Topic: Roll cage padding

Lemons noob here, quick question about cage padding.

Hoping that the links below work, how perfect does cage padding need to be to pass tech with reference to joints? The pic below are just extra little pieces I had from other cuts...didn't know if it all must be covered to pass or if this will fly. Drivers footwell shown...Thanks for the input!

Re: Roll cage padding

Basically you want to cover every bit of cage that any bit of your body can possibly reach.  Keep in mind that parts of you like your neck can stretch ridiculously far in a big wreck.  You want to use the high density padding (non-SFI high density is a bit cheaper) at minimum anywhere your head can hit.  This pool noodle stuff you have will pass but if you ever need to put it to use will wish you had the high density stuff.  What you have also degrades a lot faster than high density.  I don't like to leave any cage exposed to my pink little bod so at those points where the cage tubing intersects I will notch the padding for the intersecting tube so there is padding covering the intersections.  As to whether this will pass tech I suspect so but since I've never left tube exposed like that I wouldn't know.

Rollbar Padding. All roll cage tubing must be padded with high-density rollbar padding wherever a driver may contact the tube–head, knees, elbows, etc.

According to the letter of the law, the padding MUST be high-density, the stuff in your pictures is not high density and will technically not pass. However, you will see that ~95% of the cars at any given race only have high density padding where the helmet will hit the bar(s). For all other places, they often use the low-density stuff. I'm guilty of this stuff myself.

However, at the last race (October), I was told to replace all the padding on my door bars with high density padding. YMMV.

Regarding the joints and fitment, they've never seem to be that picky or critical. Your fitment looks great to me.

Re: Roll cage padding

I prefer the high density on that vertical section, one piece from the floor to the dash bar, and the same stuff on the bottom of the dash bar.  As mentioned, also use the high density anywhere your head can hit.  The rest with high or low as you feel fit.

It appears your hoop support has some grinding on it where your door bars attach as that is a 'no-no', and what's up with that spreader plate?

Re: Roll cage padding

Just imagine your ankle bone hitting that exposed vertical bar at high speed.

High density covering everything is the way to go

Re: Roll cage padding

I think all cage padding should be this
Longacre Racing's high density roll bar padding offers the maximum in energy absorption and flame retardation. Used by many Sprint Cup and Nationwide Series teams, this roll bar padding will not drip or melt in the event a fire does occur. Longacre High Density roll bar padding is self adhesive (pre-taped), for a quick and clean installation.

All other padding's is just  like foam gasoline

Re: Roll cage padding

FWIW, all SFI 45.1 roll cage padding is rated to be flame resistant and wont drip in fire.  That's not specific to Longacre.

Re: Roll cage padding

Don’t trust that it’s self adhesive. It’s a nice idea, but some zipties keep things in place better.

just copy and pasted  the info, there is the interview of the guy from the Thompson race Champ when the Miata caught on  fire saying that the cheap foam was on fire around him and dropping on to him as he fight to get out of the car.

Re: Roll cage padding

Which is why you should consider buying SFI 45.1 rated padding and not un-rated pool noodles.
