The Nissan 350Z and Infiniti G35's nose is fairly restrictive, which can prevent the brakes from getting enough airflow to adequately cool themselves, resulting in infamous brake fade issues on the 350Z and G35. Brake fade at the wrong place and time could potentially result in a crash, so it’s important to address this problem before any track day or hard canyon run.
The airflow problem on the 350Z is enough of an issue that even high performance brake rotors, pads and fluid don't help that much on their own without adequate airflow, which is what led us to develop this MUCH NEEDED brake cooling duct kit.
These 350Z and G35 brake cooling duct kits can be used with Stillen Sport Rotors and Metal Matrix brake pads, AP Racing Brake Kits, and factory brake systems.
Made using the same high-heat motorsports-grade ducting used on founder Steve Millen's #75 Nissan 300ZX Race Car, this kit is of quality you couldn't replicate yourself at the hardware store. The STILLEN 350Z and G35 brake cooling kit is composed of several pieces, designed specifically for the punishing conditions that may result from high performance vehicles. The kit comes in two varieties depending on whether the vehicle is equipped with the STILLEN Polyurethane Front Fascia or the standard factory fascia. Both kits feature 6-foot silicon rubber air duct hose, lined with a cylindrical brass covered steel braiding.
To test the performance of the STILLEN Brake Cooling Kit, our engineers pushed the kit to the limit at the Auto Club Speedway in Fontana, California. Testing was performed with the brake cooling kit connected on one side, and not the other. Thermo-couplers were installed on the inboard friction surface of the rotors and connected to professional, race grade, data logging equipment. This testing environment ensured accurate readings under identical testing conditions. During testing the non-cooled rotors reached 600 degrees while the cooled side only reached 456 degrees. This is a temperature difference of over 140 degrees or 25%. The Brake Cooling Kit outperformed our expectations, and decreased rotor temperatures by 25% from side to side. The cooling kit spent a good amount of time with STILLEN's engineers, and the results are a testament to their dedication and hard work. Testing showed not only does this kit keep the brakes cooler, but it better manages the temperature keeping the rotors at a more consistent temperature thus reducing the thermal cycling of the rotor.
The ducting takes advantage of airflow from the front of the vehicle, either by mating to the specifically-designed STILLEN Fascia with the established brake ducting scoops, or with the factory fascia via a 304 stainless steel CNC laser cut bracket that is bolted onto the OEM fascia. On the hub side, another 304 stainless steel CNC laser cut bracket formed on a 7-axis CNC machine is provided to brace the hose in a position that precisely leads the incoming airflow to the center of the rotor. This location directs the cool air into the center of the rotor blowing through the vented portion of the disc. This is the optimal location for brake rotor cooling ducts as it is the only way to cool the entire rotor from the inside out.

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.
With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
