            310mm then to answer your question!! I would also recommend ditching them. I have the ufos too but I'm currently waiting on Corey to finish my Porsche GT3 brake conversion so I'd recommend you have a chat with him!

                    You may well do - dunno if the HP2 on the A8/S8 is same as UrS4 - I have a set of HP2 from UrS6 that was in a breakers some years ago. They have been in a box for ages - horrible looking and partially disassembled - needing new seals etc and a lick of paint. You (or anyone) can have them for free - just postage to pay.

                    If I end up rebuilding them myself then I'll need some money for them - unless they end up serving as spare HP2s on my Allroad.

                      HP2's are the same between S8 and urS4/6 (except the S8 version is aluminium), no HP2 setup will bolt onto the UFO strut, neither will the 314x30 disc as the UFO hub is a different diameter.
                      HP's became standard on the S4 late '93.

                      If your disc has (as you described) a metal cover over the disc then you are looking at the mounting for the UFO disc.

                        Oh yeah - the sturt is differnt - totally forgot that. Stupid UFOs - does anyone rate them at all ?

                        Anyway - offer for pair of HP2s still holds for whomever.
