Accuracy note: genuinely worth knowing — Corsa-D owners have directly reported conflicting disc sizes showing up for the same car on parts retailer websites (257mm and 284mm both listed for a 1.3 CDTI), with the general advice being to physically measure your existing disc rather than trust the site's suggestion alone.

Corsa E, standard trims	Front: 257-266mm diameter, vented. Rear: 264mm diameter, solid, 10mm thickness, 8mm minimum
Corsa D/E VXR/OPC performance models	Front: 308mm diameter, vented, 25mm thickness, 22mm minimum. Rear: 264mm diameter, solid, 10mm thickness, 8mm minimum
Genuine Vauxhall part reference (older Corsa, shared with Meriva/Combo)	Vauxhall OEM: 93186303 (also referenced as 93175376, 93176115) — 280mm front disc and pad set
Important	If two different sizes both appear to match your reg, measure the actual disc currently fitted rather than guessing, since online lookups can list multiple genuine factory variants for the same model and engine.

The Part That Pads Depend On

Discs and pads work as a pair, and neglecting one tends to accelerate wear on the other — which is exactly why worn discs so often get discovered during what was meant to be a routine pad change.

Before you buy: disc size and design vary by trim, engine size and whether your car has the standard or "sport" brake package. Always confirm against your VIN before ordering.

What They Do

Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the Corsa typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
