I did sound proof my vios on fender n floor using dynamat which cost me total damage Rm2500 n change my tyre to michelin ps3 another damage of RM980. Conclusion is dun waste ur money. If u really can stand the noise... change ur car. Haha!!!

Anyone here encounter Air-con magnetic clutch problem. My Vios was bought in May 2008 and just over the warranty period which is May 2011. Air-con magnetic clutch break down n calling Toyota to complain as ur so called Toyota quality part only can last for 3 yrs ++ but they still refuse to replace for me. So change it outside for RM450 Denso Original. Nowadays Toyota qc really SUX. During warranty period rear absorbers leaking and change it for foc. Then now is Air-con magnetic clutch. Wonder wat is next?

Dun waste ur money. I have done RM2.1k sound proofing using dynamat on floor, door, little bit on dashboard, insuflex on wheel arch plastic... all uselss. Still a noisy car i ever had. If u wanna know does it helps... i would say yes but only about 10% reduction. Save it for ur next new ride.

Today just realize tat Vios E come v pioneer HU n black interior. Aaarrrggghhh!!!

By the way it really makes no point to differentiate it is J, E, G or TRD as I spent RM2.1k to do the soundproofing on floor and door at GLS Auto Subang and it doesn't help to keep the cabin silent (no much different between b4 n after). Noise still loud like racing on the road. Tyre noise wind noise tis noise tat noise. In the end I just accept that it is a noisy car till I can change a new one. Don waste any of ur single cent n hope that it can reduce the noise!
