Caliper differences?

[Johnwindwood]

Guys

Are 1.9 calipers different to those for the 6 cyl cars? I see that rebuild kits do the whole range but there are different part numbers for the caliper. Anyone experienced this?
Thanks.

1.9 calipers are for solid brake disc
6cyl models have vented front disc same diameter bit wider so wider calipers and caliper carriers to match.

Looks like the seals are the same for all Z3s apart from the ///Ms.
