Maybe slightly stiffer but not incredibly so. It rides closer to an SRT than an SRT does to a normal GC if that makes any sense. I have yet to feel this is too stiff (in some sports cars i do feel that way).
I've found on my TH that putting the suspension into soft mode, but with the other settings in track, it rides a bit better than my 2014 SRT but is crisper in all the other departments. That combo is good for me, as a daily driver. Plenty of fun with a nice ride.
If I ever want to haul even more ass in the twisties, I'll simply set the suspension back to track and have at it.
