The Subaru Impreza GC8, a legendary nameplate in the rally and tuner world, has long been celebrated for its raw performance and driver-focused design. Among the many upgrades enthusiasts pursue, swapping the factory steering wheel for a Momo Monte Carlo Steering Wheel stands out as a transformative modification. This guide dives deep into why this upgrade matters, how to install it, and the tangible benefits it brings to your GC8. Whether you’re chasing lap times, enhancing daily drivability, or simply elevating your car’s aesthetics, the Momo Monte Carlo is a worthy addition.
Why Upgrade Your GC8’s Steering Wheel?
The steering wheel is your primary interface with the car—a critical component that influences control, feedback, and comfort. The GC8’s OEM steering wheel, while functional, often feels bulky and disconnected for performance driving. Here’s why an upgrade like the Momo Monte Carlo shines:
- Improved Ergonomics: A smaller diameter (typically 350mm vs. the stock 370mm) allows quicker, more precise inputs.
- Weight Reduction: High-quality materials like forged aluminum hubs and leather/suede wraps reduce rotational mass.
- Enhanced Feedback: A rigid, race-inspired design transmits road feel directly to your hands.
- Aesthetic Appeal: The Momo Monte Carlo’s vintage-meets-modern look complements the GC8’s rally-bred cockpit.
The Momo Monte Carlo: A Legacy of Performance
Momo, an Italian brand synonymous with motorsport excellence since the 1960s, designed the Monte Carlo steering wheel as a nod to its racing heritage. Key features include:
- 350mm Diameter: Ideal for balancing agility and comfort.
- Dished Design: Positions the wheel closer to the driver for a sportier seating posture.
- Premium Materials: Leather grips with contrast stitching, reinforced by a brushed aluminum core.
- Universal Compatibility: Fits most aftermarket hubs, including models for the GC8.
Installation Guide: Swapping to the Momo Monte Carlo
Tools Required:
- Socket set (19mm for steering wheel nut)
- Torx screwdriver (for airbag removal)
- Steering wheel puller
- Momo hub adapter (GC8-specific, e.g., Momo Part #2002)
- Anti-seize grease (optional)
Step 1: Disconnect the Battery
Safety first! Disconnect the negative terminal to prevent accidental airbag deployment.
Step 2: Remove the OEM Steering Wheel
- Unfasten the airbag module (usually secured by Torx screws behind the wheel).
- Disconnect the horn and airbag wiring harnesses.
- Loosen the 19mm steering shaft nut, then use a puller to detach the wheel.
Step 3: Install the Momo Hub Adapter
- Align the hub adapter with the steering column splines.
- Secure it with the provided hardware, ensuring no play exists.
Step 4: Mount the Momo Monte Carlo Wheel
- Slide the wheel onto the hub, aligning the bolt holes.
- Tighten the included Allen bolts in a star pattern to ensure even pressure.
Step 5: Reconnect Wiring and Test
- Reattach the horn wiring (if retained) and test functionality.
- Reconnect the battery and start the car to check for warning lights (airbag systems may trigger codes).
Performance Benefits: What to Expect

- Sharper Turn-In: The reduced diameter and weight make steering inputs more immediate, crucial for tight corners.
- Reduced Fatigue: The ergonomic grip minimizes hand strain during long drives or track sessions.
- Customization: Pair the wheel with a quick-release hub for easy entry/exit or additional security.
Pro Tip: Pair the Momo Monte Carlo with aftermarket bucket seats and harnesses to create a full rally-inspired setup.
FAQs: Addressing Common Concerns
1. Will this void my GC8’s warranty?
If your car is under warranty, modifying the steering wheel (and disabling the airbag) may void coverage related to the SRS system. Consult your dealer or a professional.
2. Is the Momo Monte Carlo street-legal?
Legality varies by region. Removing the airbag may violate safety regulations in some areas. Always check local laws before proceeding.
3. Does the horn still work?
Yes, but rewiring is required. Use a Momo-compatible horn button or retrofit the OEM connector.
4. Will the steering wheel fit my GC8’s column?
The Momo hub adapter (#2002) is designed for Subaru models, including the GC8. Double-check spline compatibility before purchasing.
5. How do I maintain the leather/suede finish?
Use a microfiber cloth and leather cleaner for the grips. For suede, a soft brush and specialized cleaner will preserve texture.
6. Can I retain cruise control or audio controls?
Aftermarket hubs rarely support OEM controls. Consider auxiliary switches or a secondary control panel.
7. Is professional installation recommended?
If you’re unfamiliar with airbag systems or wiring, hire a technician. Incorrect installation risks safety and functionality.
8. Does this affect resale value?
Purists may prefer stock configurations, but enthusiasts often appreciate tasteful upgrades. Keep the OEM wheel for resale.
Conclusion: Elevate Your GC8’s Potential
The Momo Monte Carlo Steering Wheel isn’t just a cosmetic tweak—it’s a performance enhancer that bridges the gap between vintage rally charm and modern precision. By improving driver input, reducing weight, and elevating aesthetics, this upgrade unlocks a more immersive driving experience in your GC8. Whether you’re threading through mountain passes or dominating autocross courses, the Momo Monte Carlo ensures you’re always in control.
