-here you can see with the rear disc spec the difference in the 85/6 only discs and the later typpppppppppe

-late 944 disc 100mm
-85/6 alloy arm - 70mm

-30mm increas in track
-86 arm is same as steel arm with 22mm spacer

-so 87 alloy arm = 52mm wider track than bug
-86 if its the same as steel with 22
-simply increases the track 22mm
?

-also note steel arm disc is 289 by20mm

-where as 86 alloy arm is 299 by 24mm -4 pot brembo

-also worth noting that the late 911 uses the same disc? -299 by 24 -but as standard is drilled?

now i think i have answered my own question
-i have the adaptors that take these arms to monblock bremboo's
-now i reckon i will need boxter 's' calipers rather than the smaller boxter ones, as they seem 289 by 20
ho hum -does it mean i can do either tho?
-ie if i get the small engine boxter calipers -fit the 289 20
-if i get boxter or 996 - get the drilled 911/964/

-coolio
anyone have any calipers for me?
