Gumby, what springs and shocks are you running?  Is there a spring I can run with my fox mustangs shocks just to get by with the IRS until I get an MM coilover kit...

not that i have seen, but the spring is a 5.5" coil very similar to the generic springs most circle track guys run. so you can feasibly get any rate and free length you want from a race shop that sells coils.

well, at that rate I'll probably just aim for the coil overs straight away, especially since I'll be halfway there after buying the Bilsteins!

as you wish.

FWIW, the circle track springs are pretty inexpensive; added to the fact that i dont like the idea of single shear coilover mounts, and you see which direction i will be going

either of you guys know how the ABS is setup on the IRS?  for example, the solid axel has tone rings on the axels themselves, and then the abs sensor bolts to a bracket next to the ring...  can you compare this to the IRS?  I'm just trying to make sure the IRS I find to buy has all the necessary pieces so I can connect the ABS.

also, how hard is it to change IRS wheel bearing (compared to the stock original TC type front bearing)?

ABS tone ring on the IRS is located on the inside stub of each halfshaft. you can see it in this pic. the sensor bolts to the side of the differential case.




IRS wheel bearings are sealed units, pressed into the upright.

they are sealed? huh.  any idea how hard they are to change?  Sounds like you need a press to do it...?  upright; is that kinda the rear's equivalent of a spindle combine with the hub?

And one other question:  do you guys know i the v6/gt brackets, calipers and rotors will work on the IRS.  I know they are interchangeable on the solid axel but I was told they aren't on the IRS.  Why?  I ask because I already have the base brake setup and I found a great deal on an 03 IRS but is has no brakes...

The Cobras used vented rotors but the same calipers, with a thinner brake pad to take up the difference in the rotor thickness.  The standard rotor on an SN95 is solid, unvented.    They'd be a big step backwards, but that's not a problem because all you have to do is get the right rotors and matching pads.  Everything I've ever seen says the calipers are the same.
