Cheap BMW 8 Series Anti Roll Bar

The modern BMW 8 Series (G15 coupé, G14 convertible, G16 Gran Coupé) ran from 2018 onwards as a single generation, so within that generation there is a reasonable chance of compatibility across years — but confirm with the breaker against your exact registration before buying, as suspension components can vary with engine variant and chassis tuning. The earlier E31 8 Series (1989–1999) is an entirely different generation with no parts interchangeability with the modern car. Always quote your reg to the breaker so they can match the correct unit.

Yes, all variants of the modern BMW 8 Series (G14, G15, G16, 2018 onwards) are fitted with anti-roll bars at both the front and rear axle as standard — this applies regardless of engine choice. The E31 8 Series (1989–1999) also carried front and rear anti-roll bars throughout its production run. You'll need to specify whether you want the front or rear bar when requesting quotes from a breaker.

Engine size can influence suspension specification on the 8 Series, as heavier, more powerful variants such as the M850i xDrive may use different bar diameters or rates compared with the 840i. Confirm the exact engine code and drivetrain (rear-wheel drive or xDrive all-wheel drive) with the breaker against your registration, as these details affect which bar is the correct match. Do not assume a bar from a six-cylinder car will be a straight swap onto a V8 or M8 without verification.

Trim level alone does not determine which anti-roll bar you need — an M Sport badge is primarily a cosmetic and interior package on the 8 Series and does not in itself change the anti-roll bar specification. What does matter is the engine variant, drivetrain (RWD or xDrive), and whether the car has optional adaptive suspension or M Sport suspension; confirm any suspension package differences with the breaker against your registration. Focus your search on matching generation, engine, and drivetrain rather than trim name.

No — the front and rear anti-roll bars on the 8 Series are different components with different dimensions and mounting arrangements, so you must specify which end you need when contacting a breaker. Make clear whether you need the NS (nearside/left) or OS (offside/right) drop link or end fitting as well, as these are sided parts. Quoting your registration and the location of the fault will help the breaker pull the right parts quickly.

The G15 coupé and G16 Gran Coupé share the same basic platform but have different wheelbases and body structures, which can affect how suspension components are mounted and sized. There may be some crossover, but this is not guaranteed — route this question directly to the breaker and give them both the donor and recipient registrations so they can check part numbers before you commit to a purchase. Never assume a like-for-like fit across different body styles without verification.
