If you're looking to enhance your Ferrari 308 without going overboard, the Girodisc lightweight brake system is a solid choice. It’s designed as a direct replacement for the stock front rotor and caliper, as well as the rear rotor. Installation? A breeze—it's a bolt-on setup that delivers some serious performance benefits, especially in terms of weight and brake fade resistance.

Let’s talk specifics: the front caliper is a forged aluminum four-piston Wilwood racing caliper, complete with dirt seals for those of us who actually drive our cars on the road. The front rotor measures in at a robust 310 x 25 mm and features a two-piece aluminum hat paired with an iron rotor. The rear rotor is a direct swap for the OE rotor and keeps the original caliper, so you won’t lose your parking brake functionality. Plus, it’s a floating two-piece design, which is a nice touch.

One of the standout features of the Girodisc system is its design for balanced braking. It matches the OE system's balance while cranking up the braking torque, thermal capacity, and cooling rate at every corner. You’ll notice a firmer pedal feel and better modulation, which is a game changer during those spirited drives or track days—no more worrying about brake fade or losing pedal feel when you’re pushing the limits.

And here’s a perk that’s hard to ignore: this system fits right into your existing 16-inch Ferrari 308 wheels. No need to shell out for bigger rims, which is a relief for those of us trying to keep costs in check.

Now, let’s get into the numbers. The complete front brake system, calipers included, weighs a whopping 15.8 lbs less than the stock setup. The front discs are 3.3 lbs lighter, even though they’re 36 mm larger. The Wilwood caliper itself is 4.6 lbs lighter than the original iron caliper. On the rear, the discs are over 3 lbs lighter than stock, and you get a 36.4% improvement in surface area-to-weight ratio compared to the OE rotors. This lighter setup significantly reduces rotational inertia and unsprung mass, which is a win for handling and performance.

Braking performance is top-notch, too. The front caliper is flow-forged aluminum, chosen for its lightweight properties and optimal piston sizing. Those dirt seals are a nice touch for road use. The rotor’s two-piece design is a racing-inspired feature that helps prevent warping by accommodating different expansion rates between the hat and rotor. With a floating mount system using high-strength alloy steel drive pins, you get both axial and radial float. Anti-noise springs keep things quiet when it’s cold, and the thirty-two directionally curved vanes act like a centrifugal air pump, pushing cooling air through the rotor to keep things cool and reduce fading.

Girodisc doesn’t cut corners when it comes to materials, either. The rotors are made from high carbon content iron for durability and thermal stability, with a zinc plating to fend off corrosion. The top hat is crafted from aircraft-grade 6061 T-6 billet aluminum and features a sleek gun-metal anodized finish. The assembly hardware consists of cadmium plated alloy steel drive bushings and grade 12 cap screws, ensuring everything stays secure and rattle-free while you’re on the road.

For pads, Girodisc pairs BP-10 fronts with Ferodo DS2500 rears to maintain a balanced braking feel throughout the system.

In short, if you’re serious about improving your Ferrari 308’s braking performance, the Girodisc brake system is worth a look. It’s built for enthusiasts who appreciate quality and performance without sacrificing the joy of driving.
