What modifications to the front of a vehicle would warrant a rejection?

When modifications to the front of a vehicle are assessed during an inspection, specific changes can compromise safety or performance and lead to rejection. Lowering the suspension using blocks, universal spring shackle extensions, or improper air shocks can significantly alter how the vehicle handles, affects alignment, and impacts the overall safety of the vehicle. These changes can lead to issues such as reduced clearance, which may cause the vehicle to bottom out or scrape, and could negatively influence steering and braking performance. Therefore, such modifications are often grounds for rejection during the state inspection as they do not adhere to safety and performance standards established for vehicles on the road.

In contrast, upgrades to brakes, cosmetic changes like a new paint job, or the installation of aftermarket tires don't necessarily compromise the safety or functionality of the vehicle to the same extent. Upgraded brakes, for instance, can enhance stopping power rather than diminish it, and as long as the tires meet safety requirements, changing to aftermarket options may be permissible.
