claims are only claims.
this thread is really about disc brakes.
with a couple of corollary notes related to the C product.
but there are MANY threads out there on these pie pans...
going back AT LEAST 5 years...
and on less expensive, also "PROVEN" alternatives...
in USAGE i've experienced NO INCREASE in tire life and NO CHANGE in tire temps.
but the wheels have ALSO been balanced correctly at the bead and on the wheel back side...
so MY personal experience with the pie pan/plates is mixed, after nearly 3 YEARS of use.
VERY easy to mount, keeps the wheels a little cleaner...
but NOT much else in the way of MAJOR improvements as advertised.
i do pretend that they reduced the NEED for rebalancing tire/wheels as the tread wears away,
but that may be JUST MY IMAGINATION
(gotta love that song)
also they do NOT fit behind the standard STEEL spare rim supplied by a/s on newer units.
the plates ARE nicely made.
another NICE FEATURE is that SO MANY VENDORS carry them,
AND they can be ordered directly from the maker...
CHOICE (brake options, balancing options, vendors) is a very good thing.
but ALL magic claims should be swallowed in tiny bites and with help nearby in cases of a bad reaction to the magic.
i've read that spam makes a VERY good car wax too...
