ok so i was at my local junkyard a few days ago and there was a 99-04 mustang convertible and i knew something had to be better structurally underneathe it since it doesnt have a roof, so i got under it and was able to unbolt some subframe connectors and i got them at the house now, my question is should there be any problem of them going on my coupe, other than my coupe im sure they dont just bolt on, but if its pretty much the same as all the aftermarket ones than i saved about a 100$

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 .

A good set will add around 25 lbs to your car but well worth it , makes it a totally different ride .

The stock ones used on convertibles, Mach 1's, Bullitts and pretty sure Cobra's as well aren't really subframe connectors so much as they are floorpan stiffeners. In order to be subframe connectors, they would have to be long enough as to actually connect the front and rear subframes. And in order do be effective, they would need to be constructed of thicker steel like aftermarket sfc's are.

The only useful added bracing that was specific to convertibles is the K-member brace. Not sure if it would be worthwhile to stick one on a hardtop car, but they do function well as a skidplate to protect your oil pan if your car's been lowered, haha - mine definitely has a couple scars.

If you're on a budget then go ahead and put them on but as mentioned above, there won't be much of a difference...save $150 and get the MM subframe connectors.

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.

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 .

Ever plan on going around a corner? or accelerating with bravado?

;)

I learned I REALLY needed SFC's when at autocross one event had two skidpads in one course (big O shaped corners where you go around the full circle). The skidpad was so hard on my mustang, chassis flexing, one front wheel skipping around while the other one stayed relatively planted, the ungodly understeer.... SFC's are absolutely worth the money.

Also when my car got 4.10's I lost all ability to launch energetically without roasting the tires and wasting the power, another sign the chassis wasn't doing it's job.

Coupes are stiffer, but they absolutely still need the help.
