- High performance tires: Made to increase grip on the road, high performance tires can deform on a sharp turn, contributing to the likelihood of a rollover accident because of contact between a tire rim and the pavement. Inappropriate marketing or installation of tires on a sports utility vehicle (SUV) can contribute to rollover accidents giving rise to liability on the part of a manufacturer, distributor, or retailer.
- Spoilers: Used to increase downward force on a vehicle, spoilers can contribute to devastating rollover accidents. By altering handling and performance, aftermarket spoilers can be dangerous to drivers or their passengers unaware of their affect on a car traveling at high speeds.
- Vehicle alterations: Raising or lowering the suspension of a vehicle can have a significant affect on the likelihood of a vehicle rollover in an emergency situation.
- Vehicle additions: The addition of window tinting, extra-powerful headlights, tinted headlights, or fog lights can be dangerous additions to vehicles, both as hazards for the driver and oncoming traffic in inclement or nighttime driving conditions. These kinds of additions can be found at the Automotive Aftermarket Industry Association.
While aftermarket alterations to a vehicle are commonly done by end-users, oftentimes alterations are made to the body—and thus the performance—of a vehicle after it has been manufactured but prior to its delivery by the end-use purchaser.
Types of aftermarket vehicles include:
