Cold Air Intake

A key modification for your Mustang, this allows cold, dense air into your engine quickly. More horsepower is freed up as a result.

On top of this, a modified exhaust system can make your Mustang really roar, letting everyone know it’s not just a run-of-the-mill car.


A supercharger is an effective way to provide an immediate boost in power to every part of your powerband. Depending on the application a supercharger can add up to 100 HP making it one of the most powerful modifications you can get.

These can be used with automatic or manual transmissions, and transmission wear isn’t increased when shifting gears with a supercharger under normal driving conditions.


Independent rear suspension can help improve the handling of your car. Cornering becomes better and brake drive is reduced. This also serves as a potential aesthetic improvement.

Front Bumper and Chin Spoiler

Rear Spoiler

Adding a new front bumper and chin spoiler gives a fierce look upfront, and this should be completed at the rear with a new spoiler.

Window Louvres

To really get that classic look another modification you can add to your Mustang is quarter and rear window louvers. These can certainly turn your car into a head-turner while adding an element of style to an already iconic car.
