mountune’s sport spring kit was designed to make the Focus ST handle better not only on the track but also ride comfortably on the freeways without overpowering the OE shock absorbers. mountune demanded an advanced ride quality that is only offered by a true progressive rate spring. The outcome of countless tested miles on numerous British “B” roads and the famous Nordschleife is the ultimate spring upgrade set for the Ford Focus ST, not only offering performance it comes with an aggressive level stance.
Please note these are for 2013 model year application only. Ford has changed the design on the 2014 model year Focus ST front strut for vehicles sold in North America, requiring a revised spring design.
