Another brand is Hawk. I believe they make rotors and pads. You
sometimes can find them on Ebay. Hawk street performance is one line
of pads. One thought hyped is that they are low dust. I was curious
if you had retorqued the lug nuts in a cross pattern, then I see you
said 'only when hot'. Good luck and keep us posted in your choice/
results. Does your 4Rnr have a rear proportioning valve? You could
adjust it to have more rear braking. I am happy having done that on
my 2004 Taco.

I believe him (and you), but I have no platform from which I can test what
you guys are telling me, so I can't confirm or deny.

Slots allow the gas to escape, crossdrilling increases the exposed surface
area so that cooling can be distributed more evenly and quicker.

Slots and crossdrilled holes are typically only made on high performance
brake parts, except pads. Low performance brakes don't care, and the pads
may or may not have a slot cut into them, depending on the whim of the
parts-maker. Granted, OEM parts may specify a groove cut into the pad, but
as a practical matter, replacement parts might or might not actually have
the same gorrve, and life isn't going to change if the groove is missing.

It is probably not worth the cost-up to change rotors from a standard rotor
to a slotted and/or crossdrilled rotor if viewed from the perspective of
increased performance. I made the change on my BMW solely for the looks of
the holes and slots, but my driving style does not require holes and slots
and my car does not have holes and slots available from official BMW
sources -- I had to get mine from an aftermarket source.

If anybody has a car that is fitted with standard rotors, making an upgrade
to slotted and crossdrilled rotors is not going to make much difference in
braking performance or reliability.
