the owner of the shop thats doing my cobra swap has offered to trade his built IRS (with bushings, irs brace, level 5 axles, etc..) for my SRA (with uca and lca and 3.73 gears). but id have to offer a few extra bucks to go along with it. he told me to get online and see how much i should offer b/c he dosnt know what to ask for along with my SRA. what should i offer?
As long as your running street tires, you should be ok although anything can happen. There are different companies (Steeda, Max.Motorsports ect.) that have a upgrade package for the rear. I changed the bushings, added a brace and so on.
I say good trade.. I'm running around 850 rwhp and never had a prob. They handle a whole lot better on road which from what u say would benifet u more. The only draw back is the IRS is fragile to wheel hop. As long as u use slicks on the track and keep the spin to a minnamal,,you will be aight. If he is wanting ur setup do a even swap for your hospitality in helping him... ?
hey cobrals1eater,did the bushings and brace help you with the hop ?forget that irs. my 03 cobra is my first irs and i dont like it at all .im puttin down 483 horse,and cant even power shift from 1st to 2nd without the rear end feeling like its gonna rip out of the car..8.8 straight axle here i come.
yeah im putting down about 530 to the ground. plus, a solid rear weighs alot less than a irs. about 150 pound difference i think.
I read an article that said it only weighed 80lbs more, hmmm. I added aluminum diff, bushings and I get a little more vibration but oh boy did it make a difference in response and wheel hop.

When you say a little more vibration, is it really noticeable or no big deal? I'm considering going through and replacing all the bushings,etc. but I'm curious about any change in ride quality(stiffer/harsher, noisier). Appreciate any input you have, thanks.

I don't notice it at all unless I'm at higher rpm and off the throttle, But when on the throttle and normal driving it's not bad at all.
