Caster/Camber Plates?
 

Soon I will be installing a set of Eabach Prolines along with KYB AGX adjustable shocks/struts. Will I need caster/ camber plates? I have a 2004 GT conv. Thanks.

Sorry, I meant Eibach Pro- Kit.

You shouldn't cause the drop is less than 1.5". Thats the same setup I have and I don't have plates. I will probably get them in the future cause they are good to have and I will get coilovers. You should be fine though. I ahven't had any problems.

I always recommend getting CC plates (Maximum Motorsports only for 94+). Many people luck out and get a solid alignment without them but you'll always be pulling more negative camber than spec.

It's 200 bucks for all the adjustability you'll ever need to keep the tires from wearing too fast. Nonetheless... no you don't "require" them off the bat.
