If a wheel cracks from normal use, then surely if you get it welded it will eventually just crack somewhere else?
In that photo above it's been welded 6 times - probably spent more repairing it than it would have cost to buy a wheel that won't crack unless it's subjected to forces out of the ordinary?
I agree the 326M's look absolutely beautiful, but so does Amber Heard and I wouldn't want to live with her either.
