But before you start chucking spacers on, there’s a lot to consider.
The right size is key, and getting it wrong can lead to all sorts of issues. We’re talking potential damage to your suspension, uneven tyre wear, and even the risk of your wheels coming loose while you’re driving. Not exactly the kind of thing you want to deal with, right? So, how do you figure out the right size, and what are the other things you need to know?
Let’s dive in.
Understanding Wheel Spacers
Wheel spacers are metal or plastic rings that are installed between the wheel hub and the wheel, effectively increasing the distance between the wheel and the vehicle’s body. This modification, often used in the automotive aftermarket, plays a crucial role in altering the vehicle’s stance and wheel offset.
Types of Wheel Spacers
Wheel spacers come in various materials and construction methods, each with its own characteristics and suitability for different applications.
- Aluminum Spacers: Lightweight and commonly used, offering a good balance of strength and affordability. These spacers are typically CNC-machined for precise fitment and durability.
- Steel Spacers: Stronger and more durable than aluminum spacers, making them suitable for heavier vehicles or those subjected to high loads. However, they are heavier and can add unwanted weight to the suspension.
- Plastic Spacers: Less common than metal spacers, these are often used for smaller increases in wheel offset. While they are lightweight and affordable, they may not be as durable as metal spacers, especially under high stress.
Advantages and Disadvantages of Wheel Spacers
Wheel spacers can offer several advantages, but it’s essential to understand their potential drawbacks before making a decision.
- Advantages:
- Improved Stance: Wheel spacers can widen the vehicle’s stance, giving it a more aggressive and visually appealing look. This can also improve the vehicle’s handling characteristics, particularly in cornering.
- Increased Wheel Offset: By moving the wheels further outward, spacers can increase the wheel offset, providing more clearance for larger wheels or tires.
- Enhanced Wheel Clearance: Wheel spacers can help avoid tire rubbing against the vehicle’s body, especially when installing larger wheels or tires.
- Disadvantages:
- Reduced Wheel Bearing Life: Installing wheel spacers can put additional stress on the wheel bearings, potentially reducing their lifespan. The added stress can also lead to premature wear and tear on other suspension components.
- Increased Risk of Wheel Vibration: Improperly installed or low-quality spacers can introduce vibrations into the steering wheel, especially at higher speeds.
- Potential for Damage: In extreme cases, wheel spacers can cause damage to the vehicle’s brake lines, suspension components, or even the wheel hub itself.
- Negative Impact on Handling: While wheel spacers can improve handling in some situations, they can also negatively affect the vehicle’s handling, particularly in terms of stability and responsiveness. This is because they can alter the vehicle’s suspension geometry, leading to unpredictable behavior.
- Increased Tire Wear: The change in wheel offset caused by spacers can affect the tire’s wear pattern, potentially leading to uneven wear and reduced tire life.
Determining the Right Size
Choosing the correct wheel spacer size is crucial for a safe and proper fit. Several factors play a role in determining the appropriate spacer thickness. This includes understanding your vehicle’s specifications, existing wheel offset, and tire size.
Vehicle Specifications
The first step in determining the right spacer size is to identify your vehicle’s make, model, and year. This information is essential because different vehicles have different wheel bolt patterns, hub bore sizes, and suspension setups. These specifications dictate the type and size of wheel spacers that are compatible with your vehicle.
Measuring Existing Wheel Offset, What size wheel spacers do i need
The wheel offset, also known as the ET value, refers to the distance between the mounting surface of the wheel and the center of the wheel. To measure the existing wheel offset, you can use a measuring tape or calipers. Place the measuring tool against the mounting surface of the wheel and measure the distance to the center of the wheel.
Calculating Spacer Thickness
Once you have measured the existing wheel offset, you can calculate the necessary spacer thickness. The formula for calculating spacer thickness is:
Spacer Thickness = Desired Offset – Existing Offset
For example, if you want to increase the offset by 10mm and your existing offset is 45mm, the required spacer thickness would be 10mm.
Considering Tire Size and Wheel Width
The size of your tires and the width of your wheels also play a role in determining the appropriate spacer size. If you are using larger tires or wider wheels, you may need thicker spacers to ensure proper clearance and prevent rubbing.
It is important to note that using spacers can affect the handling and stability of your vehicle. Using excessively thick spacers can lead to issues such as increased stress on wheel bearings, suspension components, and steering components.
Compatibility and Installation: What Size Wheel Spacers Do I Need
Before you dive into installing wheel spacers, it’s crucial to make sure they’re compatible with your vehicle. This involves verifying several factors, including the wheel studs, hub bore, and brake caliper clearance.
Compatibility Check
It’s crucial to confirm compatibility to ensure a safe and smooth installation process.
- Wheel Stud Length: Wheel spacers increase the distance between the wheel and the hub. Therefore, you need to ensure that the wheel studs are long enough to accommodate the spacer and still securely fasten the wheel. If the studs are too short, the wheel might not be securely attached, leading to potential safety hazards.
- Hub Bore: The hub bore is the central hole in the wheel that fits over the hub of the vehicle. Wheel spacers should have a hub bore that matches the hub bore of your vehicle. A mismatch can result in an unstable wheel, potentially leading to vibrations and even wheel separation.
- Brake Caliper Clearance: Ensure that there is enough clearance between the wheel spacer and the brake caliper. If the spacer is too thick, it can interfere with the caliper, leading to braking issues or even damage to the caliper.
Installation Procedure
Once you’ve confirmed compatibility, you can begin the installation process. Here’s a step-by-step guide, ensuring safety is paramount:
- Preparation: Park your vehicle on a level surface and engage the parking brake. Use a jack to lift the vehicle and secure it with jack stands. Remove the wheel that you want to install the spacer on.
- Install the Spacer: Place the spacer on the hub, ensuring it’s properly aligned with the hub bore. Align the spacer with the studs.
- Install the Wheel: Place the wheel onto the spacer and align the wheel studs with the wheel’s lug holes.
- Tighten the Lug Nuts: Start by hand-tightening the lug nuts.
- Torque the Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications. The torque setting will be listed in your vehicle’s owner’s manual.
- Check for Tightness: After driving a short distance, re-check the lug nuts for tightness.
Torque Settings and Thread Locker
Using the correct torque settings is crucial for ensuring the safe and secure installation of wheel spacers.
- Torque Settings: The torque settings for lug nuts vary depending on the vehicle and wheel size. Always refer to your vehicle’s owner’s manual for the recommended torque settings.
- Thread Locker: Applying thread locker to the lug nut threads helps to prevent them from loosening over time. Thread locker is particularly important for wheel spacers, as they are subjected to greater stress than the original wheel studs.
Considerations and Risks
While wheel spacers can enhance the look and handling of your vehicle, it’s crucial to be aware of the potential risks associated with their use. Installing spacers without proper consideration and understanding can lead to complications and compromise your vehicle’s safety.Wheel spacers can alter the geometry of your suspension, putting additional stress on components like wheel bearings, axles, and suspension arms.
This increased stress can accelerate wear and tear, leading to premature failure of these parts. Additionally, spacers can increase the risk of wheel separation, particularly at high speeds or during aggressive driving maneuvers. This can be a serious safety hazard, potentially causing accidents.
