4 Pot Princess Caliper - What Brake Disc ?

[Pigboger]

Sorry if I am getting boring on this subject but could still do with some advice.
I have the calipers all sorted with new pistons/seals but what disc ? I beleive the ones on the car are Ford Granada ventilated. However, the pad only covers part of the disc. About 10mm is free from contact. I beleive that the 400SE used the same Lockheed caliper 3247 2070 and the disc and caliper married up exactly.

What were those discs please ?

Thanks in advance...

Ohh, 1988 350i in need of lots of attention......

The original setup used AP Bells and Rotas. I'm not sure of the size but they are a larger diameter than the Granada disks so there is no pad overhang. They are also thicker so the spacers in the caliper may need to be altered. The bad news is they are very hard to obtain but this may help http://www.ebay.co.uk/itm/121396753930?ssPageName=...
Probably cheaper to buy this than have the rotas made.
