A lot of people track with the various rotor options available on the f8x, f87 and f87 Comp from Girodisc and Paragon. Girodisc and Paragon rotors are used on CCB/2NH Front 400x36 mm (there’s also a custom machined hat and caliper mounting brackets to run 380x36 front rotors so 18” wheels can be used) and rear 380x30 mm setups, and the Blue front 380x30 mm and rear 370x24 mm setup. I’d guess it’s probably 70/30 on Girodisc vs. Paragon mainly because Girodisc was first to market. Also, FCP Euro offers Girodisc rotors so you can get replacements through their warranty program (not sure they carry StopTech rotors). There is a group of people running Paragon’s e9x M brake kit as well as stock 370 mm and 360 mm replacement rotors from both companies. Both brands have extensive track use so you should be fine with either option but, if I had to choose one, I’d go with Girodisc because they’ve been on the market longer.
