Two things I've picked up with aftermarket brake pads over the years in general not just the GS....
Make sure the backing plates are the correct size, some brands I've had to relieve with a file to make sure they move in the caliper properly. If it catches then generally it will make the brake drag (or stick on).
Be wary of cheaper pads when they get low on friction material. One way they save $$ is to use a thinner backing plate. If your rotors are a bit worn, backing plate a bit thinner & the pads are worn out there is a danger that the pads have excess tolerance and can drop out of the caliper. I've only seen it happen twice but it does happen....
