The second soundproofing are the wheel well or underwheels. This should help to reduce sound coming from the wheels.
I used 3 types of materials.
1) soundproofing
2) sound absorption
3) sound deadening
Note that I am not a professional. I am just doing this for my own DIY. I do not claim to be using the best method or not. This is just for entertainment purpose.
