I know that 15x7 wheels with 3.5" backspace require some "massaging" (aka
grinding) of the ends of the upper A-arms to fit a TR6 (some folks now use
16x7 wheels, which present none of the problems). Looking at the 15x7s on
my TR6, it looks like if they were 14x7 then the wheel rim would definitely
interfere with the upper A-arm/ball joint.

That's what he SAID, but I suspect (I hope?) that he meant that the wheels
have a 3.5" backspace -- which means that they'd have no offset at all. I
don't know whether 7"-wide wheels will fit on a TR3 without interference,
but wide wheels lead to wide tires, which lead to high cornering forces and
broken axles.
And that's most _definitely_ a poor idea.
