Brembo 103.9023A Gran Turismo Disc Upgrade Kit for OEM Calipers

The Brembo 103.9023A Gran Turismo Disc Upgrade Kit provides enhanced braking performance by replacing your factory rotors with Brembo's advanced disc assemblies while retaining your original equipment calipers. This disc-only upgrade offers Brembo's proven technology at a cost-effective price point for enthusiasts seeking improved thermal management and stopping power.

Two-Piece Rotor Technology:

Brembo's Gran Turismo two-piece floating hat and rotor design delivers multiple performance advantages. The segmented construction reduces unsprung and rotating weight for improved handling response while accelerating heat dissipation to maintain consistent brake performance during demanding driving conditions.

Key Features:

• Two-piece floating rotor assemblies available in drilled or slotted configurations up to 16 inches (405mm)
• Lightweight hat design reduces rotational mass compared to solid one-piece rotors
• Enhanced thermal capacity prevents brake fade during spirited driving or track use
• Floating rotor attachment allows for thermal expansion without warping
• Designed for use with factory OEM brake calipers
• Fully compatible with ABS and traction control systems
• DOT/TÜV approved components meet stringent safety standards
• Complete hardware included for direct bolt-on installation

This disc upgrade system represents Brembo's commitment to bringing racing-derived technology to street applications. The larger rotor diameter increases brake torque while the two-piece construction provides the thermal management necessary for high-performance driving without the expense of a complete caliper replacement.

Important: Proper wheel fitment verification is critical before installation. Measure your wheels carefully to ensure adequate clearance for the upgraded rotor diameter and caliper assembly.
