Yes it will give an improvement. No it won't stiffen the chassis more than a well designed roll cage. If the cage only stiffened it by 11% then it wasn't a very well designed cage. It is not surprising that you can get measurable gains from using it, however I find it hard to believe that using this foam alone, they achieved 45%. The least stiff area for torsion in any monocoque car is through the cabin area (where the doors are). You can't get a lot of foam inside the sills and pillars, not enough to make a huge difference in this region anyway. You could however stiffen the areas either sided of this by filling the box areas behind the front wheels and in front of the rear ones. This could give noticeable improvements in stiffness as will seam welding in these areas. The down-falls with using it though is as mentioned before, possibility of panal damage when the foam is expanding/curing. risk of moisture ingress causing corrosion. And once it has started to corrode, I don't think it would be a great idea to put a welder near it. This is also a cure for some chassis squeaks too. [Report message to a moderator]
