Wheel Fitment Guidelines for Lowering Your Subaru Brz Without Tire Rubbing

Lowering your Subaru BRZ can significantly improve its appearance and handling. However, it also introduces the challenge of ensuring proper wheel fitment without causing tire rubbing or suspension issues. Understanding the key guidelines for wheel fitment is essential for a safe and stylish upgrade.

Understanding Wheel Fitment Basics

Wheel fitment refers to how well your wheels and tires fit within the wheel arches and suspension components. Proper fitment ensures optimal handling, prevents tire rubbing, and maintains suspension integrity. When lowering your BRZ, you need to consider several factors, including wheel size, offset, and tire dimensions.

Key Factors for Lowered Subaru BRZ

  • Wheel Diameter and Width: Opt for wheels that are slightly smaller or equal to stock diameter but with a wider width for better grip and stance.
  • Offset (ET): A lower offset pushes the wheel outward, filling the wheel arch better but risking rubbing if too low.
  • Tire Size: Choose tires with appropriate sidewall height to prevent contact with suspension components.
  • Suspension Travel: Lowering reduces suspension travel, so maintain a balance to avoid bottoming out or rubbing.

For a lowered Subaru BRZ, consider the following specifications:

  • Wheel size: 17″ or 18″ diameter
  • Wheel width: 7.5″ to 8.5″
  • Offset: +35 to +45 mm
  • Tire size: 215/40 or 225/40 for 17″ wheels; 215/40 or 225/40 for 18″ wheels

Tips to Avoid Tire Rubbing

To prevent tire rubbing when lowering your BRZ, follow these tips:

  • Choose wheels with appropriate offset to avoid too much outward push.
  • Use tires with a sidewall height that complements your lowered suspension.
  • Install fender rollers if necessary to create additional clearance.
  • Consider a slight camber adjustment to improve fitment and stance.

Conclusion

Lowering your Subaru BRZ enhances its style and performance, but proper wheel fitment is crucial to avoid tire rubbing and suspension issues. By selecting the right wheel size, offset, and tire dimensions, you can achieve a lowered stance that looks great and drives smoothly. Always consult with a professional for custom setups and installation to ensure safety and optimal results.
