were there any circumstances where a posi rear was mandatory when you ordered a camaro with rear disc brakes?

 

from 1987 on if you wanted rear discs you had to get posi also, it was part of the package options that were availble those years. Prior to 87, posi and rear discs were seperately available options.

 

My 1985 sport coupe came with a handling package and rear discs and posi were part of it.

 

Yes, but posi and rear disc's were seperate options from 82-86. There are some members of this board that have non posi rear ends but still have rear disc's on their 85's.

 

Okay. My 85 came with the F41 handling package. It's a poor man's Z/28. Posi and 4-wheel discs included. Unfortunately, the rear discs are the iron Delco-Moraine style.

Never hear of that, does anyone have anymore info on it? Thanks.

Originally, my '85 came with an open differential, but with rear disc's (J65).

 

Gearhead...,

I guess the only thing you need to know about those iron calps is to avoid them. They were the subject of a recall in stick shift (but not automatic third gens). I've got the PBRs in my garage and Dyno Don has a 9 bolt sitting around. All I need is the money.

AFAIK, the posi and 4-wheel discs were standard with the F41 sport suspension.

 

Those iron calipers are GARBAGE. Ask me how I know this.

Anyway, I'm yet another 85 owner that had disk brakes and no posi.

 

Okay, Jim, I'll bite. How do you know that?

 

Let's just say that my stopping distance would be considered "good" for a fully loaded log truck. For a sports car, not so good.

 

Curious on the recall of the iron calipers. What was it exactly, and what did they replace them with.

I guess I better find out if I have any outstanding recalls on my car.

And yes I also have a non-posi with the rear disk set up.

 

So I take it Auto Rear disc brake cars got aluminum calipers??

Kevin

 

Unfortunately, no. My '85 has those ***-forsaken iron calps.

 

So what 85 86 rear disc cars did NOT come with iron rer calipers?

Kevin

 

I have a an otherwise fully optioned 92 Z with G80 Posi and J41 rear drums.

 

None. You had to wait for the PBR setup in 1989.

 

Then whats this all about??
