Summit doesn't have any specs and I can't find much online. The only info I did find was that they BOTH are about .8 drop in the front and .5 in the rear. If that is the case then what is the difference? MY car is dropped 1.5 now and its too much. The ride is harsh and bigger wheels won't fit.

With one of the above springs will my ride improve?
Will I be able to get 17x9's on the back and 17x8's in the front?
WIll the be a b***h to install?

The front B's are progressive and the C's are linear as I recall.

Also, prepare for more of a drop than advertised.

the b springs are about a 3/4 inch drop and the c's are 1 inch I just put the b's on my 89 and it doesnt seem to ride to bad. what year is your stang? 87-93 you'll need a coil spring compressor..94-up they say you don't but not sure on that

Get the "c" springs and cut one full coil off the rears. very rough ride with no body roll. I love it.
Heres my car after I installed them

Check out the chart on this page. This is all I found. According to this, they are the same drop.

What does the difference in spring rate mean?

The C's dropped my front 1.5in and the rear about 1in. Be warned- with the C springs you get numerous "kidney shots" while driving. I tried Bilsteins to no avail. Eventually I went with the HR sport springs _ same EXACT drop with much more comfort.

i was wondering that too when i was shopping for a set last week for my 86 gt vert. someone on here with a black 87-93 gt vert had a pic of their car with B springs and it had the look i wanted so i ordered a set of those.

i noticed many items summit has listed that were FRPP parts and had similar items listed and not enough info to tell them apart. like posi rebuild kits from FRPP, you cant tell from the description what the real differences are. i dont know if its summitt or FRPP that needs better descriptions.

I have B springs and it's a pretty rough ride on some of these NC roads.
