I believe the factory specs call for T or even S rated tires for GS, so this is good enough. Any case, you probably will never drive so fast in real life. Of course, the higher rates rates give extra margin of safety in case of underinflated tires (nail, etc).
Even more important than the speed rate, though, are such things as dry and wet traction and cornering, resistance to aquaplaning, and, probably, snow traction - depending on where you live.
Next question is the resistance to the tread wear. And, last not least, ride comfort and noise. This very personal.

Yes, the two parameters are different, but in practice tires became hot when running at high speed, and this means the performance tires are designed to resist the high temperature.
I read a lot of tire specs while shopped for replacement tires for my 98 Malibu. All "S" and "T" speed-rated tires I checked had the "B" temperature rating, while the "H" speed-rated tires (130 mph maximum) got the "A" for the heat resistance.
By the way, I bought FireHawk SH-30 for the Malibu. Not for its temperature rating, but for outstanding wet handling and resistance to hydroplaning.
I like the tires very much and most probably will install them on my Regal after the OEM tires will wear out. Other users like the tires as much as me, and praise them even better than the much more expensive Michelins:
Though, the SH-30 are performance tires, not touring one. They do not isolate the driver from the road pavement imperfections as much as the OEM tires do. Fine with me, but this depends on personal taste.
The user survey for touring tires is here:
