For anyone who's spent time behind the wheel of a Ferrari 308, you know that the stock brakes can leave a bit to be desired, especially when you're pushing the limits. That’s where the Girodisc lightweight brake system comes into play. This isn’t just a simple upgrade; it’s a complete overhaul that really transforms your driving experience.

The Girodisc setup replaces the OE front rotor and caliper, as well as the rear rotor, and it’s designed to bolt right on without any hassle. You’ll notice a significant reduction in weight and an impressive resistance to brake fade, which is crucial when you’re out on the track or just enjoying a spirited drive on winding roads. The front caliper is a forged aluminum Wilwood racing caliper with four pistons, complete with dirt seals for those rainy days. Pair that with a two-piece aluminum hat and iron rotor sized at 310 x 25 mm, and you’ve got a serious upgrade.

Now, for the rear rotor, it’s a direct replacement that works with the original caliper, keeping your parking brake intact. It’s also a floating two-piece design, which helps with heat management. You’ll get specific braided stainless steel brake lines over Teflon included in the kit, along with the right pads that balance the whole system perfectly.

One of the standout features of the Girodisc system is how well it maintains the braking balance of the OE setup, but with a noticeable boost in braking torque and thermal capacity. You can hit the track hard without worrying about losing pedal feel or experiencing fade. The caliper piston sizing is spot on, closely mirroring the OE master cylinder and hydraulics, ensuring a smooth and responsive braking experience.

And here’s a nice little bonus: this system fits right inside your 16-inch Ferrari 308 wheels, so there’s no need to shell out for larger rims. That’s a win-win!

Let’s talk numbers. The Girodisc front brake system, calipers included, weighs in at 15.8 pounds lighter than the factory setup. The front discs are not only larger at 36 mm but also 3.3 pounds lighter. The Wilwood forged aluminum caliper shaves off another 4.6 pounds compared to the stock iron caliper. Even the rear discs drop more than 3 pounds, offering a 36.4% improvement in surface area-to-weight ratio compared to the OE version. Less weight means less rotational inertia and reduced unsprung mass, which is a game-changer for handling.

In terms of performance, the front caliper is made from flow-forged aluminum, chosen for its lightweight and correct piston sizing. It’s a proven racing component, and the road-ready dirt seals ensure you’re covered no matter the conditions. The two-piece rotor design is a smart move, allowing for the different expansion rates of the hat and rotor, so you won’t have to worry about warping. Plus, the floating mount system with high-strength alloy steel drive pins helps the rotor self-center between the pads, while anti-noise springs keep things quiet when it’s cold. Those thirty-two directionally curved vanes in the rotor? They act like a little centrifugal air pump, moving cooling air through the rotor as it spins, which helps shed heat and minimizes brake pad fade. The stock rotors just can’t compete with that.

Girodisc doesn’t skimp on materials, either. The rotors are made from high carbon content iron for durability and stable thermal performance, and they come with zinc plating to resist corrosion. The top hat is crafted from aircraft-grade 6061 T-6 billet aluminum and given a sleek gun-metal anodized finish. The hardware is top-notch too, with cadmium plated alloy steel drive bushings that handle the braking load while maintaining float, and Grade 12 cap screws that keep everything snug without rattling.

To keep the braking balance dialed in, Girodisc uses BP-10 front pads and Ferodo DS2500 rear pads. It’s all about that perfect harmony between stopping power and control.

So, if you’re ready to take your Ferrari 308 to the next level, this Girodisc brake system is a no-brainer. It’s built for performance, durability, and a whole lot of fun on the road or the track.
