I got 4 calipers for about 500€, which is cheap, considering they're pretty much flawless and because car parts are expensive here.
The cheapest disc's I could find were 20€ a piece, about 25-30 bucks.
The calipers are indeed very thick! I will need at least a 15mm spacer to fit them in my Work Equips.
I'd Imagine 6UL's needing much less of a spacer.
How these would work on the track I'm not that sure, I'd say the brake balance would be off, but you might be able to remedy that with a balance valve.

 

I finally got to fitting the Big brake kit. Thanks to Sandro for the inspiration :P!
They brake quite well and look pretty bad *** imo.
Once I finish up my 1.8 swap I'll look into fitting the rear calipers aswell.

Any more information about the brackets with the poor thread engagement from 2 years ago? I think the traditional BBK would be easier but it is pretty baller to have Porsche brakes. Are the full ceramics the same size?

 

I used a piece of angle iron with alignment bolts pressed in, now I've got all the thread engagement I could ever need :P.





The full ceramic discs are absolutely massive and will probably need 18" wheels minimum.
Also you'd have to machine a custom center for them since the Porsche offset and bolt pitch circle is way off.

 

Those Porsche brakes look very cool. Props to making something like that work .
