I have to disagree with you on this. My car rides so much better/smoother than when it had the irs. I have stock gt springs and shocks. You make it sound like the sra is for drag cars only. If it was so bad then 90 something percent of the cars out there would not have it. V6, gt, mach 1s all have them. I used to have a vette with the z51 suspension and the cobra rides almost as bad as it does with irs IMO. I guess its all personal preference.:rockon::beer:
Who has done solid axle swap? how do you like it?

................but chances are 99.9% of the miles you put on the car will be on the street where an IRS has quite a few advantages over a stick axle. Something tells me your car won't be built to rip a 9 second 1/4. Ford did not go thru all the trouble and expense of equipping the Mustang with an IRS if it didn't have advantages.
This topic goes back and forth like a ping pong game :rollseyes Do a search and educate yourself before taking this step. There is quite a bit more to this story then you are being told on this thread.
x2.
STREET MANNERS and RIDE QUALITY are the same before/after. I have 20,xxx street miles with the IRS in my car and 10,xxx street miles with the SRA. The car rode stiff before, it rides stiff now. It's a Mustang, not a Cadillac. I don't know where all of these people are getting "The IRS rides lightyears better," because it doesn't. If you are building the car up for performance anyway, ride quality is truly a moot point. :bored:
One more question guys. What gears should I go with? I was thinking 3.73 but some people say to stick with the 3.55's
what are your thoughts?
as far as power I only have a 2.8 pulley and making 450 rwhp but by next year after the SA swap I plan on putting a 2.3 whipple in making about 570 rwhp, will 3.73's be too much?

Why don't you post this in the Cobra R section?.....better yet "Corner Carvers"!
op:
I love my solid axle, couldn't be happier man.
As far as this question. I have 3.73s and my Kenne Belle which is a nasty combo. I make right around 550 on my conservative 91 tune and with the 3.73s it pulls incredibly hard.
I think 3.73s are the perfect gear IMO. I had 4.10s in my GT and they were a little too much.

There isn't much difference between 3.73' and 3.55's. If you want to step up, go all out for 4.10's. I think you'll be disappointed spending the money for 3.73's and really having no difference.

..... because the question was asked in the forum of the car that I actually own? :bored:
Are you telling me the Cobra R and the Terminator don't have anything in common?
cool, I'll go 3.73 in that case. I had 410's on my 02 GT aswell and with the vortech blower I was running out of gear at the track
well the rear end Im buying is coming out of a 2000 GT so I believe it has either 3.27 gears or 3.08? so either way I have to change the gears, I just I fgure I might aswell go 3.73 while Im at it
No, I'm saying the question was asked int the Terminator forum, the only one I visit, so that's what I'm answering the question here, and not in the R forum.
You dont have to swap pinion flanges. Since you are swapping with a friend. Go to Napa get a Precision 448 U joint. What you need to do is swap the yoke from your DS to your buddies and vice versa. The precision u joint will let you do this w/o having to change the pinion flange. If you do change the pinion flange instead, make sure you check the turning TQ before you remove it and TQ it PROPERLY!
actually I ended up buying a solid axle from a friend and Im keeping my IRS although might end up selling the IRS after a while if Im satisfied with the solid axle
in that case I would be taking the pinion flange off my irs and putting it onto the SA
thanks for the info tho, I will keep it in mind incase
it has d stock belstein shocks... i guess i should check into GT shocks then :shrug:
No problem. Just make sure you do not gun the nut on for the flange. You need to TQ it properly. If you dont know how, what you need is a dial type tq wrench. Measure the turning TQ of the nut on the solid BEFORE you remove it. Its only going to be around 25 +/- a few, I forget the exact spec. When you tighten the nut with the new flange you need to TQ it to the same measurement as you took.
ok gotcha, I will make sure the shop that is doing my rear end does this
thanks again
If your looking to go ina state line than the solid is the way you want to go! The solid with a spool is very nice to drag racing a little pain inthe ass on the street. The reson why a lot of cobras go solid is because of the weight they take of (up to 100 lb) and the fact that it doesnt brake any more. Like a 600whp cobra can have a irs but a 800whp and up cobra cant. IRS= nice handling, good enough bite, nice ride.... solid= no handling, drag style bite, good ride, perfact drag car. You pick
That is so untrue. How can you say that a solid axle doesnt handle and is only for a drag car? That is the biggest misconception about solids ever. Then how come a solid came in 90% of mustangs since they were ever made?? This argument can go on and on forever. You can make both rears handle nicely without a doubt. How come MM builds their road race cars with solids?? I can go on and on about this, but to say a solid doesnt handle is absolutely rediculous.
Stock SRA vs a Stock IRS the IRS will handle and feel better hands down. But a few changes to the solid, shocks, springs and it handles just fine.
