I know these questions have probably been asked a million times, but I'm going to be getting lowering springs soon and I'm having a hard time deciding whether I want to get the eibach pro kit, or the H&R super sports, I've heard that with the pro kits sometimes they sag in the back because they're an equal drop, I definately don't want this. So would I be better off going with the H&R's? because they are lower in the front by 1/4". Which ones are a better spring???
