Securing a spare wheel in a rally car is crucial for safety and performance during a race. Properly fastening the spare ensures it doesn’t become a hazard during high-speed maneuvers or rough terrain. Here’s a step-by-step guide on how to do it effectively.
Why Secure a Spare Wheel in a Rally Car?
In rally racing, drivers encounter various terrains that can lead to tire damage. Having a secure spare wheel ensures you’re prepared for quick tire changes without compromising safety or speed. A loose wheel can shift weight distribution, affect handling, or become a dangerous projectile in an accident.
Steps to Secure a Spare Wheel
-
Choose the Right Location: The spare wheel should be placed in a location that maintains the car’s balance. Typically, it’s mounted in the trunk or rear compartment, close to the car’s centerline.
-
Use a Proper Mounting System: Invest in a high-quality mounting bracket or strap system designed for rally cars. These systems are engineered to withstand the rigors of racing.
-
Ensure Tight Fit: The spare wheel should fit snugly within its mount. Use adjustable straps or a ratchet system to eliminate any movement.
-
Check Weight Distribution: Once the wheel is secured, ensure it doesn’t affect the car’s balance. Adjust other cargo or ballast as necessary to maintain optimal weight distribution.
-
Regular Inspection: Before each race, inspect the mounting system for wear and tear. Replace any damaged components to ensure reliability.
Tools and Equipment for Securing a Spare Wheel
- Mounting Bracket: Provides a stable base for the wheel.
- Ratchet Straps: Offers adjustable tension to keep the wheel in place.
- Torque Wrench: Ensures all bolts and fasteners are tightened to the correct specifications.
- Anti-Slip Mat: Placed under the wheel to prevent movement.
Practical Example: Securing a Spare Wheel
Consider a rally team using a Subaru WRX STI. They opt for a custom-built aluminum bracket bolted to the trunk floor. The spare wheel is secured with heavy-duty ratchet straps, ensuring no movement during aggressive driving. By placing the wheel close to the car’s centerline, they maintain optimal handling and performance.
