ok... the brackets mpfab used are the rs ones though, right? He has a non rs that he put them on though I do believe correct? Why couldn't someone swap drums on a non rs to the sonic rs rear disc parts then. I know that the "axle" in the back is a different part number from rs to non for some reason and I though it had something to do with the fact it has rear disc.
That is what I am doing. Rear axle is exactly the same. Drum parts will come off, and these, along with calipers and rotors, will go on.
