HP, how does this ride vs. stock? I'm considering AST but I don't want to lose a lot of the ride quality on the street. I race so I don't intend on tracking this car much. Mind telling me/us what the spring rates are?

With proper spring rates the AST ride is about the same as stock but with more control. Damping force is generated very quickly with the ASTs and you can get away with slightly lower spring rates for comfort.
Spring rates will be tailored to each individual. You can also see the rates stamped right on the springs in the photo.
