Couple of questions for you-

Are piston diameters about the same, roughly?

Also, for 200q20v and S-car owners, are the A8 calipers easily 
swapped for the stock calipers?

Can you get the carrier bracket with the caliper, or separately?  The 
pins on my 200q20v are ever so slightly bent and I had to sand them 
to eliminate notches that were causing binding...so ideally these 
need to be replaced, but the pins are not available separately, you 
have to get them with a carrier, and the carrier isn't even available 
separately!

E-brake similar in style?

I ask, because I've just about had it with the POS design of the 
original V8/S-car/200q20v rear calipers...and hey, a few pounds 
weight savings couldn't hurt, although it isn't exactly the rear that 
suffers from unsprung weight in a UFO-equipped 200q20v :-)

Thanks!
