The join between these two sections can only have one curve, and any rounded edges at this junction can't exceed 50mm in radius.
- Upper and floor bodywork must be neatly joined together with proper alignment
- Engine cover cannot extend below the floor bodywork level
- The intersection between upper and floor bodywork must create only one curve (not multiple curves)
- Fillet radius (rounded edges) at the junction cannot exceed 50mm
