I just bought a project car and in a spare box I found a complete front and rear RZ brake kit brand new. The kit has Precision 2 piece rotors, JDM dust covers and all new mounting hardware. Here is a few pics. I sat the rears on the car to see how they looked.
Wanting to see what they are worth.

 

Your best bet is to run a search in the parts for sale section, and note which pairs sold. Nice score.

 

When you decide on your price pm me.

 

Won't be brand new, Mazda doesn't paint over the fasteners, evident on the fronts. Good score none the less.

 

They are new RZ's. From what I have been researching the RZ's aren't normally red, just the Spirit R's. These must have been coated after purchase.
