Expert Advice: Consider your primary driving purpose when selecting rims. For track use, prioritize lightweight forged options; for show cars, appearance and finish quality might take precedence; for daily drivers, seek a balance of durability, maintenance requirements, and style.
DIY Installation Guide
Installing Mustang 20-inch rims yourself can save money and provide a satisfying project experience. Follow this comprehensive step-by-step process for a successful installation:
Required Tools and Materials
| Essential Tools | Optional Tools | Materials |
|---|---|---|
| Lug wrench or socket set | Impact wrench | New 20-inch rims and tires |
| Torque wrench | Rubber mallet | Anti-seize compound |
| Jack and jack stands | Valve stem core tool | Wheel weights (if balancing yourself) |
| Wheel chocks | Pressure gauge | Tire pressure monitor sensors (if needed) |
Installation Process
-
Preparation
Park your Mustang on a level, solid surface. Apply the parking brake and place wheel chocks on the opposite end of the car from where you'll start working. Loosen (but don't remove) the lug nuts on the first wheel while it's still on the ground.
-
Elevate the Vehicle
Use the jack at the manufacturer's recommended lifting point to raise the car. Once elevated, secure the vehicle with jack stands placed at appropriate support points. Never rely solely on a jack to support the vehicle's weight during wheel changes.
-
Remove the Original Wheels
Fully remove the lug nuts, keeping them organized. Carefully pull the wheel straight off the hub, using a gentle rocking motion if necessary. Be mindful of the brake components while removing the wheel.
-
Prepare the New Rims
If transferring tire pressure monitoring sensors (TPMS) from old wheels, do so now. Ensure the new rims have tires properly mounted and balanced. Check that the center bore matches your Mustang's hub diameter.
-
Install the New Rims
Apply a small amount of anti-seize compound to the hub center (not the lug studs). Carefully align the new wheel with the lug studs and hub, then push it fully onto the hub. Hand-thread the lug nuts in a star pattern.
-
Secure and Torque
Lower the vehicle so the tire contacts the ground but doesn't bear full weight. Tighten the lug nuts in a star pattern to the manufacturer's specified torque (typically 100-110 ft-lbs for Mustangs) using a torque wrench. Never use an impact wrench for final tightening.
-
Final Steps
Fully lower the vehicle, remove jack stands, and verify proper tire pressure in all new tires. Take a short test drive at moderate speeds, then re-check lug nut torque after 50-100 miles as they may settle.
Safety Warning: Always use proper jack stands when working under a vehicle. Never rely on a hydraulic jack alone to support the weight of your Mustang during wheel installation.
Frequently Asked Questions
No, not all Mustang models can accommodate 20-inch rims. While many modern Mustangs (particularly 2005+ models) are designed to accept 20-inch wheels, some older generations or base trim levels may require modifications to fit this size. The compatibility depends on several factors:
- Model year and generation (S197, S550 platforms have better compatibility)
- Suspension type and ride height
- Brake caliper size and clearance requirements
- Wheel well dimensions
Always consult your owner's manual, a Ford dealership, or a wheel fitment guide specific to your Mustang's year and trim level before purchasing 20-inch rims.
20-inch rims offer several significant advantages over smaller wheel options for Mustang owners:
Performance Benefits
- Enhanced cornering stability due to reduced sidewall flex
- Improved handling responsiveness and driver feedback
- Potential for larger brake components
- Better dry-road traction with wider contact patch
Aesthetic Advantages
- More aggressive, modern appearance
- Reduced visual gap between tire and wheel well
- Enhanced prominence of brake components
- Greater customization options with various designs
The primary tradeoff is a potentially firmer ride quality due to the reduced tire sidewall height, which provides less cushioning against road imperfections.
