SFI roll cage padding.
I put this in my car it's off center non sfi, got it from eBay but it's from kirkey, it's soft, I just angled the more padding toward the inside. Hope they don't have a problem with it when I go to the track but will cross that if they bust me on it, mine like yours will be street driven as well. Going to zip tie or in place once it's all set and ready. Will probably have tp get the sfi ones once I take it to the track.
