What is everyone using for roll bar padding? What is the difference between the $40 a stick SFI padding and the $4 a stick roll bar padding?

What about the custom pads, do they limit your head movement / vision much?

I replaced the padding in my quay bracketeer this year, used the padding from summit and used a heat gun to warm it up to conform to the cage and zip ties to hold it w/o the Velcro backing that never holds it to the bars. Meets the sfi requirements and so far all the tech guys were happy with it at 2 national and 3 divisional events.

Did you use SFI padding?

Yes, it was the summit 45.1 padding. 3 different thickness, and tube diameter if I remember. As long as its sfi, why pay extra for a brand name. I used the thick one on the overhead bars and a thinner one for bars by shoulders.

Little off topic. I went with Garvin motorsports padding. About same as the ISP stuff but at 1/5 the cost and not a ton more than the cheap round stuff.

About 300 bucks and I had extra pad for behing and above head. IMO well worth few extra bucks for lot better stuff protecting my already very hard head.

Also used their seat insert kit.

I just put on some, let it set in the hot Texas sun for a while, then a heat gun and it worked great, I used SFI Jaz...
I tried some late last year, some off brand from a local shop, did not know the above and it snapped like a popsickle stick....The above would have helped but also think it was just old, on the shelf too long, really brittle....

Don't know IHRA rules but NHRA requires SFI padding for cars 9.99 and faster

You have to see the difference between the $4 pool noodle padding and SFI padding. The $4 padding is just soft foam, the SFI stuff is hard foam.
