If the side plates are indeed aluminum, then I completely agree with you. Aluminum has a 270% greater thermal expansion rate than TI...

Honestly, you'd be better off making the casing and side plates out of the factory cast iron, or stainless. Grey cast is 5.8, Steal cast is 7.0, high grade stainless is in the 5.5 range, TI is 4.8, AL is 13.0.

I would be fine if they made the bearing core out of TI assuming you still pressed in a factory bearing. It's not a friction part.
