i did the subframes on my car (97 gt) didn't notice much difference.. i guess its a bit stiffer in the corners but nothing spectacular!
id do them on the cobra, but you might want to check... they might already be there... i think they put them on the bullitts and i know they put them on verts from the factory (sn95 anyway)
if you want some crazy subframes check out www.kennybrown.com , their system is awesome from what i've read.....
