Going overboard with accessories can make your car look better but can destroy other aspects.
1. Huge rims
While big rims can definitely look good, a lot of times people go overboard with their choice of wheel sizes. Making a shift from stock 15-inch wheels to slightly larger and sportier 16-inch ones wouldn’t be much of a problem, but when you start going more than 2 or 3-inches over the manufacturer’s tyre size, you can soon run into trouble. If your overall wheel diameter, that is rim and tyre exceeds what the manufacturer has made, the tyres can start rubbing against the wheel well liner each time you go through a bump.
2. Ultra low profile tyres
Low profile tyres have very rigid side walls and hence offer very little flexibility. While this might be desirable on the race track, where you want your car’s tyres to flex as little as possible under immense cornering forces, it does make for a very hard ride. A less flexible tyre will transmit more forces to the car’s suspension, adding significantly more wear and tear to the various suspension components.
Spoilers are mounted on the back of racing cars to create downforce at high speeds, which pushes the back down and provides cornering grip. Most aftermarket spoilers one gets at car accessory shops are merely show bits, and don’t really create any downforce. In fact, road cars are perfectly capable of cornering at the limits they’ve been designed with without the need for spoilers. All an aftermarket spoiler will do is result in lower fuel economy.
4. Body kits
The job of wide-body kits and air dams is to channel air over and under the car to achieve the optimal drag coefficient, as well as channeling extra air to the radiator, brakes and intake system. All this is fine when your car is a high performance fire-breather. But to slap on a body kit on your humble sedan or hatchback is overkill, and more often than not is going to interfere with movement of the wheels, either in the suspension travel department or steering angle department.
5. Colored or masked headlights
Masking a part of your headlights to get that eyelid effect is illegal to modify and is also dangerous as it affects the illumination and pattern of your lights on the road. The standard transparent bulb with the yellowish light is the best option.
