About Black Diamond

Black Diamond for Porsche

Black Diamond is a British performance brand focused on improving car components in both quality of supply and manufacture. For Porsche applications, the most popular products are Black Diamond performance brake discs, chosen by owners looking for an uprated braking feel and response over standard equipment.

A Quick Look at Black Diamond

Black Diamond information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Black Diamond is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side or axle position, brake system option, and connector or fixing type where relevant.

  • Typical reasons to upgrade include improving brake bite and heat performance when standard pads and discs start to feel inconsistent or show signs of fade.
  • Common symptoms that prompt replacement are brake fade, squeal, glazing, vibration under braking and uneven wear, often made worse by old fluid or sticking calipers.
  • Practical ownership tips include bedding in new pads and discs carefully and renewing old brake fluid to help stabilise pedal feel and performance.
  • If noise is a concern, choose more road-oriented compounds and check product descriptions for any guidance on squeal, dust and suitability for daily use.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the diagnosis and upgrade decision grounded.

Brakes — Brake components are renewed to restore safe stopping power, address wear or upgrade a Porsche for fast road or track-focused use. Common symptoms include vibration, longer stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

Black Diamond Performance Brakes — A focused range of Black Diamond performance discs and pads for Porsche, used where owners want uprated braking bite, better heat control and a more confidence-inspiring pedal for fast-road use compared with standard replacement parts.

Black Diamond Brake Disc DRILLED — Drilled Black Diamond discs offer improved gas evacuation, heat control and a sportier appearance compared with plain discs, helping to maintain consistent pad contact and braking response in demanding road use.

Black Diamond Brake Disc DRILLED & GROOVED — Drilled and grooved Black Diamond discs combine gas venting and pad-surface cleaning to help reduce fade, glazing and uneven transfer layers, aimed at drivers who regularly use their Porsche in more demanding conditions.

Performance Brake Hoses — Braided performance brake hoses are used to replace ageing rubber lines that can swell, crack or balloon, helping to restore a firmer pedal feel, improve response and reduce the sponginess associated with hose expansion.
