Stoked to have found this thread!!!

Will likely upgrade my 2017's brakes front and rear because of this thread.

Curious how the OP's header install went and subsequent overall experience?

 

any follow up to this thread? Also how much of a spacer is suggested for the rear?

 

They still work great; I've had to regrease the contact points on the pads once as they were getting noisy at low speeds, but otherwise no complaints in ~15k miles.

The 3mm spacers come with the rear BBK, so no need to purchase it separately.
