Mustang Maximum Motorsports Subframe Connectors Full Length Set 1979-2004 Installation 

One critical step that I think needs mentioning. Each subframe connector has a triangular shaped hole at the rear. After all other welding is finished, the final step is to weld this hole shut. The heat from the previous welding will purge all of the moisture out of the subframe connector. Welding the hole shut will keep any new moisture from getting into the subframe connector. If this step isn't followed, the subframe connector can rust from the inside out.

Just installed mine. Made a big difference. My doors are aligned now.

Installed these on my 90 coupe & one of best mods i made to car! MM products are top notch

I would mention disconnecting the battery before welding. It's easy to forget

There's a lot of stupid comments here about what should be done different or better or so on. Only so much can be covered in under 10 minutes, there's a lot of details left out of the video for the sake of time. MM sends almost 15 pages of very detailed instructions with this product. Please, please! For the love of Mustangs, read the instructions before you start. Read them as you complete a step and head into the next one. Read them before you go to sleep at night. Know them...before you end up trying to sell your effed up Mustang at a discount to some guy that knows how to fix it!

Great video! This looks like exactly what I want. Probably going to do this myself over the winter, but I expect it to take longer than 6 hours. Welding while laying on your back is a bit trickier :)

The dislike was a Camaro owner. Excellent video!!

Damn that blue sweet

Just installed these on my buddy's fox body. I am notoriously picky and slow and did this entirely myself. So, with that in mind, the time from rolling it into my shop to rolling it out was about 8 hours. I did not have a lift but did manage to get the front wheels on platforms and the rear on jackstands about 20 inches off the ground. A lift would have cut about 1 to 2 hours out of it maybe. I did have to mill out the seat bracket slots on one side to get the rear section of the connector to meet the frame. Be ready to fill some pretty large gaps on the rear especially if that area is damaged from being lifted in that area over the years. I also had to remove the exhaust system. The front drivers side had some super thin metal so I had to scab in some material to get a good weld. The rails were misaligned front to rear on both sides about 3/8 to 1/2 inch. So I tacked the front and just pulled them in a bit with a C clamp to get them in line with the frame. I am sure with cars of this age you will always run into surprises. Just be ready for this to take longer than you think.

Choosing this sfc over late model restoration's due to the end tubing being capped and it comes with the extra pieces to weld in, good attention to detail

Hi, thanks for the video. Will these work with a convertible?

Nice notch back

I’ve got a set of these but when I press them up to car the one end touches and the other end is down about 1inch from the frame should I just jack the connector up to the frame or bend the connector to fit?

I have a 92 convertible. I'm assuming thre oem ones are junk? Definetly a big difference from stock to full length weld in? Thanks

This may be a dumb question but once installed do they block access to the torque boxes? Say torque boxes need reinforcing, should that be done first?

What was the total time for install?

nice I bought the full length powder coated ones from you guys I'm going to get them welded. Any idea on a average price range that a shop might charge

I’m going to do this and had a question, would there be any benefit if I welded the entire seam that was resting against the metal subframe. Or is welding just the tabs fine and wouldn’t make a difference?

my floor board in the passenger rear where the feet go is a little rusted? what should i do?

2 things worth knowing: dont buy the painted ones especially the powdercoated ones. you have to grind off the paint or powdercoat to weld them and you will have to grind or sand about half of it off to weld and the stuff will still burn and smoke you out. guess how I learned that one... AND if your frame is tweaked at all, fitment is not fun. idk how my car is so messed up and still has straight body panels. neither connector lined up with the rear subframe. they were both a few inches off to the driver side so that means my car is bent in a right hand curve(don't know how else to describe it). and the driver side connector isn't sitting flush with the rear of the frame yet. I still got to finish that connector. also don't understand how the heck my doors open and shut at all let alone shut and open normally. none of the gaps in my body panels are right.

What is the exact paint used in this video ?

Question? Are torque box reinforcements still necessary if you install that particular type of long sub frame connectors from Maximum Motorsports?

My understanding is that these are better for jacking also.

If you have a convertible, do you have to remove the oem ones.?.

Why the red primer, over spray all over everything makes the job look sloppy. Otherwise great install

I love my bolt in ones from umi for the s197, sturdy and no welding, didnt want to disturb the factory paint, rust comes out then!

So if a person is to be welding these in, should the carpet be removed inside or are these not being welded to the floor pan itself at all?

What is the little piece for ? structural or for looks

Where to jack it up when the car has no suspension i toke all parts off

More foxbody videos!

I thought you were supposed to weld with the tires having weight on them?

What about welding helmet and gloves for equipment required

Never assume seat bolts will just come right out. Deal with those STEP 1.

Good video in general but to get the true effect of frame connectors they should be welded the full length. Also I would protected the guys car from overspray, jeez I’d be upset.

Is there any way to tell if your frame is sagging before installing the subframes?

No time to mask off anything lots of over spray nice.

yo the paint on the bottom would piss me off

Didn't cover proper orientation of the seat brackets, also not supposed to weld across the front or back edges of the subframe (he didn't but it wasn't pointed out). Also, for cars that may have or get an IRS in the future it's CRITICAL the rear is FLUSH with the outside edge. You guys should just do another vid and show these points on like a new edge cobra.

Bill sounds like Jimmy Kimmel.

These are not subframe connectors, they are unibody connectors, it doesn’t have a rear subframe, and they don’t connect to the front subframe, good video otherwise.

What the hell is the point of that stupid music? Totally annoying.
