• Precise fit to the trunk well – no need for modifications or custom spacers.
• Compatibility with the factory spare wheel mounting system – easy installation and removal in workshop or home conditions.
• Consistency with the original body structure – maintaining the mounting method intended by the manufacturer.

Such a solution is beneficial both for daily use and when reselling the car, where maintaining original mounting components is often an additional asset.
