CPP Brake Conversions

Thanks. My plans are to put 15x6 wheels on the front and 15x7 on the rear. Nothing too radical. Scarebird is the name of the company? I'm heading to google and again, thanks. I was about to plop down my hard earned money on the CPP kit and then I saw all the people on other sites, Chevys, Fords, Chryslers all who had nothing but headaches with them.
