These are what the spacers are for really. to fit the 300zx 4pot Calipers and rotors.As of now the car is constantly being changed and I have now aquired a daily driver and will be building the Primera more for racing, most interior will be out and all a/c stuff has been completely removed.However a small fire had broke out inside the car on the driver side minutes after I arrived to work. Good thing that the security was quick and had out the flame by breaking the window to get access. I have done most of the repairs and the main left is to find a replacment windshield because mine now has cracks all along the glass. The car is now running and ready to compete but the Glass is what is holding me back. Here is a pic of the cr after the fire:
