Just bought a 95 Cobra 2-top and it has Eibach Pro springs. Eibach's website says it has 1.3" drop front and 1.4" drop rear. Is this enough drop to have problems with "bump steer"? And do I need caster/camber plates to prevent any odd tirewear?
That shouldn't cause bump steer problems. It isn't that far of a drop. If you have had the car aligned since the drop and it continues to wear the tires, yes C&C plates might be necessary to fix the problem.
One other issue with the springs, the shocks are stock. When I go over bumps or road heaves the springs seem to over extend. Kink of tosses me off the seat. Makes me think the car needs upgraded shock to handle the lowered springs? Something with more rebound dampning?
