The RCF lowering springs works for the GSF like the RSR or Swift.
Ive called Swift to see if the RCF springs will work on the GSF and they stated that it has not been tested on the GSF so they don't recommend it and also they don't even know if there will be testing the RCF springs on the GSF or coming out with a diff model.
