A good set of welded in full length subframe connectors are one of the best mods for these cars , those flimsy short bolt-in factory pieces went straight into the garbage .
Probably not as necessary on a dd mild street driven coupe but if the car is being lowered the stiffer suspension works so much better when the chassis is made more rigid with the addition of flsfc's . The Kenny Brown system adds jacking rails and a side grid to stiffen things up further if your building a corner carver .Is there really a reason to put subframe connectors on a coupe?
My 98' coupe is WAY more rigid than my 95' vert was.
My coupe doesn't even have a strut tower brace or k-member brace like my vert did. A lot of people claim the strut-tower brace doesn't do anything, but I'm sure it takes a LOT of stress off of the struts/towers in high speed turns.
