i currently have cheap coilover sleeves with tokico blue's. The tokico's are really old and the car is riding like crap. I am thinking about gettin a set of kyb agx's with Eibach Springs. I am wondering how low is the lowest i can go with a set of eibach springs. What are their heights? and where can i find a set for a decent price. If i decide to get this set up do i need to buy any kind of new bushings or what?
