Simple question, simple answer. I want vented rear brakes.

    Simple question, simple answer. I want vented rear brakes.

    I've done some searching, but I keep coming across people going crazy with z32 brakes and whatnot, and since my driver rear caliper is currently sticking on my DD '85T, I need an answer FAST. All I want to do is install the vented rear disc brakes from the '87+ z31s, and I want to know if it is easily done. My research says even the NA cars had vented rears after '87, and that those are better brakes than what my stock Zenki Turbo has. I remember my old '89 NA braking painfully hard, so that's all I need. Even if someone has a link to a forum (That isn't broken, like the ones I found!) I'd be happy with that. I plan to replace the calipers, lines, and rotors no matter what, so now is the time to do this upgrade. Any info you have would be great. I'd guess all I need is the kouki rotors and calipers, but I don't know for sure! Thanks in advance!!!

    You'll need 87+ rear trailing arm assemblies, the hub and caliper ears don't match up if you try to use 87+ rotors and calipers on early ones

    They can be made to work as can anything, but if you want simple, just do the swap.... if you get non-turbo arms, you'll have to swap over the axle companion flanges from your zenki arms

    Gah. Of course it wouldn't be simple. If memory serves, the kouki rear trailing arms kick the rear wheels out a bit more, too, right? I don't think it is much, like a half inch or something, right?

    I'd do it if someone had a set of trailing arms laying around and the shipping wasn't horrendous, but I doubt that will happen. Those have got to be pretty heavy.

    I think I'll stick to the stock stuff. I need this done fairly soon.

    Also, thank you very much, G-E!

    Buy 2 part brake discs. You might need to order custom center pieces, but you after that you can use your stock parts.

    I Installed 87+ calipers and Jag X Type Rotors on my 85 T Rear arms

    Can read all about it here....http://z31performance.com/forum/basi…on-to-your-85t

    Its a bit of pissing around.

    When i need new rotors I am going to order standard size Race rings and have hats machined up to suit them.
