Front brake rotor/hub heat insulator/isolator.

[69427]

While waiting around for the weather to warm up so I can get back to working on improving the idle quality of my antique, my mind wandered to a short project to do in the meantime. I'm thinking on making a couple .040" titanium or stainless (whichever machines easier) rings to insert between the rotor hat and the spindle hub, in an effort to reduce the heat transfer from the hat into the (C4) spindle bearings. This obviously isn't a perfect heat isolator, but it should be directionally correct to make life easier on the bearings.

I'm going back and forth with the idea of putting similar rings between the rotor hat outer and wheel inner surfaces. Not as important as above on my list at the moment, and I need to first see how much of a PITA these rings are to fabricate.

Sounds like you are looking for Very Thin wheel spacers. Just a different position--between the hat and the hub, vice the hat and the wheel.
A bit thicker - but you could try some thin spacers ~ 0.25 maybe 0.125 to test the idea? Might need to trim the overall diameter.

OR - What about just using a set of 5 (each wheel) wave (spring) washers. Blank space = no direct conduction of heat. Just convection. 080 compress to 040.

These might work.
