Adding sound deadening materials to these cars makes such a huge difference in ride quality.
I installed the MGF / TF kit from NKGroup (which includes a replacement pad for the rear shelf).
I also added a bit of extra sound deadening adhesive material inside the doors. It makes the car feel much more refined and comfortable. The doors close with a clunk instead of a tinny ping. It is amazing what some material can do.
In addition to sound deadening the floors, you may also want to consider installing some foam mat material under the footwell (I used some foam 'puzzle' tiles that were cut to size). Just make sure it is dense foam. In addition to making things quieter, it also has the benefit of raising the level of the carpet to solve the 'pull away' problem around the door edge. It is a really elegant and simple solution to a very common problem 

THANK YOU! 
Vindication! It truly does enhance the ride and thank you for confirming!
