944 calipers on 951 aluminum arms, which rotors?

[boygenius]

I thought that 1985.5 through 1986 was the early aluminum arms and 1987 and later were the later wider arms.
Here are my trailing arm numbers to see if they help clear up the trailing arm info.
Left part # 951.331.513.0 and 302.948.0.00701
Right part # 951.331.514.0 and 302.947.0.00701
It looks like they have both turbo and non turbo part #s on them.

There are no part #s left on the rotors if there were any to begin with. My suspension is all from a 1987 944-S. To the best of my knowledge there is NO difference in the brakes between the S and regular N/A. I often use www.pelicanparts.com to cross reference part #s to see what fits. When you go to buy rotors check out www.autohausaz.com, they have some good prices on german car parts.
