I run them,I went with them because the fronts were progressive,and the rear was specific....drop the car about 1.5'' front,and 1 1/4' in the rear. Ride quality feels good,not bone jarring......just right for the street imo. I have pics if you want.
The ride quality with the B springs is alot better than the C springs
because with the C springs the ride is harsh.I hope you are running
a decent set of shocks and struts with your B springs.
The drop with the B springs is about 1.5" all the way around but,
the front should lower more than the back because those springs
give you a slight rack look.
