IRS cradle: How to tell if it's "squared" or properly aligned?

I'll be (attempting) my CB005 installation this weekend. Hoping that the cradle is properly aligned from the factory....

How did you make out with the installation?

Yep, got it done in a couple hours. My cradle was off slightly from the factory and so I had to loosen all four bolts in order to install the BMR Lockout kit.

The kit essentially centers the cradle. I had to get creative with pry bars but I did get it.

I just installed my CB005 this morning. Installation went great, but the steering wheel is off ever so slightly now. Just picked up the car yesterday and felt the wheel hop on the way home. After the Lock-out kit installation, non was present after several acceleration tests.

Kelly do the camaro and challenger irs's have these alignment issues or is this just a Ford thing?

I know the Corvette has alignment dowels built into the chassis that keeps this from happening.

Thanks, i also know the corvettes's suspension is alot more critical to get right because of the type of car it is, but still good to know.

We will have a kit available late next week to work with CB005 customers.

Talking to the Steeda Techs it takes only about 30 mins to install our Steeda IRS alignment kit. as mentioned in this thread it definitely locks the IRS sub frame in place once and for all.

Any update on this?

Great thread, I did BMR lca's & panhard on my 2014 Cyclone for this issue. My 2016 GT needs attention as the rear want's to go right on launch. Another friend of mine with a Shelby 2009 stated Ford was banned from the 1/4 mile tracks at one point in history for mishandling so badly. So this has been a problem for a while with Mustangs. I'll do the cb005 and when I can afford it the rest of the Party! Dang Ford, I am ashamed for you!!

Just curious -

Has the kit been released by Steeda to work with the BMR CB005?

Other questions:
If the IRS cradle is ever so slightly skewed, will this affect the driveline, such as possibly cause the ever so common (and unresolved) "driveline vibe"?

Can the cradle be improved upon, rather than "bracing" it? Such as a possible aftermarket replacement of the stock cradle with a better cradle?

Thank you,

Is there a chance that someone will design an aftermarket cradle that is better than the factory Ford unit?

For handling? No. For drag racing weight reduction yes. Watson
