Just phoned this breaker after seeing his auction on eBay for a side light bulb from a 1999 S1. Item no 140078022904
He is breaking it, but the disks look like MMC's in the photo, so I asked him to put a magnet on them, and they are not steel. Got him to check condition and he said that they all look good. Pads were also good.
Got them for £30 each + VAT, including delivery.
If anybody needs bits and pieces, I think it has had a rear end as well as a part frontal, give him a ring on 01366 501321 .
