Brembo Engineering, through its official partner Race Technologies, rejects 2002+ WRX STI OE calipers on BRZ/FR-S/GT86 because mounting position, crossover/bleeding, staggered-piston order, piston sizing, brake bias and ABS behavior differ. Use a chassis-designed complete system and verify wheel clearance, rotor, pads, lines, master-cylinder/bias and rear balance.
OEM numbers
Education/systems page rather than one part number. Factory-correct reference is the first-generation BRZ Performance Package four-piston front/two-piston rear Brembo system. Checked complete new Formula S 48-piece PP-style kit included calipers, pads, lines, shields, pins, clips and hardware. WRX STI OE calipers are not presented as compatible.Supersession
No supersession. Factory Performance Package, Brembo GT systems and WRX STI OE calipers are different brake systems. Do not treat visual similarity as interchange.
Fitment
Brembo Engineering, through its official partner Race Technologies, rejects 2002+ WRX STI OE calipers on BRZ/FR-S/GT86 because mounting position, crossover/bleeding, staggered-piston order, piston sizing, brake bias and ABS behavior differ. Use a chassis-designed complete system and verify wheel clearance, rotor, pads, lines, master-cylinder/bias and rear balance.
Aftermarket options
Checked factory Performance Package-style complete kit and chassis-specific Brembo GT system. Both checked examples were sold out. Budget bracket conversions were not promoted because a complete current engineering/fitment audit was not available in this pass.
Before you buy
WRX STI OE Brembos are not an approved crossover for this chassis. Both checked chassis-specific complete systems were sold out. Brake-system changes require matched front/rear components, correct bleeding, wheel clearance and professional bias/ABS consideration. Seller-depth exception: Complete first-generation Brembo systems are scarce; two major exact paths were sold out. Do not pad the seller count with the technical blog or generic Brembo catalog.
