    If it's anything like the front wheels you may have clearance problems with the caliper hitting the wheel. Interesting idea though, wonder if the bolt spacing is the same? also I presume the calibra turbo used the handbrake on the caliper setup like the Astra?

    If the Cali ones are anything like the Mk3 Astra 2pot rear calipers, the I doubt they'd fit easily.

    You have to change the whole hub assembly over (if it even fits), as the rear discs incorporated a independent cable operated drum hand handbrake, unlike the Mk4's all in one.

    Plus they are an absolute bugger to service as you couldn't open them up to get at them.

    IMO there's op point upping the rear braking anyway

    All Calibra's have the same set up as a Mk3, ie handbrake shoes inside the rear disks operated by a cable.

    The turbo will be 5 stud and the spacing will be the same.

    Not sure how they mount compared to a Mk4 Astra though, as the Calibra has independent rear suspension. And as it is a turbo there will be a driveshaft in that area aswell.
