[Xr302]

Hey guys,

I just posted this on a different thread on this forum but this thread had as been used a bit more recently, so I just thought I'd try here too.
I have a au2 xr8 I have recently fitted front premium brakes off a ba xr6 turbo, they are 325mm x 32mm and apparently use a c4 caliper.
I obviously bought them second hand, when I fitted them, the pedal was terrible! It nearly has to be on the floor before the brakes work... The old 287s worked better but they were warped to the **** house...

Has anyone that has done a brake upgrade had this problem or know a fix for it?
Cheers 👍🏻
