smallblocksn95 Posted February 7, 2015 Report Share Posted February 7, 2015 I have the opportunity to get in irs out of an 03 cobra and I'm on the fence about it. I planned on doing the full tilt kit before I put it in if I get it. The car sees the track 5 or less times a year. What do you all think? Link to comment Share on other sites More sharing options...
SublimeRT Posted February 7, 2015 Report Share Posted February 7, 2015 What about it has you on the fence? I think the IRS is really nice. Rides and drives pretty well, looks cool, and it's unique. It should handle a couple trips to the drag strip just fine with the right setup. A couple guys on here have the IRS with the FTBR setup and should be able to give you some more insight on it. The FTBR kit is real good stuff though. Link to comment Share on other sites More sharing options...
Det_Riot Posted February 7, 2015 Report Share Posted February 7, 2015 Hey @V3NMUS how well is your IRS holding up at the track? Link to comment Share on other sites More sharing options...
95riosnake Posted February 7, 2015 Report Share Posted February 7, 2015 If you're doing the FTBR stuff, the track is a non-issue. I've done the swap and would do it 100 more times. I haven't missed my SRA one bit and would never consider going back. Link to comment Share on other sites More sharing options...

smallblocksn95 Posted February 8, 2015 Author Report Share Posted February 8, 2015 For those that have done the swap, what cat back did you go with? I love my magnapack that's on the car now, but they don't offer it for irs. Is there a crazy difference in sound between the standard magna flow mufflers? I was kinda looking at the pypes set up, but have never heard it in person Link to comment Share on other sites More sharing options...
Zach Posted February 8, 2015 Report Share Posted February 8, 2015 The standard are a bit quieter but the same tone, that's a comparison with mine and my buddy's car. I have the lager mufflers and he has the magna packsSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Cobraracer46 Posted February 8, 2015 Report Share Posted February 8, 2015 The IRS will definatly improve the handling and ride. You can check out my IRS upgrade thread here http://www.sn95source.com/topic/5091-how-to-upgrade-the-mustang-cobra-irs-for-better-performance/ were I upraded the IRS with polyurethane bushings and other parts.

95riosnake Posted February 10, 2015 Report Share Posted February 10, 2015 I think that would be more work than it's worth honestly lol. You'd probably be talking a level of modification on par with back halfing the car. I guess if you came into the S550 unit dirt cheap it would be worth all the work, provided it didn't need overhauled like the 99-04 version did in terms of bushings and such.

SublimeRT Posted February 10, 2015 Report Share Posted February 10, 2015 Haha, yeah probably more work than it's worth. I'm just stirring the pot a little. Was a passing thought when I first saw the S550 IRS is a removable assembly like the Cobra IRS. I bet someone will do it sometime, but not me.

RedTwilight Posted February 11, 2015 Report Share Posted February 11, 2015 I've had my '03 IRS for at least 5 years now. Still hadn't installed it in the car! I want to do the FTBR kit before it goes in but hadn't had the money to get it all and the diff cover yet. But someday... someday... I WILL get it in!

Sleeperstang1994 Posted February 13, 2015 Report Share Posted February 13, 2015 I think I have had mine for 5 years. I did the full FTBR kit. I can't comment on how it handles because it has never moved. However the quality on their parts is too notch. And customer service is amazing. Can't say enough good things about them.

derry96gt Posted March 17, 2015 Report Share Posted March 17, 2015 Im currently finishing up my irs under my 96gt did the updated bushings from maximum motorsports and front diff brace and rear diffcover brace. does anyone know if you can use stock driveshaft ive heard it will fit and some say no Link to comment Share on other sites More sharing options...

95riosnake Posted March 17, 2015 Report Share Posted March 17, 2015 I used a Ford Racing aluminum driveshaft, but it's essentially a stock 94-95 driveshaft length-wise. However, I'm using a Tremec 3550 so I don't know if that changes anything for the driveshaft length. Link to comment Share on other sites More sharing options...
RedTwilight Posted March 17, 2015 Report Share Posted March 17, 2015 What year model is the IRS from? I know if it was a 03-04 you would have to use your factory pinion flange or use a hybrid U-joint to adapt to the '03-04's pinion flange. I'm not sure right at the moment about the flange from previous year model IRS. Link to comment Share on other sites More sharing options...
smallblocksn95 Posted March 18, 2015 Author Report Share Posted March 18, 2015 03-04 s had a larger pinion flange because they used a larger u joint. All other 8.8s solid or irs, had the same flange (79-04 mustangs) Link to comment Share on other sites More sharing options...

95riosnake Posted March 18, 2015 Report Share Posted March 18, 2015 I used an 03-04 pinion flange and a hybrid u joint. This is exactly what I did as well. I think I remember @derry96gt saying he was putting either a 99 or 01 IRS in, so that might not even be an issue. Link to comment Share on other sites More sharing options...

javorm1 Posted June 24, 2017 Report Share Posted June 24, 2017 I know this thread is a couple years old. But I was wondering if anyone has gone from a full touque arm / panhard bar setup to an IRS setup. If so, did you like it better? Ive been wanting to put an IRS in my car, but have invested quite a bit in the current setup. Link to comment Share on other sites More sharing options...
Magic Posted June 26, 2017 Report Share Posted June 26, 2017 My old SN95 car I did the Griggs GR40 Super Street setup (with a few upgrades to the kit). Awesome night and day setup over a modified 4 link (I had the Eibach Pro Street system and swaybars before the Griggs setup). When I built my Cobra, I decided not to swap the rear GR40 stuff over and go IRS instead. I did the Full Tilt Boogie FT5000 kit and a FRPP Diff cover. Im on single adjustable Koni's and coilovers all around. All I have to say is, I love it! I'd never want or put back a solid axle even if Im making a 1000+ HP.

javorm1 Posted June 26, 2017 Report Share Posted June 26, 2017 Sounds like the IRS is a pretty sweet install. I read the article and it seams to more predictable. I have to focus on getting my car back from paint. Hopefully within the next couple days. Now I wonder how much I could offset the cost of an IRS with selling my setup. It never ends.

Supporting Member seijirou Posted June 26, 2017 Supporting Member Report Share Posted June 26, 2017 Another IRS swapped sn95 over here. I've had mine since 2004 though, and I've swapped it from car to car more times than I care to recount but perhaps that's some indication of how much I like it. I have the maximum motorsports package on mine and with the proper front suspension it makes a mustang feel like a go-kart. Link to comment Share on other sites More sharing options...
javorm1 Posted June 26, 2017 Report Share Posted June 26, 2017 I've been watching them on ebay for quite awhile and they do very in price. I seen one asking $2900, but that looked to be fully built. Link to comment Share on other sites More sharing options...
Moderators Psychorugby Posted June 26, 2017 Moderators Report Share Posted June 26, 2017 2 hours ago, Evilcw311 said: I'd say you should be able to offset a decent amount. A year or so ago you could still find 03/04 irs complete for around $600-800. Now that's about what the 99-01's go for and 03/04 for for over $1k Higher than that now. Most are around $1000-1500.
