I have a couple of sets of those as well. No problem if you use axial to radial adapters and radial mounted calipers. The '86 turbo calipers have a axial 94mm. bolt spacing. The NA spindels have a 76mm bolt spacing.
I've tried making steel adapters 10 years ago but it was to heavy.
The '86 turbo front disks are the lightest 28mm. disks.
And with the original '86 turbo spindle and caliper there is no need for an adapter and 2 more bolts.
I want to weigh the difference between the front beake setup on the red 1303 and this combo. Both use the same disk and brake pad size so there is theoretical no difference in performance. The weight difference is why I wanted to finaly complete this setup.
