Yes, the front and rear track is about 24 mm wider for the Granada front and rear. There are quite a few different numbers around on the internet, so it's difficult to say what is really correct. In the end the track also depends on the offset of the wheels, and those might be different as well for the Sierra and Granada.


The reason for the wider rear track is the thicker flanges on the arms. The rest of the arms is exactly the same as on the Sierra.


With longer arms I meant the TCAs on the front suspension, making the front track wider than the Sierra.
