    I have yet to actually drive a Cobra or any mustang with a IRS. Mine is a DD that I want to make a little more nimble in general. I have no "goal" for the car ie. drag car or track car. I'm doing mods that actually work. I put on rear LCA's with a spherical end, I have 4.10's awaiting install. Aluminum DS will be next followed by FLSFC's then prob stop.

    I'm glad I didn't go IRS with all the money it would take to beef it up. I'm stock power wise too. I have asked people from amature auto-x guys all the way to championship holding roadracers...and they all say to stick with SRA.

    "All the fastest cars in the American Iron are a SRA car."-Paul from Paul's Automotive here in Cincinnati.

    From what I have read/heard, that by the time you mod the hell out of the IRS to be a GOOD rear, you have taken the IRS out of the IRS...stiffer springs etc.

    I've been wanting to drive a car with PHB/TA and see how comfort is. No I don't want a Lexus but I do want a agile "muscle car". If I can do all those mods and it rides relatively like stock...I'm happy. I also realize that you have to give a little to get a little. Give up some quietness and gain some NVH.

    I wish the links to your photos worked....

    I'm getting a list of parts together to start a swap in January and I need a couple of good benchmarks.

    SRA make great boat anchors, the way the flanges for the ends are made, they hook the bottom real well and prevent drift.
    The IRS is the only way to go for corner carving, true the SRA can be made better but never as good as the IRS. If you want to go drag racing then definitely go with the SRA. I have a 99 edge, 93 FOX and a 99 cobra all have the IRS in them, all get autocrossed or HPDE driven.

    IRS being better than an SRA? No doubt that it's a smoother ride. But better for performance upgrade as a necessity? Nope. Since I hillclimb the car and that is the most extreme driving on the street you can do, I have yet to find a reason to move from SRA to IRS. I just don't feel that the corner carving ability of the IRS will out do the SRA. Stock for stock, yes. Built, no.

    I IRS swapped my GT and about to do the same in my Mach 1. You will thank your self. My Gt has a better 6o on street tires then the Mach 1 on drag radials. That being said the Gt is not stock and the Mach is

    So from reading this I'm still lost a little, since most of your are writing opinions vs facts, after 2 pages of reading i skipped to end to comment so excuse me if I miss some good hard facts. My plan is to twin turbo my cobra, so I would NEED SRA over IRS correct?? That's what I am getting from this, I'm looking to make 900-1000 with this car all said in done. Can I build the IRS already on it, or should I start looking to SRA swap.
