My IRS swapped sn95

all i have to say is i put a cobra IRS in my 85 fox body and drilling all the 1/2 inch holes was the biggest pain in the ass. considering you have to drop the gas tank to do that. other than that it should be straight forward. and also you have to remove all the bump stops and brackets, including the outer ones that are spot welded to the frame rails.
Alright, I finished technically speaking... Everything went together and fitted up great. Got the wheels on and drove it out of the garage. flows sound great, not too loud at idle but loud when you get on it. I drove it down the road and everything was great, no odd sounds, clunks, or the car pulling (even without a alignment). After a mile or so I felt it necessary to do a little slalom to see how it felt... It was awesome, car was a rock even with the sumi's! Of course right as I was pulling into the driveway I heard a odd noise... I removed the wheels again and noticed while i was removing them that the hub was moving alot... great more work.
Finished... kind of:
hub that has some play:

So I think that that wheel nut is just loose but worst case its a wheel bearing.
Im getting the registration taken care of next weekend.

its been installed for a while now. love it! handles like a monster, only hops when the tires are cold (like mornings). even then its pretty minor, during the after noon Id be surprised if anyone could tell there is any hop!
Differential whines a little but only under deceleration but for solid mounts its fine. As for weight I haven't weighed the car before but I've heard any where from 70-125lb weight gain. However there is about a 75lb unsprung weight loss doing the swap (faster wheel reaction think of the car flipped upside down and the car moving the wheel upward. With the big old SRA it reacts slower...)
Haven't been to the track yet this year but I think my 60' times would drop if anything since I use to have 100% 97 GT rear end to a nearly fully build IRS.
One noticeable thing is with the extra weight in the rear I've noticed 2nd hooks better where as I use to be able to loss it a little (not while shifting but while cruising in 2nd and just stepping on it).
Only thing left is the front K-member upgrade, solid steering shaft and maybe coil-overs =)

Koni Yellow sport adjustable rebound struts and 300# 10" springs should nearly complete my handling needs
well maybe some cooling ducts for the front and ive been playing around with the idea of making rear cooling ducts out of the rear fake side louvers that serve no function other then looking cool (no pun intended, haaaa) we'll see where the winter takes it.
