I‘m looking to upgrade the rear calipers. I could change discs and hats if necessary, but would much favour a setup that retains the oem discs and hats. The calipers should mount without brackets, look more or less period correct, not have markings that would blatantly identify them as not oem and preferably be oem on a car. In other words shouldn’t be recognizable as „not oem“ by the untrained eye. I‘m not too keen on aftermarket suppliers. I’m open to suggestions for the handbrake. I know it‘s a tall order, but perhaps some of the more experienced and knowledgeable in the forum can help me out.
