[QUOTE="DChong, post: 72155, member: 1316"] Hi guys, I am Desmond Chong from K L AUTO, the distributor for AUTOFOAM chassis stiffening & soundproofing foam. It is great to see so much interest & controversy on our humble product. My sincere appreciation to Lee for starting this great thread. AUTOFOAM is sourced from Europe from a major OEM supplier. It is a Closed cell structural foam specially formulated for AUTOMOTIVE use meaning it is designed to cure consistently & uniformingly in an enclosed space ie chassis. This is very important to ensure there are NO air pockets or voids in the chassis . It is non-hygroscopic--will not absorb or trap water. It is non combustible. In short, it rocks! Foaming a car is a permanent 1 time treatment.....trust me, we have tried removing the damn thing. It is IRREVERSIBLE. So getting it done RIGHT the first time is paramount. As to the topic of crash worthiness, below are some technical specs for the techies to chew on..... Density.........................................23 to 25 kg/cbm Tensile strength (DIN53455)........18N/ccm Shear Srength (DIN53455)........ 8N/sq. cm As you can see, AUTOFOAM is rigid not solid. It reinforces chassis structures but not to the point that the car is cast in concrete.. In Europe, US, Japan, automotive foam is used on crash repair cars to reinforce the weakened structures.The same formulation is used by major car companies in certain chassis joints and on the latest Alfas in the rear chassis to CUSHION shock & impact in the event of an accident. Internationally prepared Rally cars are extensively foamed. Japs foamed their Drift cars in every concievable orifice.....(.learning from Lee.) The areas we apply to would depend on the needs and requirements of the client. If one feels that foaming certain areas would compromise the crumple zone ,then omit it. But foaming B pillar & Side sills definitely improves cars integrity and safety. Car modification is a very personal thing. Some people would even go to the extent of putting Porsche brakes on a Airtrek. Some want their car to handle like a Go Kart.....go full works... AUTOFOAM, H&R, BILSTEIN,RACING DYNAMICS,AC SCHNITZER. ..Want comfort, go for AUTOFOAM cabin......from only rm 680 ...very affordable. So the moral, to each his own. But one thing is very clear.....AUTOFOAM works! BTW, the NECESSARY, the failed suspension on our mutual friends car was due to a over torqued rear strut bar.....they over tightened the top bolts. If anybody needs any more info,give us a call, u can PM me for the number or refer to the first page. Cheers, Des [/QUOTE]
