Description H&R Sport Springs lower the AMG GT-R approximately .60 – 1.2” front and .40 – 1.0” rear. Reducing the fender well gap and lowering the center of gravity provides for improved handling and grip. H&R was founded by Werner Heine and Heinz Remmen in the 1970’s with a simple idea in mind; with improved suspension, vehicles would have more control and better handling.
