  • We ship worldwide

The Best & Most Popular Big Brake Kit (BBK) for MR2s. Enjoy numerous exclusive benefits with our kit. Most of us know MR2 factory brakes fall short and can become very dangerous & unpredictable with as little as 2-3 hard stops. With a quick glance at the absurdly small size of a rotor, its no surprise

What our kits will do for you

Some important questions people often have

  • Stops on a dime? - Absolutely. Our BBKs will handle whatever you throw at it, performing consistently lap after lap on the race track
  • Budget Friendly - If you don't need optional powder coated red calipers and lightweight two-piece rotors, you can get a fully track-ready front big brake kit (BBK) for as little as $770-$850.
  • Track Ready Rotors & Pads -  All our rotors are designed and proven for track & can even handle endurance 24+ hour racing. The combination of Supra/RX8 323mm rotors with Wilwood FSL calipers/BP pads has been a reliable solution for the much lighter MR2 for nearly 20 years. 
  • Confidence Inspiring? - Absolutely. Originally engineered to stop heavier vehicles weighing 3,560-3,700+ lbs. When used on an MR2, they effectively manage brake temperatures, ensuring extended component lifespan and consistent performance lap after lap. Stable temperatures leads to reliable brake pedal feel & performance, instilling confidence and critical for racing. The kit, including calipers, DOT-approved stainless steel brake lines, brake pads, and Grade 12.9 hardware, is Made in the USA. The Supra/RX8 rotors with Wilwood FSL caliper combo have been the go to favorite among MR2 track enthusiasts for nearly 20 years.
  • Will my MR2 look great? - Absolutely! Rotors are large and fills in wheel gaps nicely. Bright red with optional dual rear calipers (usually only found on supercars) paired with our exotic J-hook 2-piece rotors and brightly anodized gold top hats will turn heads wherever you go. Our BBKs has helped win numerous first-place awards for many owners.
  • Lightweight - Will i save weight? - Yes, thanks to advancements in technology, big brakes no longer need to be heavy. Our BBK with flagship 2-piece rotors—crafted with an aluminum center and iron disc—paired with Wilwood Forged Superlite Calipers, deliver a total weight reduction of 22 lbs compared to the factory brakes they replace. However, lighter isn’t always better. While we could have made our 2-piece rotors even lighter, this would compromise the thickness of the faces and reduce the number of cooling vanes, leading to reduced durability, rigidity, shorter lifespan, lower capacity, increased thermal shock/stress, and diminished performance, ultimately requiring much more frequent replacements as we have seen other kits suffer from.
  • Large Diameter & Thicknesses?- Absolutely. Everyone wants large brakes for good reason; aside from appearance aspect, they're essential for achieving excellent braking performance and reducing overall brake temperatures via higher cooling capacity. Our BBK meets this need with impressive 12.72" (323mm) diameter for both the front and back & 30-31.75mm thickness overall for front rotors, taking full advantage of space and maxing out the capacity of the front calipers.
  • Rotor cooling & why is it important? - Larger rotors with a high vane count is desired because their increased surface area enhances heat dissipation, allowing them to conduct cooling more effectively and quicker from the air. 
      • Prevents Brake Fade - When rotors overheat, braking effectiveness diminishes—a phenomenon known as brake fade.
      • Extends Component Lifespan - Excessive heat causes premature wear and potential warping of rotors, pads. 
      • Ensures Consistent Pedal Feel - Heat buildup can impact the brake pedal feel, making it softer or less responsive. Adequate cooling helps maintain a stable pedal feel, so drivers can anticipate braking performance with confidence.
      • Minimizes thermal shock - Rapid changes in temperature can cause thermal shock, which leads to cracking or uneven rotor wear. Cooling prevents extreme temperature spikes, reducing the risk of damage and ensuring rotors remain durable under intense use
      • Improved Heat Distribution - Larger, high-vane rotors distribute heat more evenly across the rotor surface. This uniform heat distribution minimizes the likelihood of hot spots, which can lead to uneven wear, rotor warping, or even cracking over time.
      • Reduces Risk of Brake Fluid Boiling: When rotors get extremely hot, the heat can transfer through the calipers to the brake fluid. If brake fluid boils, it produces air bubbles, leading to a soft or “spongy” brake pedal and a loss of braking power.
      • Enhances High-Speed Braking Performance: During high-speed braking, rotors face greater demands and generate significantly more heat. Larger, well-cooled rotors can dissipate this heat quickly, ensuring that braking performance remains consistent even at higher speeds or during repeated heavy braking.
      • Supports Lower-Grade Pads: Effective rotor cooling allows the use of lower-grade brake pads, as the rotors handle much of the heat management. This can be more cost-effective, as high-grade pads tend to wear more quickly and are often more expensive. With better cooling, lower-grade pads can perform reliably without compromising performance.
      • Enhances Safety in Emergency Braking: In emergency braking situations, having cool, well-functioning rotors ensures the brakes respond immediately and effectively. Overheated rotors could lead to delayed braking response or decreased stopping power, which can be dangerous.
  • Rotor cracking - No, our rotors are unlikely to experience high thermal shocks, operating at very high temperatures or close to its limits. In 16 years of experience with this BBK combo in the forums and community, we haven't seen a single case of rotor cracking. This issue often occurs in inadequately sized systems or on lightweight thin rotors. Our rotors are designed to be thick, robust, and sturdy, preventing such problems and ensuring durability.
  • Headache Free? - Yes, Our brake kits are engineered for heavy-duty performance, prioritizing consistency, reliability and longevity. By avoiding extreme stress on components, they last longer and operate smoothly, offering a hassle-free experience.
  • What are operating costs & maintenance like? - Operating costs & maintenance is minimal thanks to running properly sized large thick heavy duty rotors as compared to other kits (thin lightweight 12.19") or OEM that require replacement every track day or 1-3 years. Our pads and rotors are designed to last for 5-10+ years, and good for at least 7-11+ extreme track days. Some owners even reported 50 hours of continuous 24 hour endurance racing before changing pads. As with all cars, it's recommended to flush your brake fluid every 2-3 years. This helps ensure optimal performance and longevity of your brake system. 
  • Will i have to change master cylinders? - No need to change the master cylinder if working properly
  • How is brake bias and pedal feel? What if i buy only the front kit? - Bias with both front and rear kits is well-balanced, similar to OEM, and even better optimized. If you choose only the front kit, there are no issues, as the piston sizes and ratios between the front and rear are not overly aggressive or significantly different from stock.
  • Easy and Quick Pad Changes on Wilwood Caliper - Changing pads on Wilwood calipers is straightforward. Just remove the wheel, loosen a nut, and slide the pads in and out one at a time.
  • Is this everything i will need? - Yes, this is a complete kit that includes everything necessary to replace your original working brakes, except for the brake fluid. You'll need to purchase DOT 3-5 brake fluid separately.
  • What are some other advantages & exclusive benefits with this kit? - This kit is highly interchangeable, modular, not dependent on any single brand (more interchangeable caliper choices in the upcoming future), offers high braking performance regardless of your budget. Our 2-piece rotors are custom-designed and specifically optimized for MR2s, manufactured exclusively for us, and free from the limitations of off-the-shelf parts, which often present drawbacks when adapted for MR2s. With that being said, our design features class-leading 65 curved vanes for exceptional cooling and durability, along with optimized diameters, mass, and thicker faces that withstand intense use, reduce high-temperature shocks, and resist quick wear. In contrast, smaller, thinner rotors like the 12.19” often need replacement every 1-3 years with regular street use and typically require higher-grade brake pads. Another added exclusive bonus is free temperature indication changing paint applied on our 2-piece rotors.

Notes

Brake Bias - Our front and rear kit, when combined, delivers brake bias dynamics that meet or surpass OE standards:

  • With an OEM Non-Turbo Brake proportioning valve, our F&R kit performs exceptionally well with BP10 & BP20 pads, significantly improving OEM 1993+ Turbo Brake Bias curves. It achieves 60-63% front bias from 0.5 to 0.7G and maintains an ideal 63%-68% front bias from 0.7 up to 1.4G. This helps prevent rear wheel lock-ups as weight shifts to the car's front during hard braking.
  • With an OEM Turbo Brake proportioning valve, our F&R kit performs decently with BP10 & BP20 pads. It maintains a stable 62-64% front bias and around 36% rear bias from 0.5 to 1.4G of deceleration, similar to the OEM 93T brake bias.

Disclaimer - These brake components are designed for off-road use only and should not be used on streets or highways. By ordering from us or using our supplied brake parts, you agree that we are not responsible for any damages, injuries, accidents, or deaths. All responsibility lies with you.

Technical Supplemental Information

Brake Rotors

We carry a variety of rotors in-house, but if international shipping costs are a concern, you can order your own rotors to save on shipping. Check out our full rotor part number table for more options. Link to Full Rotor Part # Table

Our Flagship 2-Piece Rotor Solution - Exclusively designed for our big brake kits and not compatible with Supra or RX-8 vehicles, this rotor solution results from extensive research and refinement. With over 83 rotor designs analyzed, we've achieved a perfect blend of balance, heavy-duty usage, weight savings, and maximum performance for the MR2. They also eliminate unused rotor space found in one-piece rotor rings. Featuring race-grade 65 curved internal cooling vanes, these rotors provide nearly the same cooling surface area as full-sized rotors while being significantly lighter. Front rotors weigh approximately 14-14.5 lbs, and rear rotors 10.5 lbs, offering superior cooling and performance. They meet G3500 grade iron standards and feature black E-coating for added corrosion resistance.



Free temperature-changing paint indicators - Factory-applied heat indication paint markers, valued at $150, are included at no extra cost on our 2-piece rotor offerings. The green paint transforms to white when rotor temperatures exceed 840°F, while the orange paint shifts to white at 1020°F. When rotor temperatures reach 1200°F, the red paint changes color.

Brake Pads

We recommend BP10 and BP20 pads for optimal performance.

BP10 pads are ideal for street and moderate track use, offering a high temperature range (up to 950-1050°F) and minimal to no noise.

BP20 pads are suited for more frequent track use, handling up to 1200-1250°F but may squeal loudly when cold.

Higher temperature pads like BP-30 and BP-40 are designed for race use only and are not recommended for street use due to poor cold performance and noise.

We also carry HAWK, and EBC pads, all of which are rigorously tested and proven. Other brand pads such as Carbotech, PAGID, StopTech, Project Mu also works, but to simplify logistics, we only carry HAWK, Wilwood and EBC. 

Calipers & Hardware

Wilwood Forged Superlite Calipers feature a lightweight, 4-piston design that is both budget-friendly and track-proven. Manufactured in the USA, these calipers can be powder-coated in Black or Red, or even custom colors for an additional $1400. Alternatively, you can order Gray and customize the color yourself. Replacing your stock calipers with these Wilwood calipers saves approximately 14 lbs in weight. Selected to maintain brake bias on both Turbo and NA MR2 models, these calipers are a high-quality and stylish upgrade. We stock gray, red, and black calipers in-house, so no 3-4 week wait time is necessary.

Premium Brake Caliper Mounting Brackets are crafted from a single piece of CNC-machined 6061-T6 aerospace-grade aluminum, providing strength and durability while being one-third the weight of most mild steel alternatives. These brackets are hard-anodized for exceptional protection against extreme environments.

High-quality, US-made D.O.T. approved one-piece brake lines are crafted from premium PTFE cores, zinc-plated steel fittings, and stainless wire braided covers, all encased in a clear PVC outer layer for protection against chemicals, elements, and debris. These lines prevent swelling, expansion, and rubber deterioration commonly seen in stock OE lines. In contrast, some MR2 sellers use cheap, unbranded lines with multi-piece fittings, which are prone to leaks and deformation due to cost-cutting measures. Be aware of the potential risks associated with inferior products.

High-Quality Hardware Kit features heavy-duty Grade 12.9 black oxide bolts/screws, stainless steel and zinc-coated washers, and lock washers, all sourced from the reputable McMaster Carr. These components are designed to withstand harsh environments.

For Two-Piece Rotor Assembly, we use 18-8 stainless steel socket head cap screws and U.S. Military Standard 21042-5 self-locking "jet nuts" to secure the top hat to the rotors, eliminating the need for safety wire.
