irs??

not an rx7 but heres mine... not the best pic.... its a ford supercoupe 7.5 with kustom werks control arms

what did you have to do to the drive shaft to get it working ?

I used a drive line out of the super coupe for the back and then used a part of the mazda drive line and then made a sleave that fit in the super coupe one and the mazda one fit in the sleave (my dad has a lathe so it was easy) i put every thing together in the truck and used a dial micromiter to tack it together and spin it to make sure it was staight. and then final welded it. It came out really good but it took me like 4 hours to do. I am planing on taking it to a driveline shop and have them make sure this one is perfect (needs some minor tweeks i think to be staight and then balanced)or to make me a new one.

I have an Rx-7 IRS in my mazda b2200. No pictures except for the camber you can see in pictures.

Since I also have a 350 chevy small block I had a larger diameter driveshaft made from scratch. Cost was not bad $180. Came with brand new front joint and they used on rear a older dodge mounting flange they said. Bolted directly up to the mazda 4 bolt flange while allowing me to carry a stronger joint.

Hope that helps.

thats dope thats a really good price too post some up of your truck

hey to all you irs guys what did you do with your wheels is the spindles on the rx7 also six lug or what did you guys have to do ??

are the rear ends the same for all the gens ???

no ones got any imput on this ???

I went 4 lug all around instead of the standard 5 lug. I then converted the rear to posi.

No they are different. The 5 lug later version has different hubs/brakes etc although they bolt onto other version. The center section is the same just depending on which gearing/internals you want. heavier center section with 3.93 gearing.
