PATENTED COOLING TECHNOLOGY
StopTech Brakes: Engineered Cooling That Changes Everything
StopTech Brakes don’t just stop; they manage heat with precision. Our AeroRotor Two-Piece Brake Rotors feature a patented aerodynamic cooling vane pattern that channels air through the rotor assembly. This design actively pulls heat away from the friction surface, promoting even cooling and drastically reducing the risk of thermal distortion and fade during repeated hard stops.

More effective heat dissipation
A Legacy Built on Track Days
For over two decades, StopTech has been the go-to name for performance enthusiasts who demand more from their brakes than daily driving ever asks. This isn’t a story of overnight success—it’s 23 years of continuous refinement, starting where braking matters most: the race track.
Born from Motorsport, Not Marketing
StopTech’s first products were designed for, and tested in, actual racing conditions. This origin means every component is over-engineered for the punishment a spirited canyon run or track weekend dishes out—a level of durability that standard commuter-brake parts simply aren’t built to provide.
Data-Driven Engineering Evolution
Each new product generation isn’t just an aesthetic refresh. StopTech engineers analyze failure data and thermal performance from the previous version, then refine the design. A 23-year feedback loop from performance enthusiasts means today’s kits solve problems that were identified on track 15 years ago.
Balanced Stopping as a Core Principle
Where many aftermarket brands focus solely on raw clamping force, StopTech designs for balance—ensuring front-to-rear brake bias remains optimal. This prevents the dangerous scenario where one axle locks up while the other underperforms, a critical safety consideration for high-speed driving.
The Two-Piece Rotor Advantage
StopTech championed the use of two-piece, floating rotor assemblies in the enthusiast market. This design allows the aluminum hat and iron rotor ring to expand at different rates under heat, dramatically reducing the risk of rotor warping and the steering wheel shake it causes.
Application-Specific, Not Universal
A StopTech big brake kit for a 2015 Ford Mustang GT is engineered specifically for that chassis’s knuckle geometry, wheel clearance, and weight distribution. There’s no generic “one bracket fits many” approach here, which ensures proper pedal feel and ABS compatibility out of the box.
A Complete System Philosophy
StopTech recognizes that rotors, pads, and lines are interdependent. Offering all three categories allows them to engineer components that work in concert—like matching pad friction levels to rotor metallurgy for predictable bite and release, something impossible when mixing random brands.
TRACK-DAY STORY
STR Race Big Brake Kit
★ 4.9 · 87 reviews
Marcus runs a 2019 Civic Type R at Laguna Seca. Last October, he swapped the stock setup for the STR Race Big Brake Kit. His lap times dropped by 2.1 seconds on the first full session. The quick-release caliper pins let him swap pads between runs in under four minutes—no jack required. He called it ‘the single biggest lap-time gain per dollar I’ve ever found.’ The kit’s weight savings over the ST Sport version mattered less on the street, but every ounce counts when you’re chasing tenths on the Corkscrew.
- Forged, unpainted calipers cut unsprung weight for sharper turn-in
- Two-piece AeroRotors with directional vanes resist fade through 20-minute sessions
- Quick-release pin system enables sub-4-minute pad swaps without removing the caliper
- Stainless-steel braided lines included—no separate line kit needed
- Application-specific brackets for direct bolt-on fitment on 35+ platforms
Rotors, Pads, and Kits Explained
StopTech engineers each component type for a distinct purpose. Your upgrade path depends on whether you need bite, heat management, or a complete system overhaul.
Brake Rotors
Replace your stock discs with engineered alternatives. Two-piece AeroRotors reduce unsprung weight and manage heat with aerodynamic vanes, while Sport slotted or drilled versions offer improved bite and gas venting for direct bolt-on upgrades.
Brake Pads
Match your friction material to your driving. The 309 Series handles aggressive track abuse, the 308 Series balances street and spirited use with less dust, and the 105 Series ceramic offers quiet, clean OE replacement.
Big Brake Kits
These complete systems pair forged calipers, larger-diameter two-piece rotors, braided lines, and mounting hardware into a single engineered package. The ST Sport kit delivers dramatic street/track gains, while the STR Race kit is tuned for competition.
Find the Right Pad for Your Commute
Daily driving demands predictable, low-drama braking. Compare the Street Performance 308 Series for sharper bite and less dust, or the Street Select 305 Series for a quiet, OE-plus upgrade that still improves feel.
Sport Brake Pads (309 Series)
High-friction compound for spirited weekend drives.
Street Performance Brake Pads (308 Series)
Confident daily stops with improved bite and less brake dust on wheels.
Street Select Brake Pads (305 Series)
A noticeable upgrade over stock pads for everyday driving comfort and control.
Choosing Your Friction: Ceramic to Race
Not all stopping friction is equal. Selecting the right brake pad compound means matching heat tolerance, bite, and noise to your specific driving demands.
Operating Temperature Range
The range of heat (measured in Fahrenheit) where the pad compound is most effective. Street pads work cold; race pads need heat to perform.
Friction Coefficient (Mu)
The measure of how ‘grabby’ the pad is. Higher mu means stronger bite but can require more pedal modulation skill.
Noise, Vibration, Harshness (NVH)
How much squeal, pedal feel feedback, or harshness the compound produces. Ceramic compounds typically score best here.
Dust Output
The amount of particulate matter the pads shed, which coats your wheels. Low-dust ceramics are popular for this reason.

Your Top Stopping Questions, Answered
Clear, direct answers to the most common questions about upgrading your vehicle’s braking system with StopTech components.
The ST Sport Big Brake Kit is engineered for specific vehicle applications, and fitment is not universal. Clearance depends on your wheel’s inner barrel diameter and spoke design. Always use the application-specific fitment guide on our retailer’s site and verify clearance with the supplied template before purchase. You may need to run a wheel spacer with some OEM wheel designs.
Lifespan varies significantly with driving style and conditions. A two-piece AeroRotor used primarily on the street might last 40,000 to 70,000 miles, while frequent track use could shorten that to several high-performance events. Monitor the rotor’s minimum thickness spec, stamped on the hat, and replace them when you reach that measurement—typically around 1.25mm above the minimum.
It’s not mandatory for a simple rotor swap, but it’s a smart, low-cost upgrade. Stock rubber lines can expand under hard pressure, causing a spongy pedal feel. Upgrading to stainless steel braided lines—like those included in the ST Sport Big Brake Kit—provides a firmer, more consistent pedal response by minimizing this flex.
You should perform a proper bed-in procedure every time you install new pads or rotors, and after any event that has glazed the pads (like a track day followed by a cooldown without proper cycling). A proper bed-in transfers an even layer of pad material onto the rotor surface, which is critical for optimal bite and even wear.
Yes, and this is a very common and effective configuration. The front brakes handle 60-80% of the stopping force, so upgrading to a kit like the ST Sport on the front axle yields a dramatic improvement in stopping power and modulation. The stock rear brakes will function perfectly fine with the enhanced front system.
Slotted rotors don’t require special maintenance, but they do have a predictable wear characteristic. The slots will gradually disappear as the rotor wears down. This is normal and indicates the rotor is nearing the end of its service life. Replace the rotors when the slots are no longer clearly visible or you reach the minimum thickness spec.
