86 944 rear rotor size???

[oicdn]

Curious...on Vdubcustoms website...it goes 83-85 na....then 87+Turbo....

What is the size of an 86 944T rear disc rotor? Do I just use an 83-85 NA rear rotor?

I'm finishing up my brakes and need rear rotors. I was actually thinking of buying a complete set of X-drilled or slotted rotors, but considering I have 87 fronts, I'm kinda mismatching a bit here....so I'll just wait till I need new ones considering the front pads and rotors are still in GREAT condition...why buy new ones, when they work fine????

Anybody know the size???
