4.6 brakes

[vbx5]

been checking out this forum for a while, excellent tips on not getting ripped by stealer,
now it's time for brakes, i suspect, since i get a steering wheel shimmy with braking. 2002 4.6 67k miles on original pads rotors.
this happened shortly after i mounted winter wheel set up, i didn't use a torque wrench on lug bolts.
i'm concerned about the axix or ebc aftermarket pads that are half the price of stealers pads and much more than 4.4 pads
Anyone with experience with good aftermarket pads for the 4.6?
i plan on using new rotors from the dealer.

thanks
