Install oem steel rims or oem alloys because my experience is that chinees alloys make car uncomfortable.
Then oem rims install YOKOHAMA advan Db v552.
Then if you want excellent comfort install softer but longer springs in back. This makes your car front heavy and make the ride smooth and comfortable. This technique is used by Toyota in Toyota corolla.
And currently i used this technique in Honda Civic Reborn 2010 by installing rear longer springs the car gets lifted from back and become more comfortable than our 2012 1.6 corolla gli.
