Spider wheel brake discs

[David H]

Does anyone know what brake discs are used by the factory for the spider wheel conversion?

The fronts are larger discs I presume, but the rears are standard size, do they just drill out the holes to 5 stud fitment or are they different disc?

I'm doing a spider wheel conversion and need new discs all around, I want to keep the rears standard size and maybe the fronts as well. But I may increase the size of the front discs and space the caliper out.

Can anyone help me for any of the above?

Rear disks came with only 5 holes (ie were not drilled out) apart from that exactly the same as later cars. IIRC they also came in AP boxes, so I would guess a standard fitment from something else. Rear disks were plain vented, I had mine grooved at local engineering workshop.
