Im looking to get suspension as my first upgrade for my car. On myracebikes I always bought the shock as a Peske or Ohlins unit but cars have a little more options for spring/shock combos or struts.

My question is that I can get Eibach at wholesale cost(what the manufacturer sells them for)through a relative. Im looking at two options right now.

A-purchase eibach lowering springs at cost and get bilstein sepperatly(tire rack).
Cheap but I can't change the ride height. But I dont think i'll ever need to anyways.

B- Get eibach pro coilovers.

Im just curious if the eibach coilover would be a big change over the spring/bilstein combo? Its a little squirrly now but it does havelow performance tires. I have no plans in the future for getting wider wheels just gripper ones than the ones I have.

 

Also does anyone know if the ride height adjustment for the Eibach coil overs is in the shock body length or done by lowering the preload(crap).
