Wilwood Big Brake Kit for 2003 Porsche 911

IMPORTANT: Most Wilwood Big Brake Kits will require the use of larger than factory wheels. Please ensure to check the recommended wheel size in the More Info notes for your application. Also, some kits will require Wilwood brake lines and some rear kits special parking brake cables. The Wilwood install instructions will provide details on these, if required. Please contact us if you need to order Wilwood brake lines or cables.

Wilwood had been regarded as one of the top performing brake upgrade companies for decades, and their Big Brake Kits carry this legacy with repeatable performance and great looks. Offered in a 4-Piston or 6-Piston upgrade (depending on the application), these Wilwood Big Brake Kits are capable of handling extreme conditions at the track, or provide reliable stopping power for your daily driven Porsche 911.

Each kit is engineered to be a complete bolt-on solution, and designed to work on an otherwise stock vehicle, making installation a breeze. Wilwood takes great care in the implementation of their big brake kits, and takes the factory hydraulic brake system into account to ensure proper brake bias. Included with the kits are their 4 or 6-Piston Brake Calipers, Caliper Mounting Brackets, 2-Piece Rotors, BP-10 Brake Pads, and all of the necessary mounting hardware/brackets. All of this makes a Wilwood Big Brake Kit a great option for your Porsche 911, and is sure to suit your build given the versatile options available.

The standard street-oriented calipers come with a powdercoat finish, which provides excellent protection and is resistant against stains caused by brake fluid or brake dust. The BP-10 brake pads are part of Wilwood's "Smart Pads" lineup and feature a medium friction blend that wont tear up your rotors, as well as keep dust and noise at a minimum.

Race Calipers: On some applications, Wilwood also provides the option of Race Calipers, which come with Mil-Spec hard anodized calipers with hardcore BP-30 race formula brake pads, which are also part of Wilwood's "Smart Pads" lineup.
