944T Rear Brembos on an 84NA hub/disk

86 only 944t rotors. 24mm

The hubs have to match the rotor. So, with the early hubs you can only do the early NA rotors. The 86T front rotor (28mm)will bolt to the early NA hubs, but because of the offset difference on the hubs, the rotor will be way too far inboard and will foul on the steering arm of the spindle.

Why not just keep it all the same (ie Turbo front rotor with turbo front caliper and matching hub)?

The other option is late 944 hub (87+) with boxster (1st gen) rotor and 944/993 rear T caliper in the front.

I should have specified this is for the rear of the car, not the front.

The fronts are all 944T with Lanners kit. Its just the rears that use the 944NA hub, and I want to use the 944T rear calipers to have the same look 4 pot calipers all round.

That clears thing up. In retrospec, I should read the titles first....sorry.

Use a 86 (only) T rear rotor, 86+T rear caliper. Everything bolts up, and typically need a small spacer (about 3mm) to center the caliper on the rotor. The later (87+) rear T rotors have a different center bore, so they technically fit but then the centering of the rotor is only done by the setscrews; not the ideal situation. The 86T rear rotor is the only one with the correct center size for the early NA hub.

A little late in the conversation, but you can use the boxster s rear rotor, and then you don't have to worry about the 3mm spacer.
