in [Toyota]

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.

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. |
