I'm in the middle of the toyota/300zx brake upgrade on my 71 240z and I need a wheel spacer. No one in town has one. My spacer needs to be about 11/16" to make my 300zx vented rotors line up with the caliper.

When everything is aligned correctly, there is a very low clearance for both the caliper diameter (1/8") and the width (1/32 each side). There is plenty of room for pads, but that area above and below the pads where the rotors pass through the calipers is very tight. Its not rubbing. I wonder if its too tight.

Since I can't find spacers locally, I put 10 washers on each bolt to create the space that I need between the hub and the rotor. This setup doesn't seem safe to me. ]!!!!!!!!!![

] = hub

[ = rotor

! = washer

The washers and bolts are hardened steel, but something about this setup makes me uncomfortable. It looks ok and it works, but I have visions of bolts shearing and my Z skididng to a stop as the rotors dig into the pavement. :eek:

What is wrong with using washers as spacers? Any comments?

How much clearance do I need between rotors and the calipers? Do I need to have the rotors turned a 1/16th or so?

If the bolts shear, I guess the wheels would still be attached to the hub.:stupid:

The rotor would just be free wheeling.

Thats a scary scenario too.

You can find the spacers on ebay from user JSKinnovations. I have the vented setup, and 11/16 seems too thick-I want to say from memory my spacer is about 3/8" I can check tomorrow if it would help.

Don't forget the braided steel lines!!!
