Who has Comptech coils? Do they lower the car a lot? By how much?

 

I've never seen a set up close. Does the inside diameter measure to be 2.5"? If so, I'm sure you could use some ERS springs.

 

I am not sure of the diameter of the Comptech as I didn't have a chance to measure them when I got them installed. But they do look very similar to the GC.

Why not simply call Comptech or Eibach and find out for yourself?
