    HP2s have 4 (smallish) pads PER caliper. I only see two (one per side) in your photos. Most likely Girling G60s if two piston or G54s if one piston.

            Just for fun, photos of UrS4 UFOs, taken by Gary B. (UnicomS4), labeled by me.

              I have Girling 54s on my 98 C4 A6 avant. I recently "upgraded them" using Audi TT quattro front brake caliper carriers and A8 312 x 25 rotors based on this DIY:

              http://www.audiworld.com/tech/wheel1.shtml

              It was a direct bolt on plug and play. Works fine behind 16 inch UrS6 Avus (my summer wheels for the 98).

                Was the colour Ocean Blue or Royal Blue?, I forget now..

                  The sport seats look similar to the UrS4/S6 seats but with fewer pleats in the back and bottom.

                  As for the colours, that is why I asked for the colour code.

                    Arh yes, I think it is blue pearl Z5T now I see the list, there was a touch up stick somewhere with the car, but it might have gone to the new owner at the time..

                    Interior is ecru, beige, apparantly the seats having only one/two panels are quite rare and were another option Q1D?

                      I was going to let is slide but, I can't. Labelling HP2s with "Porsche" is just wrong. If you want Porsche Brembos, e.g. 928 GTS big blacks, then buy and install them. And besides, Porsche Brembos in my experience are labelled with white letters. Red letters on HP2s is just tacky/gauche/rice.

                      Oops. Did I say all that out loud?

                        Q1D is sport seats. Should also be N0K = leather with the HQ = ecru colour code on the build tag (in the position where it says N2G/CK on this tag
