Eibach Pro-Kit for 2015 Subaru WRX STI 2.5L Turbo

The Eibach Pro-Kit uses a spring rate that is approximately 10% stiffer than stock, which helps reduce body roll during cornering. This well-built set of lowering springs is designed specifically for the 2015-2021 Subaru WRX STI, offering a noticeable improvement in both performance and appearance. By lowering the vehicle's center of gravity, these springs contribute to a more stable and responsive driving experience, whether you're navigating daily traffic or pushing your car on a track day.

Eibach has engineered these springs to provide a balanced approach to lowering. They typically reduce the ride height by about 1 inch in the front and 0.8 inches in the rear, creating a more aggressive stance without drastically compromising ride comfort. The stiffer spring rate works in conjunction with your existing suspension components to keep the tires planted during spirited driving, giving you more confidence when taking corners. This kit is a popular choice for WRX STI owners looking for a tangible upgrade to their car's handling characteristics.

When installing the Pro-Kit, you'll find they fit right onto your factory struts. While these springs are designed to work with the stock suspension, many enthusiasts pair them with performance shocks for an even more dialed-in setup. This is a solid option if you're looking to enhance your STI's performance and visual appeal without going for a full coilover system.
