Overview

Brake Rotors

StopTech® offers a number of different brake rotors for a variety of applications. Whether it's for a daily driver, a work vehicle or a race car, all StopTech® rotors provide improved cooling, manufacturer equivalent or better specifications and a number of innovative design details that result in optimal stopping power.

Performance Brake Rotor Choices

A brake rotor’s primary function is to store and release thermal energy that is generated during the braking process. At first glance, two rotors from different manufacturers may appear to be identical, however, quality and performance cannot be determined by simply comparing the outside dimensions or aesthetics of the discs. Vane design, chemistry, metallurgy, casting methods and machining technique all contribute to the function of the disc once it is placed in service.

StopTech® has the engineering and R&D resources to test rotors on one of three Link brake dynamometers, on street and track vehicles, and in the laboratory. StopTech and Centric Premium brake rotors are designed, engineered, and built to offer significant braking advantages over OEM parts.

Innovation Through Superior Design

OE manufacturers recognize the need for corrosion protection, but also the need for immediate stopping performance. Many OE manufacturers have changed to brake rotors with partial coatings, especially on newer model vehicles. Dyno testing shows uncoated friction surfaces promote an immediate increase in stopping performance. GCX brake rotors, like many OE samples have overspray on the edges to ensure any unswept areas remain corrosion-free. Critical areas such as hub mounting surfaces are left uncoated, like OE.

  • Class leading application coverage for import and domestic passenger vehicles and light trucks
  • Superior protection from corrosion and rust even in the harshest of environments
  • Restores original factory appearance and performance
  • Engineered and manufactured for maximum durability and extended service life
  • Elemental Protection coating on rotor vanes prevents corrosion and promotes efficient rotor cooling

StopTech AeroRotors

StopTech AeroRotors

StopTech's patented AeroRotors® are 2-piece replacement rotors featuring a billet aluminum AeroHat® and AeroRotor® friction ring. These rotors feature a patented AeroVane® optimal cooling vane design to improve rotor airflow, cooling and heat capacity. This improved directional design minimizes turbulence and flows up to 61% more air than any rotor tested. Better airflow means better cooling and less fade.

The 2-piece design of the StopTech® AeroRotors® allows for independent expansion of the rotor and hat without coning. Additionally, AeroRotor® assemblies are up to 8 pounds lighter than stock rotors and are available either drilled or slotted. An optional anti-corrosion gold zinc coating benefits customers who live in cold climates, where snow and road salt are commonly encountered. Zinc coating also benefits customers who prefer no visible surface rust on the vanes and outer circumference of rotors. StopTech® AeroRotors® are 100% made in the USA, with both casting and machining taking place in California.

StopTech Sport Rotors

StopTech Sport Rotors

StopTech® Sport Rotors are direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer. Slotting and/or cross-drilling helps wipe away the debris that forms between the pad and the disc, adds more bite, and can help the rear brakes to match the aesthetics of a front big brake kit. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance.

Additionally, StopTech® Sport Rotors feature a durable black e-coating on the non-swept areas of the rotor to prevent corrosion. All StopTech® Sport Rotors are also available cryogenically treated to better align the molecular structure of the disc for enhanced durability and longer life. When so treated, they are known as StopTech Cryo® rotors.

GCX Elemental Protection Coated Rotors

GCX Elemental Protection Coated Rotors

GCX Coated Brake Rotors by StopTech with Elemental Protection™ feature a partial RS200 coating on the friction surface to ease bed-in and a full coating on the rotor vanes to prevent corrosion while promoting efficient rotor cooling. GCX rotors offer class-leading application coverage as well as superior protection from corrosion and rust. GCX rotors have been engineered to restore OE performance while offering maximum durability and extended service life. Like many StopTech rotors, GCX Coated Brake Rotors offer several key advantages over stock rotors.

Product Details

  • RS200 Coating - Partial friction surface coating results in 10% faster pad bed-in; eliminates corrosion rings on friction surface.
  • Double Disc Ground - Double disc grinding eliminates run out and allows more effective pad-rotor break in.
  • Machined Finishes - 100% fully machined finishes provide better rotor balance and a more finished look.
  • Symmetric Vanes - OE style vane designs provide proper heat transfer and thermal efficiency.

 

Centric Premium Rotors

Centric Premium Rotors

Centric® Premium Rotors are blank, 1-piece, direct replacement discs for your factory brake system. They feature Original Equipment specifications and production processes. Centric® rotors are manufactured to meet QS and ISO Quality System Standards. Like many StopTech rotors, Centric® Premium Rotors offer several key advantages over stock rotors.

Product Details

  • E-Coating - Electrocoating finish that provides long lasting corrosion protection.
  • Double Disc Ground - Double disc grinding eliminates run out and allows more effective pad-rotor break in.
  • Machined Finishes - 100% fully machined finishes provide better rotor balance and a more finished look.
  • Symmetric Vanes - Symmetric vane castings provide proper heat transfer and thermal efficiency.
  • Mill Balancing - Mill balanced to reduce feedback associated with rotor vibration.
