This is a comprehensive guide on how to install 4D number plates on to your vehicle. These stylish and modern plates are a fantastic way to enhance the look of your car, but proper installation is crucial to ensure they are secure and visible. The last thing you want is your number plates falling off!
In this guide, we will walk you through the entire process, from preparing your vehicle and gathering the necessary tools, to the step-by-step installation process and post-installation maintenance.
Whether you’re a seasoned car enthusiast or a beginner, this guide will provide you with all the information you need to your 4D license plates successfully.
Preparing Your Vehicle for 4D Number Plate Installation
Before you begin the installation of your new 4D number plates, it’s important to prepare your vehicle properly. Start by removing your old number plates if they’re still attached. Be careful not to damage the mounting area or the paintwork of your vehicle.
If they’re held on with sticky pads, gently prise them away until they lift completely, applying only as much force as needed.
Once the old plates are removed, clean the area thoroughly. Use a mild soap or detergent and warm water to remove any dirt or residue left on the vehicle. Dry the area completely before proceeding with the installation.
Next, gather all the tools and equipment you’ll need for the installation. Having everything at hand will make the process smoother and quicker. It’s also a good idea to check the condition of the mounting area for damage or irregularities, as these should be addressed before installing the new plates. This will ensure a secure fit and prevent any potential issues down the line.
The Tools and Equipment You’ll Need
Installation of 4D number plates does not require any special tools. You’ll need a Pozidriv screwdriver that fits the screws provided. We typically provide 6 or 8 gauge, 1” screws.
You will also need a drill to create the holes in your new plates and a 4 mm bit.
In addition to screws, we provide self-adhesive strips (sticky pads) with each order. These can be used to secure the plates further and prevent any movement or vibration while driving and to act as padding between the vehicle surface and the plates.
It’s also a good idea to have a level on hand to ensure that the plates are installed straight.
Step-by-Step Guide to Installing 4D Number Plates
1. Mark Your Hole Positions
If your old plates were fixed to the vehicle using screws, start by lining the old plates up on top of your new ones. Line them up so they are facing away from you and mark the hole positions on the back of the plates, not the front.
If your old plates were affixed using sticky pads, you will need to measure the distance between the screw holes on your vehicle and then mark those positions on the plates, again on the backs.
2. Drilling
You’ll drill one plate at a time – don’t attempt to drill through both at once. Place the first plate on a surface suitable for drilling and hold firmly while drilling. Ensure you drill straight as acrylic can crack easily due to its brittleness.
⚠ Never try to drive a screw directly into an acrylic number plate. This can cause shattering or breaking – you must drill the holes first.
Drill at a constant rate of at least 400 rpm and press firmly down onto the plates. Remember to drill through the back and come out the front. Don’t go through the front as this can cause delamination of the reflective backing film as the bit pushes through. Be careful not to keep pushing once the bit goes through as you don’t want the chuck causing any damage to the back of the plate.
3. Affixing Front & Rear 4D Registration Plates
Rear plate
Now the hole positions are drilled, it’s time to affix the plates to your vehicle.
The rear end of most cars has pre-positioned mounting holes that cannot be changed. It’s important that your drill holes match these mounting holes.
Place one screw into a screw cap of the appropriate colour and push it through one of the holes. Screw it down until it’s approximately finger tight. Now do the same with the 2nd hole and screw until finger tight again.
When both are finger tight, use your screwdriver to tighten them up but don’t overdo it as this can cause the reflective backing to come away around the screw hole. Use your best judgement here but normally 180 degrees past finger tight is enough.
The sticky pads supplied can be placed on the back of the plate for extra support and padding. You can also use a sticky pad or two to hold the other side of the plate in place while you tighten the first screw, ensuring it’s lined up correctly.
Front plate
Front plates are typically screwed into the bumper and don’t have fixed mounting points. Most cars have some form of plastic mounting point that can be used. The supplied screws are self-tapping and should be screwed directly into the bumper – do not pre-drill your bumper as this will prevent the screws from gripping.
For 4D number plates you must use screws – do not use the sticky pads alone as they will not provide enough strength to hold the plate on. They are for extra support and padding only. The only time sticky pads can be used alone is for regular printed plates.
Checking Your Installation for Safety and Compliance
After installing your 4D number plates, it’s important to check the installation for safety and compliance. Start by checking the alignment of the plates – they should be straight and level.
Next, check the plates are securely mounted and don’t move or vibrate. If they do, you may need to tighten up the screws.
If you’re worried about security, you can buy one-way screws online that can only be screwed down and cannot be undone. Clutch head screws are common security screws used for this purpose. Please note we do not supply these.
Finally, check your number plates are not obscured and are highly visible.
Maintaining Your 4D Number Plates After Installation
Once installed your 4D number plates are basically maintenance free. They should be washed regularly with your car with some warm soapy water to remove any build-up of dirt around the characters. This helps keep them visible and road legal.
It is safe to pressure wash your 4D digits, but don’t hold a pressure washer on for too long.
Do not use any harsh chemicals such as isopropyl alcohol as these can damage the surface of the acrylic.
Tip: add a water-repellent substance to your number plates to stop them getting covered in mud! These are available at most autocentres.
Summary
Installing 4D number plates is a simple and straightforward process that can significantly enhance the aesthetic appeal of your vehicle. By following the steps outlined in this guide, you can ensure a safe & secure installation.
Remember to prepare your vehicle properly by removing old plates and cleaning the mounting area. Gather all necessary tools, including a screwdriver, drill, and level. Follow the step-by-step guide to install the plates, ensuring they are straight, secure, and visible.
After installation, regularly check the plates for security and cleanliness. With the right care and maintenance, your 4D number plates will remain a standout feature of your vehicle for years to come.
