The H&R 54460 is a sport spring set for the 2008–2011 Subaru Impreza sedan and hatchback, and it lowers the car approximately 1.4 inches in front and 1.3 inches in rear, per the manufacturer's application listing. Like all H&R's products, H&R Sport Springs are 100% made in Germany and use only the finest quality materials and precision manufacturing. Germany is also where the manufacturer's springs get their epoxy powder coat, and the manufacturer backs them with a limited lifetime warranty.
Compared with stock coils, the manufacturer ties a lower center of gravity to sharper handling and less body roll on this platform. A cheaper drop spring may match the height but offers no warranty backing and no documented German manufacturing, which is where this kit earns its price for a street-driven Impreza that still needs to corner cleanly. For a 08-11 Impreza sport spring, the lowering figures and warranty are the points to compare against any alternative.
Trim coverage is the main fitment question. The manufacturer lists the sedan and hatchback for 2008–2011 without a trim breakdown, and details vary across sources on WRX and STi trims, so confirm your specific trim with the manufacturer before ordering. Owners on user forums warn that Only 2008-2014 Impreza specific springs will fit. 2008-2014 STI springs are too short. Do not substitute STi springs to save money on a sport-spring install.

Swapping lowering springs means working on the front and rear suspension and compressing the factory springs, so plan on a shop bay, a jack and stands, and a proper spring compressor. Owners on user forums advise against using 2008–2014 STi springs as a stand-in for this Impreza kit, so check the part number against your car before you start. Plan a wheel alignment after the install, and confirm any torque specs and install steps with the manufacturer's install sheet.
