This high-quality spacer is crafted to bridge the gap between the gas tank and the spare tire cover, ensuring a seamless, factory-like appearance that enhances the car s timeless elegance. Engineered from durable, corrosion-resistant materials, it is built to withstand the rigors of daily driving, extreme weather conditions, and the occasional off-road excursion that the 930 s performance-oriented nature demands. The spacer features precise, custom-fit dimensions tailored specifically for the 997.2 generation of the 911, accommodating the larger gas tank and spare tire assembly found in this model variant. Beyond its visual appeal, this component also serves a practical purpose by maintaining proper alignment and clearance, preventing potential interference with the spare tire cover or surrounding bodywork during operation. Whether installed on a classic race-prepped 930 or a meticulously restored show car, this spacer is an essential upgrade for enthusiasts seeking to preserve the 911 s signature rear profile while ensuring long-term reliability. Its installation is straightforward, requiring minimal modification to existing components, and it seamlessly integrates with the existing gas tank and spare tire assembly, offering a perfect blend of form and function. For owners of the 911 930 who prioritize both performance and precision, this spacer is an indispensable addition to maintain the car s heritage while adapting to modern demands.

### **Pros and Cons of Buying a Porsche 911 (997.2) Gas Tank Spare Tire Spacer (Part Number: 20129101)**

1. **Improved Aesthetics** The spacer replaces the stock spare tire cover, giving the car a cleaner, more streamlined look by eliminating the bulky spare tire well. This is particularly appealing for those who prioritize a sleek, modern appearance.

2. **Weight Reduction** Removing the spare tire and its well reduces the overall weight of the vehicle, which can slightly improve handling and fuel efficiency, though the impact is minimal in a high-performance car like the 911.

3. **Increased Cargo Space** The trunk area becomes more usable since the spare tire no longer occupies space. This can be beneficial for those who occasionally carry luggage or other bulky items.

4. **Compatibility with Aftermarket Mods** Some owners opt for aftermarket exhaust systems or underbody modifications that may conflict with the stock spare tire well. A spacer allows for easier installation of these modifications.

5. **Maintenance Convenience** If you rarely use the spare tire (or never do), removing it eliminates the need to check its pressure and condition regularly.

6. **Enhanced Underbody Clearance** The spacer raises the gas tank slightly, which can help prevent minor scrapes or damage when driving over rough terrain or parking in tight spaces.

7. **Resale Value Retention** Since the modification is relatively common and reversible, it may not negatively impact the car s resale value if done professionally and documented.

1. **Loss of Spare Tire** The most significant drawback is the absence of a spare tire. While the 911 s fuel efficiency and high-performance tires make a flat tire less likely, it s still a risk. Without a spare, you re dependent on roadside assistance or towing, which can be inconvenient in remote areas.

2. **Potential Fuel Tank Exposure** The gas tank is now more exposed to road debris, rocks, or minor impacts, which could lead to punctures or leaks over time. While the tank itself is robust, the risk is slightly higher than with the protective well.

3. **Increased Risk of Fuel Leaks** If the tank or fuel lines are damaged (e.g., from a collision or road debris), the lack of a spare tire well means there s no secondary barrier to contain leaks before they reach the ground.

4. **Voided Warranty (If Applicable)** Some Porsche dealerships or insurance providers may consider this modification a violation of warranty terms, especially if it involves altering factory components. Always check with your insurer before proceeding.

5. **Potential Drivetrain or Suspension Interference** In rare cases, improper installation or aftermarket modifications (e.g., lowered suspension) could cause the spacer to interfere with the driveshaft, exhaust, or other components. This risk is low but not nonexistent.

6. **Reduced Resale Appeal for Some Buyers** While not a dealbreaker for most enthusiasts, some potential buyers (particularly those who prioritize practicality over aesthetics) may view the lack of a spare tire as a negative.

7. **Installation Complexity** Removing the spare tire well and gas tank requires careful disassembly of the rear subframe and fuel system. If not done correctly, it could lead to leaks, misalignment, or other issues. Professional installation is highly recommended.

8. **Potential for Rust or Corrosion** The area where the spare tire well was mounted may become exposed to moisture, increasing the risk of rust over time, especially in humid or salty climates.

The Porsche 911 gas tank spare tire spacer is a popular modification for those who prioritize aesthetics and weight reduction over practicality. It offers a significant visual upgrade and minor performance benefits, but it eliminates the spare tire a critical safety feature. The decision to install one depends on your priorities:

- **Install it if:** You rarely drive in remote areas, have reliable roadside assistance coverage, and are comfortable accepting the trade-off of no spare tire. You also value the improved look and potential weight savings.

- **Avoid it if:** You frequently travel off-road, live in an area with poor roadside assistance, or prioritize safety and practicality over aesthetics. Additionally, if you plan to keep the car long-term, the lack of a spare tire could become a liability.

For most enthusiasts, the spacer is a worthwhile modification **as long as you re prepared for the consequences of not having a spare tire**. If you decide to proceed, ensure the installation is done by a qualified Porsche specialist to avoid complications.

1. **Research thoroughly** Understand the risks and ensure you have a backup plan (e.g., a portable tire inflator, roadside assistance membership, or a spare tire stored elsewhere).

2. **Get a professional installation** Attempting DIY installation on a Porsche s fuel system is risky. A dealer or experienced mechanic should handle it.

3. **Document the modification** Keep records in case of warranty or insurance issues.

4. **Consider alternatives** If you re concerned about safety, explore other aesthetic upgrades (e.g., custom wheel covers, exhaust modifications) that don t eliminate the spare tire.

Ultimately, the spacer is a cosmetic and weight-saving modification rather than a performance-enhancing one. Weigh the pros and cons carefully before deciding.
