The lowered ride height gives the car a more aggressive and sporty stance, making it stand out from the crowd. The reduced gap between the tires and the fender wells creates a cleaner and more streamlined look, which many enthusiasts find aesthetically pleasing. However, it's important to note that lowering the ride height can also have some drawbacks. It can reduce ground clearance, making the car more susceptible to scraping on speed bumps and steep driveways. It can also affect the alignment of the suspension, requiring adjustments to ensure proper handling and tire wear. Therefore, it's essential to carefully consider the pros and cons before installing AMP springs, and to choose a ride height that is appropriate for your driving conditions and personal preferences. A professional installation and alignment are highly recommended to ensure optimal performance and safety.

When selecting AMP springs for your GTI MK7, it's crucial to choose a spring rate that is appropriate for your driving style and the type of roads you typically drive on. A stiffer spring rate will provide better handling, but it may also result in a harsher ride. A softer spring rate will be more comfortable, but it may not provide as much of an improvement in handling. It's also important to consider the amount of lowering that the springs provide. A lower ride height will improve handling and appearance, but it may also reduce ground clearance and increase the risk of scraping. It's a good idea to research different spring options and read reviews from other GTI owners to get a sense of what works best for different applications. You may also want to consult with a suspension specialist who can provide personalized recommendations based on your specific needs and preferences. Ultimately, the goal is to find a set of AMP springs that will enhance the performance and appearance of your GTI MK7 without compromising comfort or practicality.
