Yeah but if he's not going to be drag racing every weekend who cares if its not super strong. If its going to be driven mostly on the street then why not do the swap? Superior ride quality and handling.
I pretty much never drag race so what possible reason would i have to keep the SRA. That could be the same for soldier.

But why drop 800$+ in an IRS for a car that you are using as your weekend toy? If it was free to do the swap? sure why not. Its more of a cost vs reward situation for me. The reward is not even close to worth the cost. And for it to be properly setup so you can do both? You are looking at around 1400$ or so.

That's almost like saying why spend $2000 for a supercharger. Its to make the car more fun to drive. I know i have way more fun driving my car with the IRS just because it handles so well. For people who drag race all the time then yeah its a dumb swap but for street/auto-x ill take an IRS any day.

Even if it takes $400 cash and your SRA for the swap, bushing kit is right around $650 and if you wait, you can usually find a sale around christmas time or tax return season you can find good deals too. And if you do the install yourself(plenty of online write-ups and directions and advice can be found on Fulltiltboogieracing.com...which is the only source I would buy the bushings from anyways) youre looking at just over a grand for a properly setup IRS. Throw a cover in there and youre looking at $1200. Build an SRA properly with 31 spline axles and differential($500ish for 03 cobra diff and moser 31's), new shocks($200 for a good set of shocks), upper and lower control arms(another $300 for UPR or something) or a torque arm and phb setup($978 from MM) and you have about the same or a lot more wrapped up in building your SRA than you would doing bushings and a cover on the IRS. Might be a little stronger, but to me I couldnt justify spending that kind of money on a suspension design that was also used since 1979 either...and rides like it too.

Both examples properly built, they might handle the same on smooth surfaces, but the second you throw in a bump or uneven surface, bye bye SRA. For launching, use of slicks reduces breakage over street tires or drag radials because sidewall helps absorb shock, allowing one to launch somewhat like an automatic that is a smooth engagement on the drivetrain.
For a street car, no other choice to me other than the IRS.

There really is very little to no cost difference. I got mine for a straight up trade. Only thing is, I had to drive a cuple hundred miles to pick it up. If youre into drag racing and drag race on a regular basis, then solid axle all the way, but if you want a nice smooth ride irs all the way.

The guy that tj posted about has a stock irs except for diff bushings and a brace iirc he told me one time but I have slept since then. So it doesn't take a lot of money to make it handle high rpm launches. Just dome bias ply tires. I my self will never get rid of my irs for an 8.8 sraand I do mostly street racing and drag racing.
