The Most Proven & Popular BBK for the SW20 (1990–1998 MR2s) — For Good Reason

The factory MR2 Turbo brakes are dangerously undersized. With just 1–3 hard high-speed stops, the OEM brakes will overheat, fade, or warp— putting your car at serious risk. At a glance, it’s obvious: the rotors are very tiny, thin, and not built for modern power levels, speeds, or repeated heavy use. 

What our kits will do for you

Exclusive MR2Heaven Big Brake Kit Advantages

  • Numerous rotor/Pad choices - Not limited by one brand and their price hikes & parts availability - Freedom, affordability and longevity in mind. 
  • Perfectly Sized System - Built on heavy-duty 12.72" rotors front and rear, all of our rotor and pad options (rated above 950°F) are true track-ready setups — lightweight, durable, and engineered to take lap after lap of punishment without issues. In real world testing, paired with only BP10 pads (~1050°F), our 12.72" rotors easily support aerodynamic mods (large front splitter/rear wing), 400whp/395tq, and 275-wide square racing slick tires with over 10,000–12,000+ track miles over 5 years, piloted by countless professional & notable racing drivers — completely headache-free with room to grow (w/ BP20 pads).
    • While others run undersized 12.19" rotors, our 12.72" 1 and 2-piece rotors belongs in a class of its own, combining larger diameter with 60–65 curved vanes (vs. 48) for unmatched cooling rates. The result? 100–200°F+ cooler rotor temps against 12.19" competitor just with 1x 140-0mph stop (and about 700°F lower temps over stock 91T rotor), no fade, and zero need for $1,100+ annual rotor and pad replacements like our competitors running undersized 12.19" rotors with band-aid upsized pad compounds. 
    • Physically speaking, our competitors undersized 12.19" rotor ring (12.7 lbs) heats up quite more than the OEM 93T rotor ring (14.0 lbs) per braking event due to having less mass, even though the full 93T rotor weighs ~17.5 lbs. However, the 12.19" rotor ring compensates with slightly better cooling rate and is still considered a slight performance upgrade over the 93T brakes due to relying on running high temperature race pads (BP20s). That said, both our 1-piece and 2-piece rotors easily surpass the 12.19" in total cooling vane surface area—just as they do compared to the 93T. In simple terms: more mass & higher cooling rate = significantly lower running temperatures. 
    • The end result? Our class-leading, endurance-race-level 65-vane lightweight 2-piece rotors weigh 1.5–3.5 lbs more each — but that slight increase in weight pays off massively, saving you thousands in annual rotor and pad replacements by running significantly cooler, season after season.
  • Significantly Longer Lifespan of All Components - The key advantage of our system is its lower overall operating temperature range (650–1050°F) and greater resistance to thermal shocks. In contrast, competitors often run at 1050–1300°F — a range that rapidly accelerates wear across pads, rotors, and fluid. Our thicker, higher-mass rotors also stay below critical cracking temps, unlike thinner, lightweight alternatives that suffer from excessive thermal cycling and stress fractures.
  • Confidence Inspiring - More mass and better heat control mean cooler, more consistent brakes — delivering stable pedal feel and confidence-inspiring performance. The kit, including calipers, DOT-approved stainless steel brake lines, brake pads, and Grade 12.9 hardware, is Made in the USA.
  • Proven Track Setup - The combination of Supra/RX8 12.72"/323mm rotors with Wilwood FSL calipers/BP pads has been a proven reliable solution for the much lighter MR2 for nearly 20 years. Our lightweight 2-piece rotors have so far seen 3+ years of consistent hardcore track racing without needing rotor replacement 
  • Budget Friendly - If you don't need all the bells and whistles, a full front big brake kit can be had for as little as $900 & will last you countless years w/o expensive annual replacements.
  • Free temperature indication changing paint applied on our 2-piece rotors. 

Lightweight - Thanks to modern tech, big brakes no longer mean big weight. Our BBK, featuring flagship 2-piece rotors (aluminum hats + iron discs) and Wilwood Forged Superlite calipers, cuts 22 lbs over stock. But lighter isn’t always better — we chose durability, longevity and performance over shaving every ounce. Thinner rotors may save weight, but they wear faster, run hotter, and need frequent replacement — a tradeoff we refuse to make

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.

Fitment

  • All 1991-1998 Toyota MR2
  • 17" Wheels required

Wheel fitment template

This kit is compatible with most aftermarket wheel setups for the MR2. A minimum wheel diameter of 17 inches is required. For optimal fitment, we recommend wheels with an offset of +32 to +35 or lower (so +17, +22, +30 etc). However, spoke design also plays a significant role, and in some rare cases with +30 or above offset, a 5mm spacer may be necessary. For example, if you plan to run 17x8 +42 for example, you may need a 10mm spacer. To confirm compatibility or if you're unsure, we provide a custom wheel-to-caliper fitment and clearance template specifically designed for this kit. (Front) (Rear)

Confirmed wheel specs that fit

  • Fronts - Enkei RPF1 17x8 +35 and lower offset. Volk Racing TE37 17x9 +22. 
  • Rears - Enkei RPF1 17x9 +35 and lower offset. Volk Racing TE37 17x9 +22.

    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 perfect for 99.9% of users, ideal for street and heavy duty track use, offering a high temperature range (up to 950-1050°F) and minimal to no noise.

    BP20 pads are best suited for dedicated track-only cars, handling sustained temps up to 1200–1250°F. While they deliver top-tier performance, they may squeal loudly when cold. Usable on the street, but not recommended

    Higher temperature pads like BP-30 and BP-40 are race use only.

    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. 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 Technafit 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.
