[QUOTE="Lee36328, post: 67710, member: 113"] I don't hear anyone talking about crumple zones where antiroll bar and struts bar are concerned... Yes, the engineers made the car with certain parameters in their calculation and doing anything to the car will alter those parameters. The same can be said to : 1. changing the airfilter 2. changing the engine 3. changing the suspension 4. changing the brakes 5. changing the exhaust 6. driving with a bad mood 7. ad nauseum In short, if you alter anything, the calculations are out. Secondly, I would be mightily impressed if the lowly foam is stronger than steel to the extent that the crumple zones are shifted inwards, in which case, I would feel safer, since I've effectively strengthened the passenger compartment by foaming the A and B pillars... For the aggressive driver, an foamed car will actually need the crumple zone less since foaming helps with handling. In the case of the Alfa 156, 1. insulation is not the main benefit of the foam. If you foam a noisy lorry, you will unlikely to notice any improvement in noise insulation 2. I don't drive a 156. It worked beautifully on my e36 though... Sit in two cars of the same model, foamed and unfoamed. Beats hearsay and imaginative theorising anytime for accuracy. Cheers! [/QUOTE]
