Just bought some Ford Racing B Springs

I know I should probably search this, but terms with only one letter are left out. So here goes.

I bought a set of used springs yesterday for $80. He thought they were 1.5 drop, but had no idea what brand they were, came with his 95 that he had already sold.

After a little research from the part numbers printed on them, it seems as though they are Ford Racing B Springs.

Anyone have them or have any comments for them??

I got a set of B's for my son to put on his 98GTa couple years ago from Summit Racing. He seems to like them, rides like stock.
About 1.25 drop and progressive rate. No need for CC plates.
