Hella Pagid 355132331 Vented Brake Rotor, 330mm 5x112

If you're chasing a brake refresh on a European car with the 5x112 bolt pattern, this Hella Pagid disc is the kind of part you bolt on and forget about. It's a rotor measuring 330mm across, vented, and cast as a single one-piece unit. That 5x112 pattern shows up on a lot of Audi, Volkswagen, and Mercedes models, along with newer BMWs, so it covers a wide slice of the German-car world. Check your existing rotor's diameter and your caliper before you order, because 330mm is a specific size and it has to match the bracket you're bolting into.

The vented design is the important bit here. A vented rotor has two friction faces with cooling vanes cast between them, and that gap lets air move through the disc while you drive. Brakes turn motion into heat, and a lot of it. On a heavier car or during repeated hard stops coming down a grade, a solid disc can soak up more heat than it can shed, and that's when you start feeling fade or a pulsing pedal. The vanes in this 330mm disc give the heat somewhere to go, so the rotor runs cooler and stays flatter over its life.

Hella Pagid casts this one from gray cast iron and finishes it with a zinc coating. If you've ever pulled a wheel off a car that sat through a wet winter, you know the story. The swept braking surface stays shiny but the hat, the edges, and the vanes bloom with orange rust in a matter of weeks. The zinc coat fights that. It keeps the non-friction areas looking clean and, more to the point, slows the corrosion that eats away at a bare casting over the years. Behind an open wheel, it just looks right, too.

Let's talk numbers, because fitment on a brake rotor is all about the numbers. This disc is 330mm in diameter, 32mm thick across the friction faces, and 59.5mm tall from the mounting face to the top of the hat. The center bore, the hub diameter, is 67mm. Every one of those has to line up with your car. The 32mm thickness is your new, full-spec measurement, and every rotor has a minimum thickness stamped on it that you should never machine or wear past. The 67mm hub and 5x112 pattern determine whether it seats on your hub at all. When in doubt, measure the disc that's coming off and match it.

Installation is standard fare for anyone who's done a brake job. You'll pull the caliper and carrier, slide the old rotor off, clean the hub face down to bare metal so the new disc seats flat, and torque everything back to your car's spec. One tip worth repeating, wipe the friction faces with brake cleaner before you fit the pads. The zinc coating on the swept face burns off in the first few stops on its own, but a quick clean means a consistent bite from the start.

This is sold as a single rotor, and almost nobody should replace just one. Brakes work in axle pairs, and a fresh disc on one side with a worn, thinner disc on the other gives you uneven braking and a car that pulls under hard stops. Order two for the axle you're doing, and it's smart to fit new pads at the same time, since old pads have worn to the shape of the old rotor. Do the job once, do it as a set, and you're good for a long stretch.

Hella Pagid builds these to original-equipment fitment standards, which is the whole point of a one-piece design like this. No assembly, no floating hardware to rattle loose, just a solid casting that drops into the spot the factory disc came out of. For a daily-driven European car, that's exactly what you want under the wheel.
