topline front disks + cb rears !?

I have Topline's front disc brake kit. Works great and the people at Topline are very helpful. I have heard that CB Performance has the most complete rear disc brake kit on the market. They have generally great products. When I get rears I am set on getting them from CB.
On the other hand, if you want to go all out or need the best stopping power, go for a Porche conversion.
