I think you will find it is just for the springs. I read in VW Driver that a guy fitted the sports suspension upgrade (just the springs) to his Passat, which induced rolling and nausea for his passengers. The Gti shocks are of a different design to the 130 shocks (much firmer with less rebound). If you specify the sports suspension when ordering a non Gti new, you get the Gti shocks as well. If you buy the sports suspension as an aftermarket upgrade you just get the springs.
