Was originally going to upgrade my brake master cylinder to brembo rcs corsa corta 19mm. Until a buddy of mine told me that i should get galepeed master cylinder since WSB prefer to use the gale speed over brembo rcs corsa corta. Also there are some price difference gale speed being a little bit more expensive. i've done a few research here in there and youtube that galespeed had better reviews that brembo corsa corta but i could not find anyone here with SC77 with gale speed master cylinder? TIA!
