944 brembos - which year calipers are these??

[djmatio]

Hello,

As I am about to re-finish (powdercoat) my 944 Brembo calipers prior to installation and I noticed that two of the calipers are wider that the other two on the inside where the rotor would go. I have a feeling that the porsche parts dealer sold me 2 86 Turbo calipers and 2 89 S calipers. Could some please help me confirm if this is true? Since there are a few different types of 944 brembo calipers it can get confusing.

Pair #1 info:
inside markings: 86 20.46.73.00
width inside caliper housing where rotor would be (near bottom brake lines): 1.410" or 35.56 millimeters

Pair #2 info:
inside markings: 89 20.4892.00
width (same place): 1.551" or 39 millimeters


I know this is not much info, but these markings are stamped on all calipers of the same year and type. Hopefully someone has seen them before.

Thanks
