These are on an '87 Guldstrand Grand Sport 80 I just bought. The spindles definitely are pre-'88 according to the part number on them. Looks real factory. Maybe Camaro 1LE?

Calipers look like the later JL9/C4 offering. Is the rotor just short of 12" diameter? A snapshot of the outer would likely confirm. The "cast" adapter would have been a "high volume run" offered by many. I wouldn't think 1LE because I thought the caliper bracket was different when that caliper was used on F-body. Hydraulic fitting location maybe also. Those GS80's were built later after J55's were introduced so if it's a 13" rotor.
Hub and bearing hardware appears "substandard" and incorrectly mounted, OE I'm quite sure is nutted on the spindle back-side.
Considering it was Guldstrand maybe everything came through Baer

I'm guessing you're right and that's an earlier Baer bracket setup. You're also right about the hub bolts being backwards compared to oe. Don't know why they did that, but this is a track car and doesn't have the dust shields either.

Pretty sure it's J55/13" rotor as that's what was in the Guldstrand paperwork. I'll measure to be sure, but I can't snap a pic of the other side yet as the car's in a warehouse away from my tools.

What might be interesting, compare the rotors to the later J55's if it's a 13" rotor. That would confirm whether it's a 100% Baer package or just some adapters and the later J55 package.
