The WRX coilovers were measured at 3.5" of front stroke and 4" of rear stroke, and all of the Subaru coilover offerings have similar travel specs. Those measurements are from full extension to the bump stop.
As far as spring rates go, please send us a PM with your year and model of Subaru and we'd be happy to advise you on spring rates. Our recommendations will differ for each car and each driver's preferences.
