H&R RSS Coilovers are designed and tested on the Nurburgring. ThereÂ’s nothing left out in the design of the RSS as they are geared for heavy performance use. They will significantly reduce the WRX STI's body roll and improve it's handling way beyond what any factory Subaru suspension can do. H&R uses their fully threaded shock body design and exclusive dynamic damper technology to make this an ultimate high performance setup.
