are application-specific.
Vehicle weight, intended use, rotor size, caliper configuration, and pad compound all matter—especially on high-performance cars and trucks. Selecting the wrong configuration or pad compound can reduce braking performance, increase noise, or accelerate wear.
This is why buying from the specialist distributor, Alconkits.com, matters.
What type of driver is Tesla Model 3/Y AWD Performance - Larger Rotor Performance 2 Piece Rotors - (Rear) 370/380x23mm for?
Manufactured by Paragon Performance, we recommend this as being suitable for the following driving styles:
Street
Sporting
Street/Track
Armored/OffRoad
Track/Race
After purchase support questions.
What happens if I need pads, rotors, or service parts in the future?
This is THE question to ask. Alcon brake systems are fully serviceable.
When you purchase from Alconkits.com, you have long-term access to:
Replacement brake pads
Replacement rotors
Seal kits and service components
Technical guidance for maintenance and service intervals
This is a major advantage over marketplace sellers who may not support the product after the sale. We know what fits, we stock it, and we don't sell you parts you don't need.
Why does this Alcon brake kit cost more than stock brakes or some aftermarket options?
Alcon brake kits are built to deliver higher performance, durability, and consistency than OEM or budget aftermarket brakes.
The cost reflects:
Larger, higher-mass rotors for heat control
Precision-machined multi-piston calipers
Motorsport-grade materials and testing
Long-term serviceability and support
