Before you conduct any car alterations, read the guide to illegal car modifications for all states. Vehicles undergo performance and appearance alterations depending on their tastes and preferences. Some of the reasons that lead to car modification decisions include improved engine performance, better handling and driving, and efficient fuel consumption. In addition, you may want to modify your vehicle to suit your lifestyle, tastes, and preferences. However, it's essential to consider that car alterations may be costly and cause a safety concern. Some car modifications, such as an engine change, could have your warranty voided and lead to increased insurance claims. Vehicle alterations may also affect your vehicle's resale value. Below are some car modifications you should consider.

1. Install spoilers

The type and positioning of a spoiler can affect a car’s performance, and while most of them are found in the rear of a vehicle, others can be positioned in front. They improve airflow over and above a car, resulting in better road grip. This makes fast-moving vehicles easy to control without any extra weight. Adding spoilers to your vehicle also improves its braking stability by raising the downward force on the car's back. Consider using lightweight materials for a trunk spoiler, such as carbon, fiberglass, and silicon to give your vehicle an OEM+ appearance.

2. Engine ECU tuning

Most recent engines are operated by engine control units (ECU) which determine the amount of fuel injected into the engine cylinders and the ignition timing. Usually, ECUs are optimized for drivability, better fuel efficiency, durability, and performance from the factory. However, the driver may go to the aftermarket to have these and other parameters changed depending on their needs.

3. Consider installing performance tires

Low-quality tires are a vehicle's biggest downside. Getting custom-made performance tires improves your car’s handling, giving you a tighter steering, high road presence, and an appearance upgrade. For your daily commute, avoid using soft tires due to poor gas mileage and faster tread wear. Consider choosing good-quality tires that suit your needs and style. A tire's upgrade cost depends on the brand, size, and design. Additionally, a tires upgrade also requires a set of high-end lightweight rims to boost your car's performance, safety, and aesthetics. 

4. Upgrade the brakes

A vehicle's safety highly depends on its braking system, and with a good car brake, a car should stop when you need it to. Upgrading your car’s braking system allows you a shorter braking distance, improving your car's performance.

5. Don’t forget your cars height

Lowering your car's height reduces its center of gravity, improving your car’s handling and stability. When you drop your vehicle, it becomes stiffer, benefitting your car's stability at the expense of some of your comfort. For off-roading vehicles, consider increasing the height to increase ground clearance.

6. Upgrade your seat covers

High-quality seat covers protect your seats against water, mud, oil, and damage from UV rays. Besides giving your seats a sleek look and longevity, quality seat covers come with cushion backing, storage pockets, and airbag tearaways.


Car modifications are a great way to customize and add a sense of personal touch to suit your lifestyle. It also boosts your vehicle's performance and appearance. Consider using these tips for your car alterations.
