What This Product Does

The support forms the mounting base for the front registration plate. It is a number plate mounting component.

Functions

  • Supports the registration plate at the front of the vehicle.
  • Replaces an absent or damaged support within the mounting arrangement.


Technical Details

  • OE Match product identification: 91170105300/8; associated comparison reference: 91150521901. ()

Symptoms of Fault

Check the support and its fixings when the plate moves, rattles or appears misaligned. Damaged screw locations or a visibly distorted support also warrant inspection; loose fasteners can cause similar symptoms.


Why Replacement Matters

Replacing a broken or missing support restores the plate mounting arrangement. Inspect adjacent attachment points before installation so that worn or damaged fixings are not overlooked.

Before ordering, confirm compatibility against your vehicle's model, production year, engine and existing mounting arrangement.

Most automobiles come from the factory without the provisions for front license plates due to the fact that many states and countries do not require a front plate.The last thing you want to do is drill holes in your very expensive bumper cover just to mount that ugly front tag. Rennline’s billet license plate mount eliminates the need to drill and allows you to easily remove your plate for shows, track events or anytime it is not needed. This design allows you to adjust your plates location by height, width and angle. Unlike any other designs on the market, we have engineered this system to be easily removed from the car without first removing your license plate and plate frame. All components are stainless, powder coated or anodized to withstand daily driving conditions.
