|Your willful ignorance on the subject is impressive.
He asked about the 17Z, we commented on a similar alternative, the 18Z - though I doubt you are all that familiar with either one.
I ran the numbers and it's a very close match to stock in terms of unadjusted brake bias, much closer than a 13" 6 piston front only BBK I can assure you :) Of course it can be further refined with a proportioning valve as previously mentioned, however I'm going to give you the benefit of the doubt and assume you skipped over that part.
But I'm guessing you don't care about the numbers and want some anecdotal evidence about a different platform and brake setup that you don't know anything about but didn't perform as good as OEM.
Have a good evening, I'm done chiming in here.
