Cobra's run good if you can get the weight out of them!

Bruce954 · 02-18-2009, 02:40 PM

The Cobra IRS is not as weak as people say, just avoid the wheel hop and you can run a lot of power through them.

The cobra IRS is a huge POS it was an after thought by ford and they made it work... just not well

Blownsvt · 02-18-2009, 02:54 PM

The cobra IRS is junk compared to other pieces. The half shafts are weak. and the diff cover likes to break. I broke a dif cover on mine 1 time.

I think an abundance of Cobra owners running 600+ through them would disagree.

Most drivetrain components tend to show there weak sides when you push as much power as you do through them.

I had a built IRS with 618whp in my 04 cobra, I ran that car hard launched it hard all the time never any problems, my 03 cobra that was bolt ons 480whp was a STOCK IRS with just a brace never any problems ran at the track, street raced from a dead stop all the time never any problems...

i see. i have heard that to go to all the good stuff to make them better it costs alot. way more than the cost to swap to an 8.8 SRA.

Just half shaft and brace, Pretty stock for bolt ons

When I broke mine (once) was cuz the bearings on the half shafts failed and caused the center secition to get binded up and broke the main cap of the center section.

Level 5 half shafts $1579.99

2000AZ4.88GT · 02-19-2009, 01:58 AM

I'm running an IRS from a 2001 cobra, and I've probably only spent 2k in "building it up"

the cars are faster with the soild. Plus less chance of breaking shit, But since my car does not go to the track but maybe once a year IRS is better on the street IMO so that is what I have, IF I draged the car more it wouild be soild for sure

I don't know about that man. With an IRS you can adjust the suspension far more than with the straight axle.

Like I said, I can put a ton of camber on my IRS, can't do that with a solid axle

I've been told that the 1.7 60' I pulled was pretty damn good for street tires, doubt I could have done that without my suspension, but who knows.

I'll take an IRS no matter what. Then again, I actually enjoy taking curves confidently

edit: I rescect anyone who can build a 10sec street car or 11 sec for that matter. I know what it takes and costs to build one of that magnitude.

since most road course guys run setup live axles.... man i bet those guys are idiots

I've never met a road course guy in a mustang or otherwise that could keep up with me with a straight axle. Not to sound cockey, but Ive just never seen it.

I've fallen out of the race seen since this last winter, but before that, 11k out of the 20k miles that I've put on my car were RACING. If there was someone out there with THAT badass of a setup, I'm sure I would have been beaten far more than I have.

As of yet, the only person/car that has beaten me was a bone stock C6 Z06, with an absolutely amazing driver. I'm a good driver and all, but this guy could have taken my car and run at least half a second faster than I was running, without pushing the car very hard.

Most people use solid axles because they are far too cheap to actually want to brace the IRS.

If your talking about S197's, I don't think anyones figured out how to retrofit a Independant rear, so just factoring them in is going to hurt the average ammount of IRS equipped stangs. Not to mention, they have pretty sophisticated pieces, IE the steeda watts link, where if someone in a new edge wanted that, they'd have to learn how to fabricate

IMO the IRS placed in 2001-2004 Cobra's was an after thought, and under engineered.. i really think they are a total POS

BTW i spent the money on one, Level 5 axles, bracing, etc....

Clint likes his IRS, more power to him, lots of ppl have had great luck with them but i did not. and will most likely NEVER have anything good to say about the stang IRS again

But keep in mind im a strait line guy, if im turning ill get on my GSXR

saleensonoma · 02-21-2009, 07:44 PM

as for mustang guy i love maximum motorsports pieces and make great suspension packages for irs or straight and they r amazin. Expensive though

The ONLY reason anyone who races road courses would either keep a straight axle, or swap to one, is because A. either the rules prohibit it (IE they're racing in a stock, or street prepared class), or B. they are swapping to a Ford 9".

The 9" is great because it's easier than shit to change the centersections out, depending on the course, you could have the perfect rear gear.

when it actually comes to running, the IRS is FAR superior to any straight axle.

You must have bought some cheep stuff if you broke the IRS, The steeda piece alone will keep the Diff from coming out backwards. It doesn't take much, Level 5 axles I would consider an afterthought, IE, you have to do the same thing on a straight axle car, you don't see anyone with a High HP stang running 29 spline axles
