I have owned my WRX for just over 2 years now and this is going to be the second time i've replaced the rear discs because they are badly corroded!!! The inside surface of the disc is almost non-existent it has totally flaked away and the discs are only 1 year old. The discs I put on last time were Black Diamond grooved discs. Has anyone got any advice on how to prevent this or a brand of disc that lasts longer!!. I was thinking of trying EBC turbo grooved discs next has anyone tried these??
