I agree the existing 991.1 GT3 calipers are too heavy. I see larger back cut outs with the new design which should offset a fair bit of the increase in mass. I agree Porsche have Brembo on a budget here but it would be nice if they were able to lighten the caliper using the same techniques as the Radi Cal set ups that Racebrakes and others sell. Ive looked at about a dozen images of the new caliper some fairly high resolution and it does seem there is a deliverate design change here - hopefully for easier pad swaps and its obvious for better ventillation....
