Do you need to modify the interior of your rally car to fit a roll cage? Yes, installing a roll cage in your rally car often requires modifications to the interior to ensure proper fitment and safety. These changes can include removing or altering seats, carpets, and other interior components to accommodate the cage’s structure and ensure compliance with racing regulations.

What is a Roll Cage and Why is it Important?

A roll cage is a specially designed frame built inside a vehicle to protect the driver and passengers in the event of a rollover or crash. It is a critical safety feature in rally cars, as it provides structural support and minimizes the risk of injury during high-speed racing. Roll cages are typically made from steel or aluminum and are custom-fitted to each vehicle for maximum effectiveness.
