The Dodge Hellcat, with its impressive 750 horsepower, is a beast on the road. However, when it comes to wheel fitment, many owners encounter rub issues that can affect performance and handling. In this article, we will explore common wheel fitment problems and provide solutions to fix these issues.
Understanding Wheel Fitment
Wheel fitment refers to how well a wheel matches the specifications of a vehicle. For the Dodge Hellcat, proper fitment is crucial for optimal performance. Incorrect fitment can lead to rubbing against the fender, suspension components, and other parts of the vehicle.
Common Rub Issues
- Inadequate wheel offset
- Incorrect tire size
- Lowered suspension
- Wheel arch clearance
- Aftermarket modifications
Inadequate Wheel Offset
Wheel offset is the distance between the wheel’s centerline and the mounting surface. An inadequate offset can cause the wheel to sit too far in or out, leading to potential rubbing. If the wheel sticks out too much, it can rub against the fender or bodywork.
Incorrect Tire Size
Using tires that are too wide or too tall can lead to rubbing against the wheel wells. It’s essential to choose the right tire size that matches the Hellcat’s specifications. Always consult the manufacturer’s recommendations for optimal tire dimensions.
Lowered Suspension
Lowering the suspension can enhance handling but may also reduce wheel clearance. If the vehicle is lowered too much, it can cause the tires to rub against the fenders during turns or when hitting bumps. Adjustments may be necessary to maintain proper clearance.
Wheel Arch Clearance
Wheel arch clearance is the space between the tire and the fender. If this space is insufficient, it can lead to rubbing. Owners should check the clearance when the vehicle is loaded and during full suspension travel to ensure no contact occurs.
Aftermarket Modifications
Aftermarket modifications, such as wider wheels or body kits, can significantly impact fitment. These changes may require adjustments to the suspension or wheel alignment to prevent rubbing. Always consider the implications of modifications on overall fitment.
Solutions to Fix Rub Issues
- Adjust wheel offset
- Select appropriate tire sizes
- Modify suspension height
- Use wheel spacers
- Reinforce wheel arch clearance
Adjust Wheel Offset
Changing the wheel offset can help achieve a better fit. If the wheels are too far out, consider using wheels with a higher offset. Conversely, if they are too far in, a lower offset will create more space.
Select Appropriate Tire Sizes
Choosing the right tire size is crucial for preventing rub issues. Consult the vehicle’s specifications and choose tires that fit within the recommended limits. It’s often beneficial to compare the overall diameter and width with stock options.
Modify Suspension Height
If the suspension is lowered, consider raising it slightly to improve clearance. Adjusting the suspension height can alleviate rubbing issues while maintaining performance benefits. Consult a professional for precise adjustments.
Use Wheel Spacers
Wheel spacers can help push the wheels away from the suspension and body, increasing clearance. However, ensure that the use of spacers does not adversely affect the vehicle’s handling or safety.
Reinforce Wheel Arch Clearance
For vehicles experiencing rubbing against the fenders, modifying the wheel arches can provide additional clearance. This could involve rolling the fenders or trimming excess material carefully to prevent contact.
Conclusion
Fixing rub issues on a 750 hp Dodge Hellcat requires understanding wheel fitment and addressing common problems. By making the necessary adjustments to wheel offset, tire sizes, and suspension height, owners can enjoy a smooth and performance-oriented driving experience. Always consult with professionals when making significant modifications to ensure safety and effectiveness.
