Re: How-to install SN95 IRS on FOX Reply #3 – December 09, 2004, 04:33:07 PM Half shaft to break- Is that a common problem? He said it is for use on the street, drag racing, and in open track road race events. It should be strong enough.... wheel hop out the yin-yang...- huh? what do you mean? more bushings to squeak- Why it should Squeak? do you think its gonna sqeak so much that it would be anoying?Im not arging with you, I'm just curious....

Re: How-to install SN95 IRS on FOX Reply #4 – December 09, 2004, 04:51:02 PM I'm not sure what you're trying to achieve by swapping in the SN95 IRS. Here is an excellent thread describing the pros and cons. Keep in mind this site is very much inclined towards cornering, not drag racing. Both of the people that performed the conversion you linked to partite in this thread. Quote Selected

Re: How-to install SN95 IRS on FOX Reply #6 – December 09, 2004, 05:15:16 PM Much, much more IRS information is available by searching Corner Carvers. They have by far the best archive of technical suspension discussions about Mustangs (and by corollary Fox T-birds and Cougars) on the 'net. Quote Selected
Re: How-to install SN95 IRS on FOX Reply #7 – December 10, 2004, 08:36:00 AM The Cobra IRS is heavy and unimpressive. Yeah compared to a stock stick axle the ride and cornering capabilities are improved, but so much needs to be done to bring them up to an acceptable level when they are to be pushed hard.They are an extreme compromise in that they had to make them fit under the contraints that they could put either into a chassis on the assembly line without any modifications to the chassis...just bolt it in. They are full of soft rubber bushings, and they have to be so heavy because of where they have to put the spring and the correspondingly high spring rates they need to run to get decent wheel rates. The rates get increased even more for performance useage.I just am not impressed with them at all for anything other than a gee whiz item...esp in their stock form.That's why I'm working on my own with a buddy.
