Real ARCADE controls should solve your problem.
I don't know what's in the guts of the Xbox wheels because I've never disassembled one.
I'd assume they are pot based, just like the PC versions though.
If that's the case, you should be able to hack the above mentioned pedals, and a Happ 270 wheel to them, and get much better durability/feel, without resorting to trying to retrofit arcade sensors to a real car wheel.
I've got a Happ 270 wheel, and Happ analog pedals.
I used an AKI to interface them because they are used only on my PC though.
