Well, you do sell IRS components so I would expect that to be your recommendation.
Personally, I would ditch the IRS immediately. I did after breaking the IRS and I'm pleased with the solid axle.

Congratulation's!! You have a Mach1 with a Supercharger:banana:

Yeah...because a IRS and SRA are the only differences between the two. Some of you guys make me shake my head. You guys aren't really like this in real life are you?

For years great handling cars have been coming from the factory with a SRA. I don't think the IRS is bad (I still have mine) but I don't think a SRA is bad either. I think you all need to just bolt your penis's back on and quit crying like a vagina about your ride comfort. Like said above, it's a Mustang for ****'s sake.

What's wrong with a SRA on the street? Tons of cars use a SRA just fine.

Everytime I see your sig pic with wheel combo and color cobra gets me all tingly inside...looks very good.

Op a friend of mine has 800rwhp on his irs with no issues. He has the mm bushing kit,i do hear the ftbr kit is better though.

True............ But If someone wanted a straight line fast car they should have gotten a Mach or GT. The Cobra with a IRS was built (but sucks in stock form) for handling the road. The IRS has proven its self in the 1/4 mile time after time though. just not ideal in stock form
But thats just my opinion:)

One of the reasons I sold my cobra..there were a few others though.

Then there must be a reason why so many cars come with an SRA from the factory.......

I drove my first Cobra 99.99% of the time on the street(1 track day with 5 passes) and I liked the SRA better then the IRS, ON THE STREET..

Why don't you post this in the Cobra R section?

And that's fine, but I still disagree with the "if you want a fast straight line car just get a GT or Mach" because then you're still 10 steps behind with a junk non forged bottom end, weak trans that can't handle over 400rwhp, etc. If I were looking to build a dedicated drag car (which I'm not, I just enjoy a few passes down the track here and there, drive it on the street 90% of the time) and was stuck on a 99-04 body style I'd still go with a 03/04 Cobra. I'd rather buy that and only have to swap the rear end for a SRA, than buy a GT/Mach and have to build a forged shortblock, do some sort of power adder so it's actually not a turd, build a trans that can handle at least 400-500rwhp, etc.

99.9% street car here with a solid axle and its just fine. It's a mustang. Buy a BMW if you want comfort. There are zero creature comforts in a cobra, the interior sucks, seats suck, etc...and you're worried about ride quality? Odd.

Some people have differeing opinions about ride and handling and what the definition of 'fast' is. There are people that think a stock Mustang GT (pick any year before '05) handles well and has good brakes. Let's just say, you probably don't want to listen to their advice about how to set up your car when they offer their opinion on the interent.

You are correct, many vehicles use an SRA today. These vehicles include city buses, dump trucks, garbage trucks, fire trucks, UPS and Fed-Ex delivery vans, etc. On the other hand, every single high performance sports car that is manufactured today comes from the factory with an IRS under it. :read: Do you have any idea why that might be? :idea: Can you name me one single high performance sports car that comes from the factory with an SRA under it? Just one!! Start Googling, I've got all day! ;-)

Bruce,

It's obvious some of these people haven't driven a IRS with your bushings installed. I just installed your complete kit and wow! Reminds me of my old Supra! The difference is amazing. PVH increase is minimal. I only have a minor gear noise on slight decceleration and acceleration at around 50mph. That's it!

Btw I'll be in touch soon to get your bumpsteer tie rods.

A Mustang is NOT a sports car! :read: It's a pony car with a back seat.

Besides, the S-197 is NOT a quadra-bind, four link rear suspension like the SN-95 cars. It's a three link with a panhard bar. There is a HUGE difference. :idea: In addition the S197 chassis and suspension is so far superior in design as compared to the SN-95 cars, it's like comparing apples to hollow point bullets. ;-)

Ac your opinions and statements are so biased that it appears to me that your only trying to sell a kit. Maybe this should move to the market sectioned based solely upon your "biased" posts. Ditch the Irs idea and go sra. Heck go 9inch and don't look at back. Irs is not for track and I highly doubt he is going to go corner chasing in his 900hp fox. He is going to go in a straight line whether Irs or sra. No corner carving for him.

Sports car or not.. good chassis or wet noodles with that car ford still proved you can make a solid axle handle.

And this is coming from a firm believer in the irs.. with a completely built rear suspension including your kit. 485rwhp breaking halfshafts hopping all the way to the bank... 9in and call it a day, end thread.

I had just about every mod possible done to my IRS and it 60' like doodie. Switched to a solid axle and dropped 2 tenths off the 60' by launching the exact same way. Best of 1.68 down to a 1.47.

Honestly as far as driving around town I don't know if I could tell a difference at all between the two rearends.

I know going from my Mach 1 to my Cobra, I can't tell a difference around town or highway expect the glorious "clunk".
