944T Rear Brembos on an 84NA hub/disk

[matara]

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.

the boxter 's'/996 rear rotor is 299mm by 24mm -70mm high
-so its the same as the 85 turbo?

-how does it differ

-plus its drilled?
use an adaptor and run the radial mount 996 calipers

OH i seeeeeeeee

-the 996 disc although 299 and 24mm, is 75mm overall height!!!

hmmm -does it still work ok?

-got adaptrs for 996 rear calipers/???
-no i am worried they wont work

[pantswagen]

i'm confusing myself now
-the 85 disc is 298 by 28mm -70mm high
-so the thinner-24mm disc

--must just get 1

944T rear - 299x24
Boster rear - 292x20
Bosxter 's' rear - 299x24

With the 944T rear rotor on a 944NA rear setup, you need a 3mm spacer and longer caliper bolts. With the Boxster S rotor, you don't need the spacers. Both rotors will work with the 944T rear caliper and the 944NA brake shoes and hardware.
