I was just reading about these brakes but I was looking at the step up rotor, the R1 Carbon series since the price was only a little bit more. What I really want to get is a BBK from CEIKA. I'm not sure that I need them for my Corolla iM 6MT but I want more stopping power for my 2009 Corolla S Turbo 5MT.Installed R1Concepts (Eline Series). I used the same brand on my supra.
Its been a year now for my supra and about 6 months on the iM. I can't even say anything bad about them. Just avoid wheel cleaning products (bad for brake parts). This way, the zinc coating will be preserved.
