Autofoam

A concept I learnt from hi-fi as I had to place sand into the hollow stands to absorb vibration. That concept is now applied in car customization. AutoFoam, a shaving cream-like foam is used and hardens in a few minutes due of a chemical process. I chose the sports package and forgo the comfort package for lack of fund. Four mechanics worked non-stop for 3 1/2 hours. 4 door sills plus the A and B pillars  were "autofoamed". The comfort package concentrates on the chassis but that would take another 2 hours since the front seats must be removed. It takes 24 hours for the  autofoam to dry but the effect was already felt the moment the car reversed out of the shop. She felt structurally solid. I don't think autofoaming improves road handling like what a set of adjustable coilovers does but what it does well is absorb the nitty gritty shakes/wobble and as a package strenghens the car's structure.
