FRPP spring question

looking to lower my car but was wondering what the diffrence in the b and c spring is on the ford racing spring and how each ride would feel like.

I had c springs on mine, lowered it a bit, but not quite as much as some of the other aftermarket springs. You will need to invest in new shocks and struts, cause the stockers will not hold up for a while. The C's will lower the front end a bit more than the back, some people go ahead and cut a coil off the back of the C's.
