H&R 15-21 Subaru STi Sport Spring

When you're looking to give your 2015-2020 Subaru WRX STI a more aggressive stance and sharper handling, H&R Sport Springs are a popular choice. This kit includes a set of four springs, designed to reduce the gap between your tires and the fenders, giving your car a lower, more streamlined appearance. They also lower the vehicle's center of gravity, which helps reduce body roll during cornering, making your STI feel more planted and responsive on the road.

These springs are made from 54SiCr6 spring steel, a strong and resilient material that's shot peened for added durability. The progressive spring design is key here; it means the springs offer a comfortable ride during normal driving but stiffen up when you need them to, balancing ride quality with improved handling. H&R manufactures these springs in Germany, and they are their best-selling product, often considered a go-to upgrade for many Subaru owners.

Installing these springs is a straightforward way to change your vehicle's suspension. While they are designed to work with your stock shocks, you'll want to refer to the manufacturer's installation instructions for the best results. Many enthusiasts find that lowering springs like these make their car more enjoyable to drive.
