Bhai, u have sold the original steelies and put these ones which makes car odd. if u would have stuck to the original profile, there would be a lot of difference in ride. anyways u have done it.
Secondly, dont go for the vitz ac setup. they will take out your ac blower setup and put the vitz setup which needs cutting and a hole will be made in the firewall. the vitz setup is too big and will hit the feet after installation plus your heating system will be removed completely.
as per them the cooling will be like "sheehso per pani jama hojaega" but dont go with that philosophy. dont ruin your car further, get proper things installed.
Third most, u r missing rubber plug from your floor pan, get them all installed as they take water and dust. your car needs serious undercoating as the pictures says. there are many open spaces.
forth, get the pil removed as soon as possible and dont drive the car with overfilled oil as it will damage seals.
