I own a 2000 Integra w 18" I want to drop it but i kinda rub already sometimes. What do i need to prevent this while still lowering my car. I have some Eibach Sportline Springs but afraid to install them unless i know i am doing it right.

18s are about as big as anybody should go on an integra without rolling the fenders and thats without a drop. If you're already rubbing over uneven pavement then dropping an inch or two will guarantee some heavy rubs especially without lowering shocks to reduce spring travel.

You cant lower it with wheels of that size.

well he could... but it wouldnt be fun
