A mate has these on the back of his Corolla rally car. Had believed they were Volvo 140, but I gave him three different types of 140/164/240 rear calipers and they are all wrong.
The known Volvo calipers have a bolt spacing of "about 80mm", his calipers have a 56mm spacing.
Note also that his calipers have been widened with a spacer between the two halves, so they fit over a wider rotor.
