BMW E30 4-hole solid brake disc - Bosch 0 986 478 563, 257.7mm, oiled surface

For E30s that see fast road use, track days or just need a no-nonsense, true-running rotor: this is the Bosch 0 986 478 563 solid disc. Not drilled. Not slotted. Not fancy. Just precision-ground, oiled-surface iron - the same spec fitted to many late-’80s E30s from the factory.

• E30-specific: 4-bolt pattern, 257.7 mm diameter, 9.9 mm nominal thickness - fits all standard E30 front hubs (no M3 or aftermarket hub adapters)
• Search terms covered: E30 solid brake disc, E30 oiled rotor, BMW 3 Series E30 brake disc, 257.7 mm brake disc, 4 hole brake disc, E30 front brake disc, E30 daily driver brake disc
• No corrosion-prone bare cast iron - the light oil coating resists surface rust in UK garages and damp sheds
• Compatible with OEM-spec and most stage 1 fast road pad compounds (e.g. Ferodo DS2500, EBC Redstuff, Pagid RS29)

Because race car.
