Anyone had any experience comparing the Tamiya Alloy hubs vs Aftermarket (3Racing, GPM, Yeah Racing)

ive never had much luck with yeah racing from a quality point of view with other items Seem ok at first, but often are soft or ill fitting. But worth a look especially as 1/3rd the cost!

looking at;
- rear hubs
- motor mount
- centre shaft
- steering

so the usual really.
