Subframe connectors?

[Treecutter]

I see that they are sold to fit the 05-09 cars but never see anyone recommend adding them. Are they needed or are they a thing of the past?

General consensus is not needed on this chassis

I would say not needed until you get to a serious power level that you need to solidify the chassis some.

I have been putting on sub-frame connectors on all my Mustang's; Fox, SN95 and S197. Any car that is unibody benefits from having its chassis connected. I run my cars hard and most make decent power, so having the frame rails tie together (welded) is a big plus for me. They track straight, alignment is perfect and launch properly. Obviously, suspension has a lot to do with it too...

For a couple of hundred bucks, you get extra ridged (especially if you own a convertible) and less chance of distorting the frame, wrinkling the floor pan or pulling out a control arm from torque box. Also, might aid in a collision...

Either way, opinions are like... LOL

The key is welding them in and welding them in properly.

AGREED

I have a chassis shop do all my welding. Prep, grounding and the actual process in welding sections and even around some sensitive areas are all very important.

Always been interested in welding, but not my specialty, so I farm it out to the experts.

Why? Nothing wrong with this weld? LOL!

Godzilla can weld better than that... LOL

Put some JB weld on there... Funny I have actually used that stuff with decent results, so let me not bad mouth it.

I used steeda chromolly steel subframe connectors, bolted and welded. That, plus a 1/4" thick BMR rear tunnel brace...+ safety loop. Then a steeda rear STB, in the trunk, welded into place. Back end of car is more..'solidified'. Then in went the eaton - detroit tru-trac LSD and also the whiteline watts link, and also the DSS-DS. Last item that went in was the steeda CM jacking rails down each side. Ok, now everything works the way I want it.

If you look closely, the S197 has a rail going down the full length of the rocker. Its a pretty solid piece. Unlike prior year, pre 2004 mustangs. Its like Ford realized the weakness and redisigned the 05&up chassis.

unless you have a convertible, they're not needed. I have a vert so they greatly benefited my car
