To do a good job, you have to cover just about everything. The padding/carpet (plus the spare) damps a lot of the noise from the spare tire well, so skimp there if need be.

Some members have reported that doing the doors makes a big difference.

There are 3 layers of sound insulation on the wheel wells.

+Dynamat
+Frost king

I don't think adding more will do anything. The tower connecting the shock braces doesn't seem to be a source of noise it isn't close to the tires etc.

But thanks for the tips!

Covering the entire trunk is silly, that is not the right way of insulating, I did that on another car and it was quite pointless. I decided to go a more strategic route this time around.
