Energy Impact Systems (EIS) is a revolution in the two-part foam seat insert design, providing a ready-to-use seat in approximately one hour. This is a kit that has everything you need to make your own custom poured seats.

Product Details

BSCI has implemented the use of EIS W50 SFI 45.2 Approved foam in molded seating applications where ultimate fit, comfort and most importantly, where safety is desired. EIS W50 is used widely in the motorsports industry for energy management in head impacts. This foam technology has enabled BSCI to develop the use of this same material for use in molded seat inserts to help manage the forces exerted on a driver's body during crashes. Seat inserts molded from EIS W50 are inherently self extinguishing when fire becomes an issue.

Not only does the foam provide impact absorption during a crash, the material also serves to offer total body support during the normal running of a race. Because EIS W50 is a liquid when introduced to the mold application, it offers a perfect replication of the driver's body unlike using other materials such as foam beads which are solid in nature. Where beaded seats are already present, EIS W50 can be used as a layer between the bead and the driver in order to finalize the perfect fit.

Advantages over 2-part foam systems:

  • EIS is tested to rigorous impact and flammability standards to conform to SFI 45.2 standards
  • The slow foaming rate gives the occupant more time to position their body in the seat
  • EIS is a resilient material that does not require replacement after impact

Advantages over beaded seats:

  • EIS is tested to rigorous impact and flammability standards to conform to SFI 45.2 standards
  • No costly and difficult to source tools needed (e.g. vacuum pumps)
  • Time is of the essence in racing and other occupations, and with a cure time of five minutes, EIS completion time surpasses that of beaded seats.
  • EIS begins as a liquid, allowing the material to conform to every crevice of the body and ensuring accuracy of the mould. This allows for maximum comfort and support which is to be expected by the occupant. Beaded seats do not have this characteristic.
  • EIS is a resilient material that does not require replacement after impact


Kit contents and sizes in the Specification tab. Note: Electric carving knife is not included.


  • Small: Perfect for a customer searching for additional lumbar or hip support in an FIA or Aluminum Racing Seat.
  • Medium: Ideal for when more support is needed then the Small size can provide. Also ideal for replacing the lower seat cushion (for example, to sit lower in the seat) and back cushions.
  • Large: Ideal for when complete padding is needed up to the driver's shoulders. This is the most common option when a driver change is needed, and a smaller driver needs to fit into a larger seat.
  • X-Large: Similar to Large, but with enough material to cover additional cushioning around a halo/head-restraint style seat.
  • XX-Large: Needed for larger jobs, such as creating padding in a seat that is built into the chassis (Formula, Prototypes, etc.)
