PC Brake Disc for OE#99635140501 Front-Left Ventilated

This OE# 99635140501 is a left front ventilated brake disc specifically designed for Porsche models. It is an original equipment part number, signifying Porsche-level excellence in quality and performance.

Exceptional Heat Dissipation Efficiency: As a ventilated disc, it features unique fin-like air channels within its structure. During rotation, these channels effectively pump in air to rapidly dissipate the significant heat generated during braking. This is crucial for high-performance vehicles like Porsche, significantly reducing thermal fade and ensuring consistent braking performance during sustained aggressive driving (e.g., on mountain roads or racetracks).

Front-Wheel Specific Performance: During braking, the vehicle's weight shifts forward, with the front wheels bearing approximately 70% of the braking force. Consequently, the performance of the front brake discs directly determines the vehicle's overall braking efficiency. This ventilated disc is specifically engineered to handle this high-load task.

Professional Installation and Break-in: Porsche's braking system is highly sophisticated and should be installed by a qualified technician. After installation, a gentle break-in period of approximately 300-500 kilometers is required. Avoid sudden braking to ensure optimal matching between the brake pads and rotors.
