2. **Installation Complexity** These brakes often require professional installation due to their precision engineering and potential need for alignment or calibration after fitting. DIY installation may be challenging for those without mechanical experience.
3. **Potential for Overkill** If your driving is mostly light or suburban, these brakes may offer little practical benefit beyond stock options. The performance gains might not justify the cost for everyday use.
4. **Maintenance Requirements** High-performance brakes require more frequent inspections, pad replacements, and fluid flushes to maintain optimal function. Neglecting maintenance can lead to reduced lifespan or failure.
5. **Noise Sensitivity** Some drivers report that S&S brakes can be slightly noisier than stock or softer aftermarket options, particularly under hard braking or when new. This may not be an issue for all, but it s worth considering if noise is a concern.
6. **Limited Stock Availability** As a specialized performance part, these brakes may not be as widely stocked as more common brake kits, potentially requiring special ordering or longer wait times.
