I have a 99 996 C2 i noticed the other day while washing the rims that the suspension looked aftermarket..here is a few bad shots of it...its eibach i know that, but the car doesn't look lowered...not very familiar with this car but can anyone tell what the suspension is? havnt got it on a lift yet to examine so figured i would ask.

ride height rear

That looks like it could be Bilstein as well. I know that they use a yellow paint on their shocks. Koni might be another option as well. Nice color by the way, is that Ocean Blue?

 

Looks like HR spring and a Bilstein shock..And it is lowered trust me
