To IRS or Not to IRS

Okay so I know others have discussed it in the past in a power setting, and such.

So i've heard about the problems were people in cobras are snapping there IRS trying to drag them with over 500hp.

But what about IRS on a Mach 1 used for autocross, cornering handling, etc. Give me your input, what u recommend, past mistakes, horror stories, etc.

Re: To IRS or Not to IRS

Depends what you want to do with the car, if ya want to drag it then get the solid axle. If ya want to autocross it or a comfy riding dd, do IRS

Re: To IRS or Not to IRS

In my opinion, the IRS will be better for you. You could set up your SRA to work just as well as the IRS, but you will need to do a lot of research into what parts you need to make it happen.

Give Maximum Motorsports a call and see what they recommend. I have a feeling you can build an extremely nice SRA setup for less than the IRS swap.

IRS is mainly good for cornering, plus I like the way the exhaust looks from the back, I know that's not important thats one thing that I like on the cobras with the exhaust under it. But for pure drag racing, the best thing is to have solid rear end. Specially with a car that has alot of power..

Even better than how it looks, removing and re-installing is a ton easier since you don't have to go up over the axel anymore. lol

Re: To IRS or Not to IRS

I'm a purist...otherwise my car would have a solid in it right now.

The IRS is not a bad platform, but honestly, a solid can be built to handle and perform better for cheaper. It will cost you a minimum of $1500 to properly build an IRS. You can build one heck of a solid for $1500, not to mention the cost of an IRS.

Look into the 3-link setups for new edge cars.

Re: To IRS or Not to IRS

I dig the IRS and it handles and rides very nicely. Some good advice above, you have things to think about =)

Re: To IRS or Not to IRS

the SRA can be made to do amazing things, but at the cost of money and ride quality.

The IRS also is not cheap to beef up and make handle good but it can be done. Google fulltiltboogy and also maximum motorsports. That together can get you doing some great stuff. The IRS gets a bad name due to the crappy bushings and the design overall is lacking a bit.... it can be made into a great item though and the ride quality is great with it.
