Brembo Xtra brake discs are a drilled-disc option designed for drivers who want an alternative to a standard plain braking surface while retaining an application-specific replacement disc. The important part when buying them is still fitment: an Xtra disc must match the exact vehicle, axle and brake package.
Brembo describes its Xtra discs as drilled, with holes in the braking surface that help manage gases and heat and maintain braking response. Brembo also lists Xtra as a road-use and sports-driving line. Individual part numbers have their own dimensions and application data, so the Xtra name does not mean one disc fits every version of a vehicle.
What makes a Brembo Xtra disc different?
The most obvious difference is the drilled braking surface. Depending on the individual part number, Brembo also lists features such as UV coating, high-carbon material or specific ventilation technologies. Those features vary by disc, so use the specification for the exact Brembo reference rather than assuming every Xtra part has identical construction.
Brembo Xtra part numbers
Many Xtra references use an X suffix in the part number, but the safest approach is to search the complete Brembo number shown in the catalogue or on the listing. If a reference has been superseded, confirm the new number and application rather than changing only the suffix yourself.
What dimensions should I check?
| Specification | What to compare |
|---|---|
| Diameter | Exact outer diameter in millimetres |
| Thickness | New disc thickness for the correct brake package |
| Height | Disc profile/offset on the hub |
| Centre bore | Hub locating diameter |
| Hole count | Wheel-hub and retaining arrangement |
| Disc type | Solid or vented, depending on application |
| Axle | Front or rear |
Our brake disc dimensions guide explains these measurements in more detail.
Are all Brembo Xtra discs vented?
No. Brembo's catalogue includes both vented and solid Xtra references depending on the vehicle and axle. That is another reason not to buy from the drilled appearance alone.
Do drilled discs need different brake pads?
The correct brake pad is determined by the vehicle's caliper and braking application. Do not choose a pad just because the disc is drilled. Check the catalogued pad reference for the same vehicle and brake system. If buying a combined disc-and-pad kit, confirm that both components are matched to the application.
Brembo Xtra vs a standard plain disc
A standard replacement disc is intended to reproduce the required braking dimensions and basic construction for the application. Xtra adds the drilled surface and is positioned by Brembo as a sportier road-use option. The right choice depends on the correct fitment first, then the type of disc you want within that application.
Can I fit Xtra discs only on the front?
If Brembo catalogues an Xtra reference for the front axle of your exact vehicle, it can be selected for that axle without assuming the rear must use the same surface style. What is available front and rear depends on the vehicle. Always follow the product and vehicle application data.
How to buy the correct Brembo Xtra discs
- Select the exact vehicle and engine.
- Confirm front or rear axle.
- Compare the complete Brembo part number.
- Check diameter, thickness, height, centre bore and disc type.
- Read production-date, chassis or brake-system notes.
- Confirm how many discs the listing supplies.
- If there is more than one option, use the OE reference or ask for a fitment check.
Brembo Xtra FAQs
Does “Xtra” mean the disc is drilled?
For Brembo's Xtra disc line, the defining surface feature is drilled holes. Individual references can have additional features stated in Brembo's catalogue.
Does a drilled disc fit if the diameter matches?
No. Diameter is only one measurement. Thickness, height, centre bore, mounting layout and axle application must also match.
Can I search by Brembo part number?
Yes. Enter the complete manufacturer reference into our search, then confirm the vehicle notes and dimensions shown on the product page.
