ive noticed that the prices of these are up there so i was wondering what are the width dimentions in the front and back of the actual subrame? ik they fit the foxes but i was gonna look else where for an irs that could reep the same benifits since i wanna drift my car and live axles suck for drifting. and that i cant afford a $1200 rear axle thanks.

If you know that they fit the foxes, just measure where they would mount and you have the demensions. IMO you don't need an IRS to drift.

I'm not a drifting guru but from what I understand about it is that it's all setup in the suspension (even with a solid axle). I'm thinking even the pros out there are running solid axles in their drift cars.

I'm pretty sure the drift champion Vaughn Gittin has a solid rear axle in his Mustang. Of course that is based on a different rear suspension geometry from the '05+ mustang. But you can upgrade and get most of the posative qualities of the '05+ rear suspension by installing a steeda "5-link" rear suspension the foxbody.

The IRS will fit in the fox but I believe there is a little "massaging" that needs to be done where some of the subframe mounting buchings are just a little bit wider.

Yea Ik that Jr is using a live axle and that does work for the 05 and ups and Ik the cobra its does fit I just don't have 1200 to spend on a rear axle when I cab spebd a quarter of that are put one from a Toyota or Nissan in. I was just asking for measuments so I can figure out what rear subframe will be close

That is a common misconception about live axles. Vaughn Gittin has a live axle LOL. So do the other guys drifting Mustangs. A properly setup live axle with a panhard is fine. Look at some of the griggs and maximum motorsports stuff...

My friend is a Canadian Pro Drifter and there are a lot of great cars that have a solid axle. All the old AE86 are solid along with many other cars. You don't have the toe adjustments and stuff with a live axle but less to go wrong. Totally up to you. The Cobra rear is around 1.5" wider I think.
