Which FMS springs, "C" or "B"?

[MTU 50]

I have "C" springs in my fox-body mustang and I picked them because I wanted better handling. The C Springs lower the ride height the same amount as the B springs, but C's have a 650lb/in spring rate compared to the B's stock rating of 400lb/in. The ride is worse with the C's, but I didn't care, because the ride was nothing to brag about with the stock springs. It says in the summit catalog I have that both C & B springs lower 94-95 cars by 1.125 inches in the front and 0.75 inches in the rear.

If I had your car I would definitely get the C springs, because I like better handling. However If you like how the car handles now and you want to keep a decent ride over bumps then get the B's.
