Wheel spacers are devices that go between your wheel and hub to make the distance between them bigger. Discovery 2 30 mm wheel spacers can make your vehicle look better, perform better, and handle better by giving it a wider stance and letting you fit bigger tires. However, they can also cause some possible problems, such as vibration, if they are not installed or maintained well.
One of the common questions that Discovery 2 owners have is whether 30mm wheel spacers will cause vibration. The answer is not simple, as it depends on several factors, such as the quality, type, and fitment of the spacers, as well as the state of your wheels, tires, and suspension components. But quality and fit Discovery 2 30 mm wheel spacers with proper install and torque will not cause vibration.

Quality of Discovery 2 30 mm wheel spacers
The quality of the wheel spacers is very important for avoiding vibration. You should choose high-quality spacers that are made of strong and lightweight materials, such as 6061 T6 or 7075 T6 billet aluminum. These materials are forged, not cast, which means they are more strong and less likely to crack. They also do not affect the wheel balance like steel spacers can.
You should also choose hub-centric spacers that match the center bore of your hub and wheel. Hub-centric spacers fit tightly on the hub and stop any gap or movement between the spacer and the wheel. This reduces the pressure and load on the lug nuts or bolts and stops any wobble or vibration.
You should avoid low-quality or generic spacers that are made of low-grade materials or have bad fitment or finish. These spacers can cause alignment, interference, or damage to your parts, which can lead to vibration or worse.
Type of Discovery 2 30 mm wheel spacers
The type of the wheel spacers is also important for avoiding vibration. There are two main types of spacers: slip-on and bolt-on. Slip-on spacers are simpler and cheaper to install, but they also have some limitations. They can only be used for small thicknesses (up to 5mm), and they require enough thread engagement for your lug nuts or bolts. If you use slip-on spacers that are too thick, you might not have enough thread engagement to secure your wheel properly. This can cause your wheel to come loose or fall off while driving, which can be very dangerous.
Bolt-on spacers are more secure and stable, but they also require longer lug nuts or bolts, and they might interfere with some aftermarket wheels that have recessed lug holes. Bolt-on spacers have their own studs and nuts that attach to your hub, and then your wheel attaches to the spacer’s studs and nuts. This ensures a tight and secure fitment of your wheel, but also adds some weight and complexity to your setup.
You should choose the type of spacer that fits your needs and preferences, but also matches your bolt pattern and offset. Using mismatched spacers can cause misalignment or interference issues with your parts, which can lead to vibration or worse.
Fitment of Discovery 2 30 mm wheel spacers
The fitment of the wheel spacers is also important for avoiding vibration. You should choose the right thickness and size of spacers for your vehicle, depending on your goals and preferences. The thickness of the spacers determines how much they will move your wheels outward from the center of the car.
The thicker the spacers, the more sporty and aggressive your car will look, but also the more pressure and load they will put on your parts. You should choose the thickness that gives you the appearance and performance that you want, but also keeps enough clearance and alignment for your parts.
A good way to measure the thickness you need is to use a ruler or a straight edge to measure the space between your wheel and fender, and then take away a few millimeters for safety. You should also check for any interference with your brake calipers, suspension components, or body panels.
The size of the spacers refers to their diameter and width. You should choose spacers that match the diameter of your hub bore and wheel bore, as well as the width of your wheel. This will ensure a proper fitment and balance of your wheel on the spacer.
You should also check for any changes in your offset after installing wheel spacers. Offset is the distance between the centerline of your wheel and the mounting surface of your hub. Wheel spacers reduce your offset by moving your wheels outward from the hub. This can affect your steering geometry, handling characteristics, tire wear, and gas mileage. To avoid this, you should have your alignment inspected and corrected after installing wheel spacers.

Are Discovery 2 30 mm wheel spacers safe off-road?
BONOSS Discovery 2 30 mm wheel spacers are made of high-quality material and have a good design. They are safe for your SUV and can improve your off-road and bump performance. If you use low-quality or unfit spacers off-road, you might face vibration and wobble issues and even put yourself in danger.
BONOSS spacers are made of 7075-T6 forged aluminum alloy, which is a strong and corrosion-resistant alloy that is used for aviation and marine applications. It has better mechanical properties and wear resistance than mild steel. 7075-T6 is one of the strongest commercial alloys. The wheel bolts and nuts that come with the spacers are also stable. They have ISO grade 12.9 and ISO grade 10 respectively, which means they are very hard and tough. These high-strength screws are not likely to bend or break.
BONOSS Discovery 2 30 mm wheel spacers are designed to fit different car models. For each car model, BONOSS creates suitable spacers that match the hubs and wheels. You can always find spacers with perfect fitment for your vehicles. And you can also consult with BONOSS experts to recommend fit spaces sizes and types.
Moreover, BONOSS Discovery 2 30 mm wheel spacers are multi-stage and hub-centric, which means they can fit securely between the hubs and wheels. To fit tightly, BONOSS spaces have stages and chamfers on the lips that match the shape of the hub bore and wheel bore.
When you install BONOSS Discovery 2 spacers on the hubs, they are tight and hard to remove. Don’t worry! On the side of the spacers, there are grooves for dismounting. You can easily remove spacers with a screwdriver. Even when they are stuck after a long time, these grooves can help you dismount spacers easily.
