    What’s the best way to do this? I thought I had it set up perfect last time but coming to a screeching halt, the front brakes locked but the rear did not. This extremely hampered my ability to stop. How do I adequately test without creating flat spots on my tires?

    Just had this problem with a friends car, but it was disk/drum. We had to install a 10lb residual valve to cure the bias.

    Wilwood include some instructions with their valves that should help https://www.wilwood.com/PDF/DataSheets/ds715.pdf (half way down pg2)

    A specialised brake and suspension workshop with brake rollers/Dyno can usually dial them in as well (ideally find someone that does a bit of work on race cars)

    Locking up the brakes is not the fastest way to stop, and you sure don't want the backs locking up first.

    Gravel parking lot won't flat spot them.

    That's an excellent point! It will quickly get you to a baseline to fine tune from without destroying your tires along the way.
