1. Yeah, but never seen them talking about those on us magazines articles and speed vision etc. Even when they are talking about big figure HP cars. As I said, it was a comparison between how many ppl cares about those in the states and back in asiaDave C ver2.0 said:Filling the door sills with foam is an old racers trick. To understand it, get an old paper towel roll tube and try to bend it, bends pretty easy right? Now go to Home Depot and get the expanding foam sealant and fill the tube with foam and let it cure. Now try and bend that sucker, bet ya can't do it.
It is useless to faom doors and fenders as they are not part of the basic structure. Foaming the sills/rocker panels can help a good bit but you have to consider any current or future wiring that runs through there.
PS: Did you know our floorpans (at least the G2) are already a honeycomg sandwich. Pretty stiff stuff.
