Looks great man. Looks like an ICON kit as the fronts are 2.5's with reservoirs and the rear look to be 2.0 smooth body along with the 2" rear coils as well & tubular UCA's. 285's won't be an issue at all, especially with the TRD Wheels, gonna look killer man.
Just for a heads up, the 4Runner won't sit perfectly level when everything settles as you will have some driver side lean due to the fuel tank and driver weight, as well as the front will start to sag. So adjust the preload on the front coils accordingly. Personally, I adjusted my driver .75" higher on the driver side to even out. IIRC 1 revolution of the shock collar = 1/8" of overall height adjustment.
That spanner wrench will be your buddy in no time.
