Interior Rearview Mirrors

An interior mirror shows the driver what is behind through the rear window, without a turn of the head. The panoramic mirror listed here has a black housing and measures 380 mm long by 52 mm high. It takes in more of the rear window and side windows than a standard mirror.

Width is what widens the view. A longer glass covers more of the rear screen and the rear side windows, so a car moving up alongside stays in sight for longer. If the glass is curved, the field widens further but vehicles look smaller and further away, so judge closing speeds with care. A flat glass shows true distances but covers less.

Points to check before fitting:

• Mounting: check how the mirror attaches, and that the original mount is stiff enough to carry the extra width without vibrating at speed.
• View: roll cage tubes, a rear wing or a spare wheel in the rear can block part of the rear screen, so judge the gain in your own car.
• Clearance: the mirror must not block the view through the windscreen or sit where the driver’s head could strike it.

Adjust it from the normal driving position, with the harness done up if one is fitted. Clean the glass with a soft cloth, and check the mounting after events on rough roads.
