Find the perfect gear for your brakes

Unleash your vehicle’s true braking potential with StopTech’s legendary performance lineup. From daily drivers to dedicated track machines, StopTech engineers every component to deliver race-derived technology, unmatched durability, and confidence-inspiring stopping power for enthusiasts who demand the very best from every pedal press.

Complete StopTech Brake Kits

Upgrade everything in one go with a StopTech brake kit, featuring calipers, rotors, pads, and stainless steel lines. Perfect for street, canyon, and track use, these matched systems deliver balanced performance and effortless installation, ensuring every component works harmoniously for maximum stopping confidence on any road.

High-Performance Rotors & Hardware

Choose StopTech brake rotors, slotted rotors, or the rotor hardware kit for noticeable gains in heat management and pad bite. Precision-machined surfaces and premium metallurgy reduce fade during aggressive driving, while the hardware kit ensures secure, rattle-free mounting with corrosion-resistant fasteners built for long-term reliability.

Calipers Built for Power

StopTech calipers, including the ST-40, ST-41, ST-60, and forged brake calipers, deliver stiffness and clamping force that unlock serious performance. Paired with the ST-60 hardware kit for easy rebuilds, these forged multi-piston units bring race-proven engineering and striking looks to nearly any performance vehicle on the market.

Performance Pads & Sport Upgrades

Match your rotors with StopTech brake pads or StopTech Sport Pads for serious bite and controlled modulation. Formulated for street-friendly manners with track-ready confidence, these pads minimize noise, dust, and fade while extending rotor life — perfect for spirited drivers who want refinement without giving up aggressive stopping power.

Stainless Steel Brake Lines

Swap tired rubber hoses for StopTech brake lines or StopTech steel brake lines and feel the difference instantly. Braided stainless construction resists expansion under high pressure, giving you firmer pedal feel, faster response, and better modulation whether you’re carving backroads or lining up for the next hot lap.

Signature Big Brake Kits

The StopTech Big Brake Kit — including popular setups like the 950.61001 and 309 series — combines ST calipers, two-piece rotors, and performance pads into one race-engineered package. Ideal for enthusiasts who want serious stopping distance reductions, improved fade resistance, and an aggressive visual upgrade behind their wheels.

From 1999 to Today: A Legacy of Control

Before ‘big brake kits’ became a searchable term, StopTech was engineering them. The company launched in 1999 with a singular focus: building high-performance brake systems that gave drivers measurable control over their vehicles. That first year, a set of its forged calipers and 2-piece rotors went from a Huntington Beach garage to a track-day staple.

1999

StopTech founded with a mission to bring balanced brake upgrades to the performance aftermarket.

2005

Secured a patent for the AeroRotor design, establishing a new standard for rotor cooling efficiency.

2012

Brake systems endure the punishing conditions of desert racing, proving durability beyond street applications.

2019

Celebrated 20 years with over 100,000 brake kits installed across North American vehicles.

Why Balanced Upgrades Mean Better Control

StopTech’s Balanced Brake Upgrade philosophy ensures every component works in concert, delivering predictable, linear performance from daily driving to the edge of adhesion.

Front-to-Rear Proportioning

Calipers, rotors, and pads are selected as a matched system for your specific vehicle’s weight distribution. This prevents the common upgrade mistake of over-powering the front brakes, which can destabilize the chassis during hard stops and lead to premature rear lockup.

Thermal Stability Under Load

Patented 2-piece AeroRotors feature a 6061-T6 aluminum hat that manages heat transfer, resisting fade during repeated high-energy stops like those encountered on a canyon road or entering Turn 1 at Laguna Seca.

Pedal Feel Consistency

Stainless steel braided lines reduce volumetric expansion by over 30% compared to OE rubber hoses. This translates a consistent 40-pound pedal force into precise caliper piston actuation, lap after lap.

Unsprung Weight Management

A forged aluminum 4-piston caliper and a 2-piece rotor assembly can save up to 8 pounds per corner versus a heavy cast-iron upgrade. This reduction improves suspension response and steering precision, especially in mid-corner corrections.

Six Cooling-Rotor Patents, Six Ways to Stop Better

Each StopTech series pairs our patented 2-piece AeroRotors with a distinct engineering priority—from daily-driver quiet to track-day endurance—so you can match the brake system to exactly how and where you drive.

01. AeroRotor Track Systems
Drivers who regularly see track sessions or aggressive mountain runs
Largest rotor diameters and maximum vane count translate heat into airflow, pulling air through curved vanes at speeds that drop rotor temps by up to 180°F between hard stops.
02. Cryo-Street Rotors
High-mileage commuters who want minimal maintenance
Cryogenic treatment at -300°F restructures the iron grain, giving these slotted rotors 2–3× longer service life while the e-coated hat fights corrosion through Midwest winters.
03. Sport Slotted Series
Spirited street driving and occasional autocross
Directional slots wipe the pad surface clean each revolution, maintaining a consistent friction edge without the cracking risk of cross-drilled holes.
04. Select Sport Drilled & Slotted
Show-car aesthetics with genuine performance gains
Combining drilled holes for rapid gas venting with curved slots for pad cleaning, these rotors shed heat 12% faster than plain-face alternatives on repeat highway-to-off-ramp stops.
05. Street Performance Pad Line
Daily drivers who notice brake dust on alloy wheels
Low-dust ceramic-compound formulations keep wheels cleaner through 8,000+ city miles while retaining a friction coefficient above 0.42 μ once warmed to operating temp.

Slotted or Drilled? Your Rotor Questions Answered

Choosing between slotted and drilled brake rotors depends on your driving habits. This section clarifies the differences to help you pick the right StopTech rotor for your needs.

Quick Help

Can’t find what you’re looking for? Reach out and we’ll get you sorted.

StopTech Sport Slotted Brake Rotors have channels cut into the surface to wipe away gas and debris, while the Select Sport Drilled and Slotted Brake Rotor adds holes for additional heat venting. Slotted rotors generally resist cracking better under hard use.

Yes, the drilled holes in rotors like the Select Sport Drilled and Slotted model can create stress points that may develop cracks with repeated heavy braking or track use. Purely slotted designs, such as the Sport Slotted rotors, are engineered for greater resistance to this type of failure.

For a mix of spirited street driving and occasional track use, StopTech Sport Slotted Brake Rotors are a strong choice. They manage heat well and are less susceptible to the cracking that can affect drilled patterns under sustained high temperatures.

The drilled and slotted pattern can sometimes produce a slightly more audible ‘swooshing’ sound compared to plain or slotted rotors as the holes and slots pass the pad. This noise is typically minimal and not a concern for most drivers.

Choose Sport Slotted rotors for maximum durability and a focus on consistent bite, especially if you drive aggressively. The Select Sport Drilled and Slotted model is a solid option for enhanced initial bite and heat evacuation in less demanding, primarily street-performance applications.

It depends on the specific pad. Their Street Performance pads are optimized for low dust and noise on the street and may fade under aggressive track use. For serious track duty, their Sport or dedicated track pads are recommended.
