Toyota GT86 GR86 Subaru BRZ Performance brake system front + rear
Toyota GT86 (ZN6) and GR86 (ZN8) platforms, performance brake upgrades range from “factory plus” Brembo setups to full motorsport-grade Big Brake Kits (BBK). Since the chassis architecture is nearly identical between generations, most systems are cross-compatible, though wheel clearance varies.
1. OEM Performance Options (Brembo)
If you are looking for an “original” upgrade, the most common route is the Performance Pack Brembo system found on the GT86 TRD or BRZ tS.
-
Front: 4-piston aluminum monoblock calipers with 326x30mm rotors.
-
Rear: 2-piston calipers with 316x20mm rotors.
-
Availability: Can be sourced as a complete used set or via “Retrofit Kits” that include the necessary brackets to adapt these to base models.
-
Note: These generally require at least 17-inch wheels with specific “Brembo-clearing” spoke designs (OEM 17″ non-performance wheels usually require spacers).
2. Aftermarket Performance Systems
For dedicated track use or high-horsepower builds, these front and rear matched sets are the industry standards:
| Brand | System Type | Key Specifications | Use Case |
| AP Racing | Radi-CAL / Pro5000R | Front: 4 or 6-Pot / Rear: 4-Pot | Pure Track / Racing. Extremely lightweight; high heat dissipation. |
| Wilwood | Superlite 6R/4R | Front: 6-Pot (328mm) / Rear: 4-Pot | Performance Street / Light Track. Cost-effective and wide pad choice. |
| Brembo | GT / GT-S Systems | Front: 6-Pot (355mm) / Rear: 4-Pot | Luxury Performance. High-end finish; excellent pedal modulation. |
| EBC Brakes | Apollo Series | Front: 4-Pot (330mm) | Balanced Street/Track. Two-piece bolted design for stiffness. |
3. Critical Compatibility Notes
-
Parking Brake: When upgrading the rear system, ensure the kit is designed to retain the internal drum-style parking brake. Most major kits (Wilwood, AP Racing by Essex, Brembo) include a custom rotor “hat” that keeps the handbrake functional.
-
Master Cylinder: The GR86/GT86 master cylinder is well-matched for 4-piston front upgrades. If moving to a very large 6-piston front/4-piston rear setup, ensure the piston surface area is balanced to prevent a “mushy” pedal.
-
Wheel Clearance: * 17″ Wheels: Fit most 299mm to 325mm kits (e.g., AP Racing Sprint, Wilwood).
-
18″ Wheels: Generally required for 350mm+ “Big Brake” kits.
-
4. Support Components
To maximize any performance brake system, these additions are highly recommended:
-
Stainless Steel Braided Lines: Reduces hose expansion for a firmer pedal.
-
Brake Master Cylinder Brace: Prevents firewall flex under heavy braking (highly effective on the ZN6/ZN8 chassis).
-
High-Temp Fluid: DOT 4 racing fluid (e.g., Motul RBF660 or Castrol SRF).
