No two brake discss are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
The Alfa Romeo 155 was produced from 1992 to 1997 as a single generation, with a facelift arriving around 1995 that brought some exterior and interior changes. The brake disc fitment is more likely to be determined by engine size than by pre- or post-facelift status, but whether discs cross that 1995 boundary without issue is worth confirming with the breaker against your registration before buying.
Yes, engine size is a key factor for brake disc fitment on the 155 — larger-engined variants such as the 2.5 V6 typically ran bigger brakes than smaller-engined versions like the 1.8 or 2.0 Twin Spark. Always tell the breaker your exact engine size so they can match the correct disc diameter and specification. Assuming discs from a different engine variant will swap straight over is not safe.
Trim level on the 155 does not drive brake disc fitment — it is engine size and, for performance variants, the specific mechanical specification that matters. If you are buying from a breaker, focus on matching your engine size rather than trim name. Do be aware that cosmetic differences between donor and your car are irrelevant for discs, since the disc itself is hidden behind the wheel.
These two engines are close in size but the braking systems fitted may differ, and it would be unwise to assume the discs are identical without verification. Give the breaker your registration and engine code so they can cross-reference the exact disc diameter and hub fitment rather than going on engine size alone. Running gear on the 155 does vary with power output even within the four-cylinder range.
No — front and rear brake discs on the 155 are different components with different diameters, and they are not interchangeable. When contacting a breaker, specify clearly whether you need the NS (nearside) or OS (offside) if there is any directional venting to consider, and always state front or rear. Getting this wrong will mean the disc will not fit correctly or safely.
The 155 Q4 used a four-wheel-drive drivetrain and is a distinct mechanical variant, so its brake components should be treated separately from those on the standard front-wheel-drive models. It is very likely the disc sizes and hub specifications differ, so always make the Q4 fitment clear to the breaker and confirm against your registration. Do not assume discs sourced from a standard 155 will cross over to the Q4.
