Small rear calipers

I've just come across the common issue of lifted spring plates when changing the pads in my 2 pot rears. The existing pads had been put in by a Porsche specialist and had clearly been filed down to fit. I believe this is common practice. However when looking up the part number on PET, the pages for these calipers indicate that the spring plates are not fitted. Yet spring plates are fitted to mine![&:]

What am I missing here? Was there a redesign of these calipers? Even if this was the case, mine is a 1990 C2 and there's no record of the calipers being changed. It even begs the question of whether I need the plates at all especially since later Porsche models (e.g. my boxster) don't have spring plates.
 
Sorry I can't answer your question but I would say that you'd be better off ditching the weedy 2 pot calipers rather than reconditioning them.
I had the same problem and switched to the beefier 4 pot callipers from a later 964.
A little more money (about £150 for the callipers) but braking is better and I can have a much wider choice of pad when it comes to replace them.
 
I'm hearing you loud and clear Kdean. If I could find calipers for a similar price I'd buy them but it seems they are like hen's teeth[8D]
 
You could try standard 993 rear callipers. Thay are much easier to find secondhand & they fit under 16 inch D90 rims without any fuss.

Good luck

Thanks Rob,

Go ahead and bid. I'm not going to bid on this pair as a) I'm happy how my little calipers have cleaned up and are performing and b) I've got too many other things to buy at the moment - ordering a secondary silencer this week to get the noise down for trackdays (and the neighbours[8D]) and I may need front struts very soon. Upgrading calipers can wait until next year for me.

BTW in response to my original question, I've now found that although not shown on PET, the little calipers have 4 mini spring plates inside - these are nothing like the spring plates found in 4 pot calipers.
