Thanks Essarr for the valuable information. Have you upgraded the tyres & done sound dampening at the same time? I am asking this to just verify how much difference you have felt by doing sound dampening only? I believe you have done it yourself. Have you taken any pictures while doing it? Have you made DIY steps? I know I am asking too much but it would be really appreciated if I get more information on that. Mainly I am seeking answer for the question is it really worth for ANHC?
Soundproofing was done by my garage guys (but I was present) because I was also getting Oznium under-door courtesy lights installed at the same time, where the door panels had to come off. Sorry no photos taken
Soundproofing can be a DIY project, but needs a helping hand to get things aligned properly. As for the sound insulation part, I feel it is worth it. As for the thermal part, I have to wait and see. In fact, I am considering soundproofing the firewall and wheel arches whenever. Right now my priority is finding Bilstein B4 shocks for all four corners (understand they make for Fit and Jazz, but not City).
