So I have a 2012 GT with the Brembo option. As I understand it, my car has stiffer springs and different shock valving as compared to a non-Brembo car. Comparing my car with my buddy's non-Brembo '13 GT, it's obvious mine rides stiffer. So how would these K spring compare in stiffness to what I have now? Similar?
These will work well with your brembo package. The ride is a bit stiffer, but it is still very compliant for daily driver use. The handling improvement is greatly improved as well. You should be very pleased with them.
