H&R springs for my car

I've had the H&R Sport springs for over 4 yrs and they just stiff enough without beating you to death on a dumpy roads I think. They lowered my car 1" which is exactly what I wanted if that helps you any, the
The H&R Sport springs are a Dark Navy Blue not the silver as they told you,unless someone has painted them for some reason,and they will say H&R on the spring.
This should give you a good idea of the H&R springs.

No silver H&R spring were built for the Mustang. If they have been repainted, run!!! Well run anyhow if they are silver...

Sports with a good sport shock is going to really bump up your performance and give you a lot better feel but be daily drivable..
