Yes, if we look at the pic it's definately the old S3 but I see often over the ebay pics representing something else so I just wanted to be sure. In the meantime, I've checked on compbrake page and the kits are 850 pounds there. I wonder how good could they be, knowing the big names are twice that ! Compbrake has also an unusual disc thickness of 32mm for only 330 in diameter. Most others are 330x28mm.
