I break axles now and then... but I'm still using NAPA OEM axles. :chuckles:

I haven't broken anything else though. I'm more aware of the lifespan of parts though. For instance, I'm changing the head gasket/timing belt/tensioner, bolt, spring/intake manifold gasket very soon. Going with a 6 puck clutch now too. If you build it right, you will be just fine when it comes to parts. Your tires will wear out faster.
