### **Pros and Cons of buying a Toyota SU003-05128 (2017-2020 86 ZN6 Trunk Deck Lid Weather Strip Seal Rubber for FR-S/BRZ)**
#### **Pros:**1. **OEM Quality and Fit** This part is designed as an original equipment manufacturer (OEM) replacement, meaning it should fit perfectly without modifications. It is engineered to match the specifications of the factory seal, ensuring proper function and longevity.
2. **Durability and Weather Resistance** The rubber material is formulated to withstand exposure to UV rays, moisture, and temperature fluctuations, which helps prevent cracking, swelling, or degradation over time. This is crucial for maintaining a watertight seal in the trunk lid.
3. **Prevents Water Leaks and Rust** A properly sealed trunk lid prevents water from seeping into the vehicle s cargo area or lower body panels. This reduces the risk of rust formation, especially in regions with harsh weather conditions or frequent rain.
4. **Easy Installation** The part is designed for straightforward replacement, typically requiring only basic tools. Many users report that it can be installed in under an hour with minimal effort, provided they follow the correct procedure.
5. **Compatibility with Multiple Models** While primarily intended for the **Toyota 86 (ZN6)** and **Scion FR-S**, this part may also fit other models in the same platform (e.g., some Lexus GS or Toyota GR86 variants), depending on the exact year and trim. Always verify compatibility before purchasing.
6. **Cost-Effective Long-Term Solution** Replacing a worn-out weather strip is far cheaper than dealing with potential structural damage (e.g., rust, electrical issues, or interior water damage) caused by a failing seal.
7. **Improves Resale Value** A well-maintained vehicle with no visible leaks or rust issues holds its value better. Replacing the weather strip as part of routine maintenance can contribute to a cleaner resale record.

#### **Cons:**1. **Limited Availability and Lead Times** OEM parts, especially for niche models like the FR-S or 86, may not be readily available at all auto parts stores. Purchasing online (e.g., from Toyota dealerships, eBay, or specialty suppliers) may result in longer shipping times or higher costs.
2. **Potential Counterfeit or Low-Quality Alternatives** If buying from third-party sellers, there is a risk of receiving a **non-OEM replica** that may not fit correctly, degrade quickly, or fail to provide a proper seal. Always check seller ratings and verify the part s authenticity.
3. **Installation Challenges for DIYers** While the part itself is relatively simple to install, some users may struggle with removing the old seal (especially if it s stuck due to age or adhesive). Improper removal can damage the trunk lid or surrounding panels.
4. **Price Premium Over Aftermarket Options** OEM parts are typically more expensive than aftermarket alternatives. While aftermarket seals may be cheaper, they might not offer the same durability or fit as precisely as an OEM part.
5. **Wear and Tear Over Time** Even with proper installation, rubber seals degrade over time due to exposure to the elements. The part may need replacement again in **3 5 years**, depending on driving conditions and maintenance.
6. **Misalignment or Improper Sealing** If not installed correctly (e.g., uneven pressure, gaps, or misalignment), the new seal may not function as intended, leading to leaks or premature failure.

### **Conclusion**
The **Toyota SU003-05128 (2017-2020 86 ZN6 Trunk Deck Lid Weather Strip Seal)** is a **high-quality, OEM-replacement part** that offers significant long-term benefits for preventing water ingress, rust, and structural damage.
