So i just Recently Purchased a Acura Rsx 05 and i want to learn more about it. the owner before me put BC coilovers on the car only 1000 miles, i must say the car rides rather bumpy any way to fix this problem. i just need guided in the right direction because i want to really take care of my car and i plan to make this car my project car. Ill post pictures later.

 

The ride of the car (mine is base model RSX 2005) is bumpy even without any modification.

 

RSX stock is a bumpy ride IMO. Especially if you live in a big city where roads tend to not be paved very well.
Since you have coil overs... If they are adjustable you can soften suspension. But this will take away from your performance. That's why your ride is bumpy because RSX is a sporty car. I don't know what direction to lead you into since you didn't specify your plans.
You just want to see horsepower results?
You plan to hit corners as well?
You just gonna hit the drag strip every now and then?
