AC MKIV Brake rotors

I have a 1984 AC MKIV with 733 BMW calipers. The front rotors are 11.5" in diameter, 7/8 thick and ventilated, 6 pin threaded to hubs, 1/2 inch tophat, 1" bottom offset. They're not Beemers. Anyone have an idea what they might be? No numbers are stamped.

Thanks,
Bill

Bill, I'll put in a call to MKIV, he has a wealth of knowledge on these cars. I'd like to know for future reference as well.

mod note - moved to All Cobra Talk

Steve Gray at Brooklands has the rotors. They are based upon production units, but are modified. Steve has had a new batch cast and machined.

Hi,

I am new here and I can tell you something about these rotors. Although the calipers are standard BMW (front), the rotors are speciall made for AC resp. Autokraft in the 80th. I don't know whether Steve still has some rotors but Gerry has made some new last year or the year before.

Regards,

Peter

how bout the front brake hoses. they have Girling written on them but can't read any kind of numbers off of them

we matched the threads and used steel braided lines. --
