I have a 92 Z and was told the rear brakes are the same as 1LEs. I have C5/Z06 fronts and would like to go bigger on the rears also.

Question, do I have 1LE rear brakes, if not what about LS1 rears?

I don't see anyone with a rear package, is there one?

Yes, your rear brakes and 1LE rear brakes are the same. LS1 brakes aren't any bigger than the ones you have right now. The only advantage to the LS1 brakes is that they have a better designed internal parking brake setup. Probably the only way you could get bigger rear brakes would be to go aftermarket, such as Wilwood or Baer.

 

the rear disks on 89-up cars are PBR calipers. Which are the 1LE brakes. Ls1 rears can be put on the rear although I don't know exactly what needs to be done as I just swapped in the entire rear, it gave me a brake and gear upgrade all in one. Ed "ebmiller88" sells a package to upgrade the rear brakes. to whatever brakes you want I believe haha. And it's alot cheaper than aftermarket, also parts are readily available. He may ring in soon.

 

Here...as said above, '89-92 rear discs on all cars are 1LE spec, all the same. I do offer complete rear disc upgrades that will bolt on, soon to offer totally bolt in LS1 rear discs as well:
