Looking very ripe and juicy 
The calipers arrived back today. They look better than new - seriously impressed!
Other odds and sods that have been going on...
I've recovered the long center console and re-carpeted the console 'hump', the cover down the side of the bonnet release handle in the footwell and the cover the other side in the footwell.
Really scratching about for things to do. Where IS that fibreglass engine tin!!!!!

The calipers look incredible. Too good to use! Was that http://www.porschecalipers.co.uk?
Don't want to alarm you but the rears look 993 to me.

Nope, it was Jonny @ http://www.brakecaliperrefurbs.co.uk
It was somebody on here I think put me onto him. Great service and excellent quality of work.

They're 993 C4 rears. Why, whats the issue? 
Research on here suggested they're a good replacement for the old style twin pot rear calipers the car came with.
The rears are in the back ground in the first image and fore ground in the second.
You've got me worried now! What have I missed?

I think they're a good replacement for the 2-pots! Sorry, I thought maybe you had been sent the wrong calipers, as assumed you would have asked for 964 4-pot rears....

Phew thank ph*k for that 
I couldn't find any of the later 964 4pot rears, but these 993 C4 rears came up on ebay so I grabbed them and had them reworked.

This knowledge is all from reading Bill Verburgs posts.
They don't require any adaption but they will increase rearward brake bias as the pistons are marginally bigger.
As to whether this means much on the street, I dont know. What I would do is to ensure the brake bias is moved fwd.

The extra pistons make the caliper less hydraulically efficient, so they will have less clamping force than the little 2-piston calipers they replaced.
The OEM way to fix this is to swap out the 45bar proportioning valve for a 55bar unit.
The more economical way to fix this is to remove the guts of the 45bar unit. This will give the most rearward bias. That's what I did when I upgraded to 4-piston rears and the car feels good during the handful of autocrosses I've done since the change.

Well done on sorting the seat belt fitting. I also used spacers to get them to fit (I wasn't around when you were asking the questions in your other thread). Before discovering the spacer solution, I used the rear seat belt receivers because they are flexible but they weren't ideal because they sat a bit low in the seat hole.
