MR2Heaven Ultimate Wilwood FRONT BIG Brake Kit - 1991-1998 MR2

What our kits will do for you

Some important questions people often have

• Stops on a dime? - Absolutely. With BP10 or BP20 pads, this brake system will handle whatever you throw at it, performing consistently lap after lap on the race track. These components are built to last for the lifetime of your MR2
• Affordable - If you're looking for a budget-friendly option without all the extras like 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.
• Confidence Inspiring? - Absolutely. These components are designed for durability, originally meant to stop heavier vehicles weighing 3560-3700+ lbs. They manage temperatures effectively, ensuring all components last longer and can handle heat lap after lap without issues. Consistent temperatures mean a stable brake pedal feel, boosting confidence during braking. 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 calipers have been a favorite among MR2 track enthusiasts for nearly 20 years.
• Will my MR2 look great? - Absolutely! Rotors are large and you'll look even cooler with bright red calipers and dual rear calipers paired with our exotic J-hook 2-piece rotors, featuring optional bright gold top hats. Our BBKs has won numerous first-place awards for many owners.
• What is maintenance like? - Maintenance is minimal. The pads and rotors are designed to last for years. It is recommended to flush your brake fluid every 2-3 years, similar to the maintenance schedule for any other car. This helps ensure optimal performance and longevity of your brake system.
• Will i have to change master cylinders? How is brake bias and pedal feel? What if i buy only the front kit? - No need to change the master cylinder if it's functioning properly. The brake bias with both front and rear kits is well-balanced, similar to OEM, and even better optimized. The pedal feel is solid, with an impressive and consistent bite from the BBK. 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.
• 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.

• Large Diameter - Everyone wants larger brakes for good reason; they're essential for achieving excellent braking performance and reducing overall brake temperatures. Our BBK meets this need with impressive 12.72" (323mm) rotors for both the front and back. Not only do they perform well, but they also look fantastic, filling up most 17" wheel gaps nicely.
• Lightweight -  With advancements in technology, big brakes don't have to be heavy. Our flagship 2-piece rotors, featuring an aluminum center and iron disk, combined with Wilwood Forged Superlite Calipers, offer a total weight savings of 22 lbs compared to the factory brakes they replace. Specifically, Wilwood FSL calipers provide a 14 lbs savings, while each rotor saves 2 lbs.
  
• Track Ready Rotors -  All our rotors are designed and proven for track use. The combination of Supra/RX8 323mm rotors with Wilwood FSL calipers has been a reliable solution for the much lighter MR2 for nearly 20 years. This FSL/Rotor combo is robust and dependable, handling any challenge without issues.
• Beefy Rotor Ring Thicknesses & Rotor Cooling - Our flagship 2-piece rotors are engineered for maximum durability and cooling efficiency, featuring 65 curved directional vanes—more than most, like the 54 found in StopTech rotors. This design ensures temperature stability and cooling, akin to endurance race rotors. Our lightweight rotors match the thickness and cooling surface area of the larger rotors they replace, offering heavy-duty performance, longer lifespan, reduced thermal shock, and lower overall operating temperatures.
• Superior Heat Capacity & Management/Lower Temperature Benefits
  • Consistent & Confidence Inspiring Brake Pedal Feel - Essential for racing, our large-diameter rotors with beefy rotor rings minimize temperature fluctuations, maintaining stable brake pad friction and bite. This consistency in brake pedal feel enhances driver confidence, ensuring reliable performance lap after lap.
  • Reduced Rotor Cracking - In 16 years of experience with this BBK combo in the forums and community, I haven't seen a single case of rotor cracking. This issue often occurs due to large temperature spikes in small, lightweight, or thin rotors—common in inadequately sized systems. Our rotors are designed to be thick, robust, and sturdy, preventing such problems and ensuring durability.
  • Longevity & Low Operating Costs - Our big brake kits run at lower average temperatures, allowing them to last 7-11+ intense track days or many years before needing pad and rotor replacements. This durability contrasts with some competitors, who may require rotor changes every 1-2 years with regular street use.
  • Headache free - Our brake kits are designed for reliability and longevity. When components aren't pushed to their limits, they tend to last longer and operate without issues, providing a hassle-free experience.
  • More Pad Choices - Thanks to lower operating temperatures, you can opt for street pads instead of noisier track pads, giving you more flexibility in choosing the best pads for your driving style and needs.
• Modular, Interchangeable, Affordable & Wide Range of Solutions - Our brake kits offer modular and interchangeable parts, allowing you to choose from various styles, patterns, and performance levels at different price points. With ample aftermarket support, you won't be reliant on a single brand, ensuring the longevity and versatility of your brake kit for years to come.
• 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.

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. 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. They also eliminate unused rotor space found in one-piece rotor rings. 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.
