Which brake system take over 302mm?

Hy, have for years found the 16″ (302mm) brake at the VA and with ATE (for 3 years the one with the cut) actually a good brake. Now with a little performance increase, this is still ok for the normal traffic, but if you get out on the track, several times what comes out (because you can’t look or don’t want to guess anything) it is already brought to the border. What is the next bigger one, which also makes sense, and does not have an imbalance after 3x brake or vibrates? I know there’s an original 17″ version, but I don’t think it’s much bigger? Thanks in advance for your info! V70 / 99er / Mod.00 lg Jerry
