Understanding Fitment: Why Year and Trim Matter

It's tempting to assume that if a part fits a 2018 Q50, it'll fit a 2020 Q50 too. Sometimes that's true, but mid-cycle refreshes and trim-specific hardware mean it isn't guaranteed.

Red Sport 400 models, for example, often use different brake rotors and turbo hardware than standard trims, even within the same model year, because of the added power output.

Suspension components can also change between years as manufacturers update bushings, mounting points, or materials.

That's why every part in our catalog lists exact make, model, year range, and trim compatibility. When in doubt, use the fitment filter or send us your VIN and we'll confirm before you order.
