Genuine Subaru STi Rear Brembo Caliper Mounting Bolt (M10x27) - 901120102

Secure your rear Brembo calipers with 100% Genuine Subaru high-tensile hardware.

The Subaru Rear Caliper Mounting Bolt (901120102) is the factory-spec fastener required to secure your 2-pot rear Brembo calipers to the hub. Unlike standard hardware, these bolts are engineered to handle the extreme thermal expansion and shear forces generated during high-performance braking.

Whether you are performing a seasonal fluid flush or a complete caliper restoration, replacing "crusty" or over-torqued hardware is essential for maintaining the structural integrity of your STi’s braking system.

Why "New Bolts" Are Non-Negotiable

• Prevent Stretching: These bolts are subject to high torque loads; reusing stretched bolts risks failure or stripped threads in your expensive aluminum calipers.

• Corrosion Resistance: Features the correct factory coating to prevent the galvanic corrosion common when steel bolts meet aluminum caliper housings.

• Exact Fitment: Sourced through the Subaru Japan parts network to ensure the precise M10 x 1.5mm pitch and 27mm length required for a flush, secure fit.
