Great video! I agree with your thoughts on everyone else removing the back nut for the cobra bracket. What I did was weld some flat stock on the bracket and drilled a new hole to work with the factory nut. Your way works too! Straight to the point with no BS. Good job.

Hey boss nice video I have a question I’m doing the 2001 cobra swap on my 87 fox. What driveshaft did you use? Or am I able to use my stock driveshaft by swapping both ends? Thank u for any info
you can use the same driveshaft, it's a tight fit, but it will go in. Why are you swapping both ends? When you say "Cobra swap" do you mean engine and trans too? if you're swapping the engine and trans too, all bets are off, you're going to need to re measure and get a different driveshaft.
@@Sgt.Slides yes I swapped motor and transmission to a 2001 cobra. I forgot to mention I swapped out the differential as well ? Does anyone sell this custom drive shaft I’m having trouble with this all info is appreciated
@@EverythingpaintApplications so, since you are using EVERYTHING from the cobra, you're going to need to get your driveshaft shortened. If you can find a shop to do it, they will also tell you how to measure. Hit me up on instagram and we can chat more in detail about your driveshaft situation. @sgt.slides
before i had flares and spacers, i ras running OEM new edge wheels with 245's It was still too tight of a fit and i ended up ruining my fenders trying to roll and pull them to make everything fit. I actually had an appointment scheduled with a body shop before i decided to just chop it up and do flares myself.
it's a very tight fit but it will work. you may have to unbolt the subframe OR unbolt the trans cross member to give you enough space to slide it in, but it will fit. my drivedshaft was unmodified.
Been really considering doing this swap on my 1993 Cobra. Little confused though, which year stang and model is the proper purchase of the IRS to do the swap?
2001 to 2004 cobra all had it. 03 and 04 had slightly beefier axles and slightly different diff bracing, but they are all hard to come by, don't let the year be a deal breaker for you.
Hey, I've been watching your videos and was wondering if you would help me do my swap. I do not have a garage and I am coming up short with people who are willing to lend theres for a weekend or so. I'm in Jersey and willing to pay you for the space and your knowledge. Lmk
@@GaryLamb2020 I'm a married guy, so I can't roll to NJ to hang out and wrench on cars lol, but if you aren't able to do it yourself, I recommend finding a decent racing shop, as you can see it requires some very basic fabrication and shouldn't be very expensive.

What are you going to do with the bottom holes on the brackets where you installed onto the old quad shock holes? I'm considering doing the same to my notch...
the bottom of the bracket screws up thru the trunk like I showed, You can also cut thru the trunk floor and bolt them directly on the other side of the frame.
I absolutely LOVE the swap. The biggest difference i have noticed is the ride quality cruising is much better, the car is much more planted hitting bumps in the road, The suspension is also much more tunable, although i'm not really making continuous adjustments. I do frequently see people asking if IRS will make their car "better", but in my opinion it's really a matter of personal prefrence. Cobra IRS parts have become very expensive now, and there are a lot of solid axle upgrades out there that can make your car "better" as well, but for me, it's the IRS.
Great video, sir. I notice most people use the 03-04 IRS for the conversion. Is there something different about the mounting points on the 99-02 IRS that make them unsuitable for this conversion?
mine is actually the 99 IRS. They are mostly the same. People like the 03/04 because it came with stronger axles and had a diff brace. I have a steeda diff brace and the 03/04 diff and axles, so mine is basically the same as the newer one. swap wise it's exactly the same, and there are probably tons of people thinking they have 03/04 IRS but they are rocking a 99 just like me.
Premium Fuel Mag Thanks for the quick response. I've been looking online for an IRS setup. Haven't seen anything under $1000 yet. But I'll keep hunting. Happy Thanksgiving, and thanks again for the video and information.
expect to pay $1500 for a complete IRS, maybe even more if you try to piece one together. You've really gotta keep a sharp eye out for them if you want a decent deal. Once you get it, get a diff brace, and change all your bushings to poly. Don't mess with that over priced "Full Tilt" metal bushing kit, it doesn't get good reviews.
I appreciate people have hobbies and they cost money, and the sense of accomplishment and knowledge gain, but was it worth it versus just buying 2015 or later Mustang? $$$$$?
I would love to have an s550 Mustang, but these are 2 different beasts and there really isn't and to compare them would be apples to oranges. The S550 isn't "better" than my car, and by car isn't "better" than an s550. What i can say is that if i swapped my car for an s550, i wouldn't be able to thrash it like I do this car, i've also been able ot customize this car every way i can afford and i'm super happy with it, lastly, i wouldn't trade my experience building this car for anything. I've learned so much, so to answer your question, no it wouldn't be "worth it" to have just bought an s550, that wouldn't have met my goals.
IRS stuff is skyrocketing in price, if you can get a complete one for under $1000, you're doing really good. $1500, is about average, but, people are starting to get unreasonable in what they are asking for these.
4:46 this is NOT how you should run the bolts. The correct way is to cut holes in the trunk pan and put nuts on the inside of the frame rails. This is a great way to collapse the frame rails and not to mention that trunk pan metal is maybe 1/8 of an inch thick. Even using those large washers to spread the load isn't enough. I guess its a good thing you welded the bracket itself to the frame rail but people only using bolts should really do more research on this.
The frame rails won't collapse, it will just tear thru the thin trunk pan. If I hadn't welded everything down, i'd make a much larger reinforcement, but what I have has held up great.
@@Chad-Dion IRS costs 500-1000 bucks, I think. I biught mine a long time ago. I love it. Car handles great, rides great, exhaust looks amazing. I have no regrets.
5 lug rear drum conversion? What a waste of time. It probably would have been the same effort for that person to do a disc conversion. Yes, you'll need the new 5 lug axles.
That's not true I have a 87 coupe 4cyl it doesn't have quad shocks but it does have the mounting holes for the brackets it's on aod trans it has the hole for a clutch cable on the firewall with a solid rubber grommet plugging the hole! I going to doing a V8 swap I checked for the quad shock mounts I don't have the luxury of a garage right now going to have to rent a lil 1 just to get the motor in it! I can do it on the street but I live in Baltimore, MD weather blows right now well it always blows to cold or to hot!! Lol but good video I thought you had to buy them brackets that's good to know if I ever get a IRS get the rear mounts!
right, not all cars came equipped with quad shocks, but those brackets are really the key to the whole swap. I believe that modifying them the way I did is the most efficient way of getting it done. there are some other crazy things I've seen shops do, but that mess is in called for.
I was told that it was a 2001 IRS, but i later discovered had a 31spline diff and axles which is from 03/04 so i'm not sure if it was upgraded or if they seller just didn't know what year, There's also 1 additional difference on the 03/04 model which i dont fully remember at the moment.
@@Sgt.Slides What axles did you go with I agree first I blew an axle now I blew the irs diff.. but I have a 28 spline I’m looking for a 31 at the moment.. what axles did you get
The cost of 99-04 Cobra IRS components has become prohibitive. As an alternative, RideTech is about to release an IRS that will use plentiful and inexpensive S550 components. It should be on the market sometime in early 2024.
unfortunate how things have changed. This whole build started because I wanted to slap an IRS into a fox. Since then i have talked a lot of people out of doing the conversion because the cost just isnt worth it. I saw the new IRS system that came out. I think it's super cool, but i have mixed feelings on it, i think i'm just stusk in the mindset that frankenstiening cars together should be cheap and fads shouldn't make thingd unaffordable.
It's funny how foxbody guys swap in terminator IRS, and the termi guys go solid axle. Hahaha whatever floats your boat, but it's pretty cool that it's that easy tho...
yeah, the first time I met a guy that swapped a solid axle into a Terminator, I was like "WTF is your problem bro!" but they do it for drag racing, so that's understandable. Honestly, I don't think the IRS conversion is very popular, and there are cheaper alternatives to get your fox to handle better. I think folks go the IRS route just for the sake of taking the road less traveled, and because they have no interest in drag racing.
Premium Fuel Mag Yeah, alot of people find things to hate on or pick apart with some of my projects too but as long as it makes your car more enjoyable for you that's what the hobby is all about. Thanks for the vid, learned something new. Subbed.
Any one thinking about doing this, DO NOT WELD THE BRACKETS TO THE CAR. There is no need to, and if you every decide to sell the IRS you will have a harder time because those brackets are hard to buy separate from a complete IRS. I'd have to say overall this looks like a sloppy install.
I never intend to remove the brackets, and I can't see why anyone would buy a rare IRS fox and convert it back to SRA. That makes no sense at all. Welding the brackets in gives them much better attachment without having to cut and weld and modify the frame which is a VERY tedious install, and would add a days worth of labor to your conversion. Not sure what else was sloppy about the install, it only bolts up one way. Ease up keyboard warrior.
I like having the option to remove the brackets. Modifying the brackets to bolt in with the stock quad shock bolts and welding in plates in the trunk floor to strengthen for the vertical bolts took maybe two hours. It's far from tedious. As far as it being sloppy, I saw a few things that could be done much better. And it took me about an hour to remove the brackets for the SRA bump stops, instead of just smashing them away with a hammer like on your car. The rear brake hoses should be held in place with brackets, not zip ties. The stack of washers boogered to the hatch floor is not enough support for those bolts to get tight enough to do anything. I'm not trying to be a keyboard warrior, I'm trying to help other build better cars. One last thing, do you have spacers welded to the bottom of the springs?
Yes, there is also the route of modifying the bracket to meet the bolt hole as well. I detailed that in my write up on the website. It's a good alternative if you want to DIY this job but don't have access to a good welder in your workshop, and that would not require cutting and welding of the frame rail. Either way, my brackets are in, and I can say without a shadow of a doubt, I will NEVER want to remove them. The washers welded to the floor is plenty of support for those bolts. In hind sight, I do wish I had cut out a thick piece of plate steel and welded that in vs what I did, but I didn't have good drill bits at the time to really drill thru thick metal. I wish I could re do it, but there's no point, what's in there is perfectly fine. the car has been thrashed every kind of way since then and nothing has moved or flexed, it's solid. Zip ties are securing the brake hoses because it's impossible to get the OEM plastic clips from ford that do the exact same thing, calling someone out for zip ties? C'mon bro. The old bump stop location was actually mashed up when I crashed, witch is why I ended up tearing the whole car down and re building it over 2 months. Aside from a few ugly welds this IRS install is as solid as it can be, and yeah, lol, you caught me on the spring spacer. I welded an extra coil to the bottom of the spring to raise the rear an inch. A bit haggered if I do say so myself, but it works for now until I swap it for an adjustable coil over set up.
Hey PFM, I'm looking to add an irs to my foxbody. I have a question about the spring spacers: if you did that to rise the height by an inch, do u think it would better to just use the factory IRS springs? I'm not here to knock on you about the spacers, I just thought that maybe the stock IRS springs might be a better solution. Let me know, so I can order some. Thanks!
Premium Fuel Mag i actually got a 92 coupe with complete 03 IRS. I got it from am older lady who really didn't know much. I hated it. Wheel hopped all over the place with the slightest hit of gas.. it was just nasty. Went back to a solid rear and way better imo

I'm not trying to be a keyboard warrior, I'm trying to help other build better cars. One last thing, do you have spacers welded to the bottom of the springs?
Yes, there is also the route of modifying the bracket to meet the bolt hole as well. I detailed that in my write up on the website. It's a good alternative if you want to DIY this job but don't have access to a good welder in your workshop, and that would not require cutting and welding of the frame rail. Either way, my brackets are in, and I can say without a shadow of a doubt, I will NEVER want to remove them. The washers welded to the floor is plenty of support for those bolts. In hind sight, I do wish I had cut out a thick piece of plate steel and welded that in vs what I did, but I didn't have good drill bits at the time to really drill thru thick metal. I wish I could re do it, but there's no point, what's in there is perfectly fine. the car has been thrashed every kind of way since then and nothing has moved or flexed, it's solid. Zip ties are securing the brake hoses because it's impossible to get the OEM plastic clips from ford that do the exact same thing, calling someone out for zip ties? C'mon bro. The old bump stop location was actually mashed up when I crashed, witch is why I ended up tearing the whole car down and re building it over 2 months. Aside from a few ugly welds this IRS install is as solid as it can be, and yeah, lol, you caught me on the spring spacer. I welded an extra coil to the bottom of the spring to raise the rear an inch. A bit haggered if I do say so myself, but it works for now until I swap it for an adjustable coil over set up.
Hey PFM, I'm looking to add an irs to my foxbody. I have a question about the spring spacers: if you did that to rise the height by an inch, do u think it would better to just use the factory IRS springs? I'm not here to knock on you about the spacers, I just thought that maybe the stock IRS springs might be a better solution. Let me know, so I can order some. Thanks!
Premium Fuel Mag i actually got a 92 coupe with complete 03 IRS. I got it from am older lady who really didn't know much. I hated it. Wheel hopped all over the place with the slightest hit of gas.. it was just nasty. Went back to a solid rear and way better imo
Much bla bla bla
yeah, that's kind of the point.
