Dr. Mudhan,
I hope you don't mind I am posting in your thread without your permission. But your thread really became an encyclopedia for ANHC (All New Honda City) so I think it would be good to have information in one place rather than scattered at several places.
Mods:
I have forgot to mention one mod that I already have done is that I have upgraded the tyres on my car. Currently I have Michelin XM2 195/60/R15 on my car. I clocked ~10K Kms on these tyres. I am really satisfied with this modification. XM2 is far far better than my stock Good Year. Good Year was very noisy on highways with >80 KMPH. XM2 is really silent and comfortable too. I am not happy with the ANHC's suspension system, at low speed passenger will feel each & every pot holes & bumps on the road. With XM2 it was greatly reduced and now ride became pretty much smooth. It performed really well in rainy season too. There is little bit body roll while cornering but I am ok with that.
Horn/LED light for cabin:
Recently I have upgraded horn. My car came with single (poor) horn. It was really smaller than what now a days comes in bikes (see in image). Stock one was from Hella. I have upgraded to Minda Trumpet (Skoda type) dual horn. I got it and fitted it from local auto accessories store. For horn, relay & labour, I paid 750 INR. I have also fitted LED in cabin dome light too from the same shop and paid 150 INR for that. I am very much satisfied with the performance of horn and LED light in the cabin. I went for single PCB of LEDs in the cabin, as of now I am satisfied with the bright white light. It is very much brighter than the stock yellow bulb. Sound of horn is really sweet. Usually I avoid to honk unless it is really necessary and safety concern.
Chrome plated handle cover:
I have tried to find it from the Indian online store and local shop but I didn't find it so I have ordered it from aliexpress and seller had already shipped it so its on the way.
Still ORVM cover with indicator and chrome plated grill are pending. I have enquired the local shop and he said he can order the chrome plated grill and quoted the price of 4K. If I don't get anywhere else then I will ask him to source it for me.
Sound Dampening:
Has anybody yet did sound dampening in their ANHC? If yes then please share the experience. If you know the DIY information then it would be good. I am also consedering sound dampening for my ANHC as DIY. Is it really make the difference? I want it to reduce the outside noise and not specifically for any music system.
