Paragon Performance Brakes for Subaru BRZ, Toyota 86 & GR86

1-Piece Cast Rotors — Same Technology, Lower Cost

Paragon's 1-piece cast rotors use the same high-carbon cast iron metallurgy, heat treatment and friction ring design as their 2-piece range — just cast as a single-piece rotor with an integrated hat. You get the Paragon iron quality and the straight-groove slot pattern that improves cold bite and pad-gas evacuation, without the cost of the aluminium centre hat and floating hardware. For BRZ/86/GR86 owners who want a meaningful rotor upgrade over OEM without the jump to a full 2-piece, this is the right starting point. Direct bolt-on to factory calipers — same thickness, same diameter, same bolt pattern.

2-Piece Rotors — Weight Reduction & Thermal Isolation

Same friction ring metallurgy as the 1-piece, bolted to a CNC-machined aluminium centre hat with stainless floating hardware. Typically 3–4kg lighter per corner than OEM — significant on a car that only weighs ~1,300kg to begin with. The aluminium hat insulates the wheel bearing from rotor heat, and the replaceable friction ring design means you only replace the ring, not the complete rotor, at service intervals. Straight-groove slot pattern as standard. The right upgrade for a serious road/track BRZ/86/GR86 build.

PA055 Front Big Brake Kit

4-piston forged monoblock front caliper paired with Paragon 2-piece rotors. The PA055 is purpose-built for platforms like the BRZ/86/GR86 — lighter and more compact than the PA015 6-piston, with fitment under 17" wheels where space is tight. Massive improvement in pad area and rotor diameter over the factory single-piston caliper, without adding the weight penalty of an oversized BBK on a light-weight chassis.

PA025 Rear Big Brake Kit

4-piston forged rear caliper with 2-piece rotor. Designed to balance a front PA055 setup — when you upgrade front braking capacity, you eventually need to upgrade the rear to maintain the correct brake bias. Particularly important on a rear-drive chassis like the BRZ/86/GR86 where rear brake performance contributes meaningfully to stability under trail braking.

PA015 / PA035 Front Big Brake Kit

6-piston forged monoblock caliper on 355–380mm 2-piece rotors. Overkill for a street-driven BRZ, but the right answer for a serious time attack car, particularly on turbocharged builds where power has been substantially increased over stock. Requires 18"+ wheels.

1st Gen Subaru BRZ & Toyota 86 / Scion FR-S (2012–2021, ZC6 / ZN6)

The original 2012+ chassis — naturally aspirated FA20 2.0L, 147kW. Factory brakes are modest: 294mm front rotors with single-piston sliding calipers on most variants, stepping up to Brembo 4-pots on the later Performance Pack cars. Paragon 1-piece cast and 2-piece rotors fit the standard caliper; the PA055 front BBK and PA025 rear BBK are direct bolt-on upgrades that transform the braking capability of the chassis. This generation is the most tracked BRZ/86 in Australia, and it's where the majority of Paragon sales concentrate.

2nd Gen Subaru BRZ & Toyota GR86 (2022+, ZD8 / ZN8)

The second-generation chassis — FA24 2.4L, 174kW, better torque delivery and a stiffer chassis than the original. Factory brakes are larger than the first gen but still benefit from the same upgrade path. Paragon rotors and BBK packages for the ZD8/ZN8 are fitment-specific — the rotor diameter and caliper mounting changed between generations, so make sure you're ordering for the correct model year.

Performance Pack / Brembo-Equipped Cars

The later 1st-gen Performance Pack BRZs and 86s came with factory Brembo 4-piston front calipers. Paragon 2-piece rotors are specifically engineered for this caliper fitment and are the best-value upgrade for PP-equipped cars — you keep the capable factory caliper, add weight reduction and serviceable construction, and unlock meaningful track performance.

Street-Driven BRZ / 86 / GR86 — Entry Rotor Upgrade

If your factory rotors are worn, grooved or warped and you want a genuine upgrade without the cost of a 2-piece, Paragon 1-piece cast rotors with a street pad (DIXCEL M Type for low dust, DIXCEL Z Type for spirited driving) is the right call. Keeps the factory caliper, factory lines, factory brake bias — just better rotors with better iron.

Daily Driven with Weekend Track Use

Step up to Paragon 2-piece rotors. On a 1,300kg chassis, 3–4kg off each corner is felt immediately in steering response and turn-in. Pair with a DIXCEL Z or ES compound pad — this is the most popular BRZ/86/GR86 track-day setup in Australia because it works and it lasts.

Dedicated Track Car — Front & Rear BBK

If you're doing multiple track days per month or running in time attack, the PA055 front + PA025 rear BBK package is the sweet spot for the BRZ/86/GR86. You gain rotor diameter, pad area and thermal capacity without adding the weight of an oversized 6-piston caliper that a naturally aspirated 1,300kg car doesn't need. Paired with a track-compound pad (DIXCEL RE or Specom) and high-temperature fluid, this setup handles back-to-back 20-minute sessions without fade.

Turbocharged / Time Attack Build

If you've turbocharged the FA20/FA24 or you're running 300kW+ on a dedicated competition build, step up to the PA015/PA035 6-piston front BBK with PA025 rear. More power means more speed into braking zones, which means more thermal load — at this point, the larger rotor and pad area of the 6-piston caliper pays back clearly.

Three reasons Paragon suits this platform specifically:

• Weight matters most on a light car — the BRZ/86/GR86's whole appeal is its lightness. Adding heavy BBK hardware undermines the chassis balance that makes the car great in the first place. Paragon's approach — forged monoblock calipers on aluminium-hatted 2-piece rotors — keeps unsprung mass down where it matters.
• Brake bias is critical on a rear-drive chassis — upgrade the front only and you push the balance forward, losing rear stability under trail braking. The PA025 rear BBK exists specifically to maintain balance when the front i
