Grill available at Mintgomery road, speakers any good kenwood/pioneer of your choice since you are going to install on the back board, which will require to cut the metal plate and the phatta will make noise if not properly fitted,,, for tyre best is Yokohama Db advin 185/65R15 or 195/65R15 ,,,, 195 makes the steering a very slightly hard, and might effect the fuel consumption (hardly 5% i think)but sure are very comfortable. i have 2 city (2010 and 2011) 1 has 185 tyre and 1 has 195, i prefer the 195 one for its comfort 185 is also good but itna maza nae ata,,, both tyre have almost the same price which is double the price of EuroStars, and 185/65R15 yokohama is a lot better then eurostar in terms of grip quality life etc but not as much in comfort as one would expect from a tyre with double price
