Our Instapak 65 expandable foam option is for adding strength under your rear seat delete panels for extra support when carrying heavier objects on top of the lower panels. It also helps with sound deadening if you are worried about an increase in noise from removing the rear seats and protects other components that may be installed in that void area. This foam expands in seconds to fill odd shaped areas. We include 2 foam packs with each purchase. One kit provides two expandable packs, one pack for each side of the car under the lower panels, however using a total of 4 (2 kits) is recommended for maximum effect to fill all areas of the void in some cars with a larger area.

Not required for Fiat 500, GTO, Gen6 Camaro, or Scion IQ, as those cars do not have a void that is necessary to fill.
Vehicle pictured is a 2013 Ford Mustang
