2. Cost: The price tag for the ChassisWorks kit is higher than some alternatives, which may be a deterrent for some buyers.

3. Customization limitations: Since the kit is a one-size-fits-all solution, it may not provide the same level of customization as a custom-fabricated frame.

4. Potential alignment issues: Lowering the ride height may lead to alignment issues if not addressed properly during installation or if the suspension setup is not compatible.
