Summary: 

I recently put Goodyear VR50 "Gatorback" (205/50VR-15 size) mounted on
Compomotive 3pc 15x6" TH (TurboHub) rims on my 1980 TR7 convertible.  Needless
to say I have noticed a very pronounced performance improvement over my stock
185/70R-13 Goodyears on 13x5.5" steel rims.  Cornering ability is much better:
I can now take corners at speeds which my old tires would begin to break away.
In fact the body lean at these speeds is so pronounced that I reall need anti-
sway bars.  Even more impressive is the great improvement in stopping: stopping
distances are much shorter because the new tires go into lock-up slide at MUCH
higher g's.  These improvements are even more pronounced when I compare
performance in the wet.  The tires do give a somewhat bumpier ride, but the
difference is not very great, just noticable if you are looking for it.  As
for noise, I could not tell any difference, but then convertibles are not
your quietest cars, so maybe the difference is just below the noise threshold
for my car.  Well it's time to relearn the limits of my car, preferably on CA
Highway 1.
