front caliper brackets, iX specific?

[rwtags]

anyone know if these are ix specific?
also how much play should the caliper guide pins allow? any is bad? my understanding is they should keep the caliper very stable, no movement is good, 1/8" play good? 1/16" play good? none?

front rotor/Carrier/caliper is the same as RWD vented setups.
I think the rear is also the same, save the rotor.

Not ix specific.

The rear rotor is ix specific. The front is all the same. A little play in the caliper guide pins is ok, 1/8" sounds fine.
