If you're looking to upgrade your braking game, the Girodisc system is a solid choice. This isn't just any rotor; it's a direct swap for the factory disc on your BMW E9X 335i, meaning you won't need to mess around with any modifications. Just bolt it right on and get back to driving.
What sets these rotors apart? For starters, the central hat is crafted from high-quality 6061-T6 aluminum, sourced right here in the U.S. That’s not just for looks; it’s lightweight and tough, giving you the durability you need without adding unnecessary weight. The rotor itself is made from Girodisc's proprietary cast iron, which is poured and machined in-house. You can count on that quality control.
Now, let’s talk about cooling. These rotors feature a curved vane design that’s straight out of the racing world. It’s engineered to act like a centrifugal pump, pushing cooling air through the disc. This means better performance and less fade when you're really putting the pedal to the metal.
One of the cool features here is the floating mount system. It uses 10 high-strength alloy steel drive pins, also made in the USA, and they’re cadmium plated for long-lasting corrosion resistance. These pins handle the load during braking while allowing the rotor and hat to float a bit. This design helps keep everything centered and reduces noise—no one wants a rattling rotor, right? Plus, those anti-noise spring washers are a nice touch, letting the rotor expand with heat without making a racket.
