Can I use pipe insulation foam or pool toys as rollcage padding?
No. Rollcage padding is special impact absorbing material and should be fire retardant. The typical foam padding is also usually eccentrically bored to allow extra thickness in the right direction. Padding should be installed on every bar in all possible locations of body contact. Rubber strips such as Ensolite is also used instead of Ethofoam, but must be 0.5″ min thickness. There also exist a more denser type of rollbar padding called BSCI that is supposedly more effective for high speed impact than the “insolation” type of padding. After doing my own reading, I would recommend using this type of padding instead. You can read for yourself here.
